Overview

About Texas

Texas is huge and has many kinds of habitats. Coastal shorebirds and sea turtles share the state with prairie songbirds, pine-forest woodpeckers, and desert reptiles. Eastern forests, central grasslands, subtropical Gulf areas, and western desert mountains are all here. Big migration flyways, large rivers, and a big change in rainfall—from humid coastal plains to dry Trans-Pecos basins—help shape wildlife.

Key places are the Gulf Coast and estuaries (bays, marshes, barrier islands), which are nurseries for fish and places where migratory birds stop. Central prairies and oak savannas support grassland birds and large raptors. The Pineywoods in East Texas hold southeastern forest species. In far West Texas, the Chihuahuan Desert and sky island ranges host desert mammals, bats, and reptiles, with unique mixes on higher slopes.

Wildlife can change quickly across a day's drive, and bird numbers are high along the Central Flyway and Gulf migration corridor.

Physical Features

Geography

Texas spans many biogeographic regions where climate and land create sharp habitat shifts: eastern pine forests and bottomland rivers, central grasslands, and the arid basins, desert scrub, and sky‑island mountains of the Trans‑Pecos. The Gulf Coast has barrier islands, bays, estuaries, and tidal wetlands that draw migratory birds and support fisheries and coastal mammals; rivers and playas provide freshwater stopovers.

Parks & Reserves

Protected Areas

Texas has little public land but includes key protected landscapes and coastal wetlands managed by NPS, USFWS, TPWD, and USFS. Protection centers in the Trans-Pecos (Chihuahuan Desert mountains and river canyons), the Gulf Coast (barrier islands, bays, marshes), and Pineywoods. These areas protect Central Flyway stopovers, sea turtle nesting beaches, sky‑islands, and large riparian and wetland tracts.

Protected Coverage

Approximately ~4-5% of Texas land is under some form of public protected-area management (with stricter biodiversity-focused protection being lower).

  • Invasive feral hogs: rapid expansion statewide has increased predation and habitat damage, affecting ground-nesting birds, reptiles, and wetland systems.
  • Chronic Wasting Disease (CWD) in deer: detected/managed in multiple areas, increasing surveillance and influencing wildlife management practices.
Visit

Wildlife Viewing

Texas has many wildlife habitats: Gulf Coast marshes, barrier islands and estuaries; Hill Country rivers; Panhandle prairies; East Texas pine forests; and Chihuahuan Desert in Trans-Pecos. Visitors can see bird migrations, sea turtle nesting, bats leaving caves, alligators and wetland life, desert night mammals, dolphins and shorebirds. Parks, refuges, state parks and ranches offer many kinds of animals and scenery.

Best Seasons

Spring (Mar-May)

Peak migration and wildflower season: outstanding birding along the Upper Texas Coast and Rio Grande Valley; rookery activity in coastal wetlands; increased activity for reptiles/amphibians after rains; great visibility and comfortable temperatures for Big Bend wildlife drives/hikes. Expect busy weekends at famous birding sites and rapidly changing weather along the coast.

Summer (Jun-Aug)

Coastal life is the headline: sea turtle nesting and hatchling releases on the Gulf; baby sea birds and bustling colonies; excellent dawn/dusk viewing for alligators and wetland mammals. Inland heat is intense-plan early mornings, shaded riparian areas, and higher-elevation spots in the Davis Mountains. Evening bat flights remain a signature Texas experience.

Fall (Sep-Nov)

Second major migration pulse: raptors, shorebirds, and songbirds move through the coast and river corridors; comfortable desert temps return for Big Bend/Trans-Pecos; whooping crane season begins on the central coast (late fall). Fall fronts can produce "fallout" birding days along the coast when migrants drop in by the thousands.

Winter (Dec-Feb)

Prime season for coastal and South Texas specialties: wintering waterfowl and shorebirds on the coast; reliable whooping crane viewing from Rockport/Aransas area; Rio Grande Valley birding at its easiest (mild temps) with tropical specialties. Desert nights are cold but clear-great for dawn wildlife drives and tracking in Big Bend.

Top Wildlife Experiences

  • Watch a massive bat emergence at dusk at Congress Avenue Bridge (Austin) or Bracken Cave Preserve (near San Antonio; seasonal guided access) for one of North America's most iconic wildlife spectacles.
  • Take a whooping crane boat tour from Rockport/Fulton to view endangered whooping cranes wintering around Aransas National Wildlife Refuge (best Nov-Mar).
  • Bird the 'Great Texas Coastal Birding Trail' hotspots-especially High Island/Sabine Woods, Bolivar Flats, and Anahuac National Wildlife Refuge-during spring or fall migration for warblers, shorebirds, and occasional rarities.
  • Paddle or walk the boardwalks at Caddo Lake (near Karnack) for cypress swamp wildlife: barred owls, prothonotary warblers (spring/summer), river otters, and alligators (warmer months).
  • Visit Santa Ana National Wildlife Refuge and nearby World Birding Center sites (McAllen-Mission-Weslaco area) to look for green jays, plain chachalacas, great kiskadees, and butterflies-especially rewarding in winter and spring.
  • Plan a Big Bend National Park wildlife loop: dawn at Rio Grande Village and the river for javelina and birds, desert drives for roadrunners and raptors, and night drives for owls and nocturnal mammals (best Oct-Apr).
  • Go coastal for sea turtle nesting and hatchling events on South Padre Island (Sea Turtle, Inc.) or Padre Island National Seashore (Kemp's ridley nesting season typically spring-summer; programs vary by year).
  • Explore the Davis Mountains / Fort Davis area for high-elevation birding (e.g., Montezuma quail chances with effort, hummingbirds seasonally) and combine with a guided nighttime search for desert-adapted mammals in the Trans-Pecos (best spring/fall).

Habitats

Ecosystems

Texas spans the humid Gulf Coast to the dry interior Southwest, causing sharp east–west shifts in rain, plants, water. Habitats: pine forests east; tallgrass and oak savannas center; thornscrub and subtropical coastal plains south; deserts, canyons, sky‑islands in Trans‑Pecos. Rivers such as Rio Grande, Colorado, Brazos link uplands to Gulf estuaries and barrier islands, supporting many species and migratory birds.

Biomes

Temperate Forest

Humid forests dominate the Pineywoods and extend into river bottoms and upland oak-hickory systems; includes pine-hardwood mosaics and bottomland hardwood floodplains.

Highest in East Texas; patchy westward along river corridors and higher-rainfall uplands.

Temperate Grassland

Prairies and open grasslands (tallgrass to mixed/shortgrass) occur from the Gulf Prairie and central prairies into the Panhandle; often intergrades with oak savanna and shrubland.

Large belt across central and northern Texas; extensive in the Panhandle/High Plains and historically widespread in coastal prairies.

Savanna

Oak savannas and parklands where trees (often post oak, live oak, mesquite) are scattered over grass understories; common in transition zones between forest and prairie and in parts of South Texas brush country.

Broad transitional swaths in Central Texas and parts of North and South Texas.

Hot Desert

Chihuahuan Desert landscapes in the Trans-Pecos: creosote bush flats, desert grasslands, lechuguilla/agave slopes, and canyon systems; includes arid basin-and-range valleys and foothills.

Far West Texas (Trans-Pecos); dominant biome there.

Freshwater

Major river networks, reservoirs, springs, and aquifers (e.g., Edwards Aquifer, springs of the Hill Country) support riparian forests, spring runs, and diverse fish and amphibian communities.

Statewide, concentrated along major basins and spring regions; reservoir-dense in many central/east watersheds.

Marine

Gulf of Mexico coastal waters and nearshore shelf support seagrass beds, oyster reefs, fisheries, and coastal pelagic systems; strong influence from large estuaries and barrier-island dynamics.

Along the entire Texas coastline and adjacent Gulf waters.

Wetland

Coastal marshes, estuarine wetlands, bottomland swamps, playa wetlands, and riparian floodplain wetlands; critical for migratory waterfowl and shorebirds.

Most extensive on the upper/mid coast and in major river floodplains; localized in Panhandle playas and interior lowlands.

Habitats

Forest

Pine-hardwood and mixed forests of the Pineywoods; includes extensive managed timberlands and protected remnants.

Deciduous Forest

Oak-hickory woodlands/forests and bottomland hardwoods along rivers (e.g., Trinity, Brazos, Sabine, Neches).

Coniferous Forest

Loblolly/shortleaf pine systems in East Texas; longleaf pine restoration occurs in limited areas near the coastal plain.

Woodland

Juniper-oak woodlands in the Edwards Plateau/Hill Country and post oak woodlands in the Cross Timbers.

Grassland

Mixed- and shortgrass communities in the Panhandle/High Plains; grazing-adapted systems with prairie birds and grassland mammals.

Prairie

Gulf Coast tallgrass prairie remnants and Blackland Prairie; highly converted to agriculture/urban uses but ecologically significant.

Savanna

Oak savanna and mesquite savanna mosaics, especially in transition zones between prairie and woodland/forest.

Steppe

Semi-arid grass-shrub transitions on the High Plains and western edges of the Rolling Plains, grading toward desert grasslands.

Shrubland

South Texas thornscrub and brush country (mesquite, acacia, prickly pear), important for subtropical bird assemblages.

Desert

Chihuahuan Desert basins, bajadas, and arroyos in the Trans-Pecos, with creosote, yucca, agave, and desert grasslands.

Mountain

Sky-island mountain ranges in far West Texas (e.g., Davis, Guadalupe, Chisos) creating cooler, wetter refugia and elevational zonation.

Cave

Karst caves and sink systems of Central Texas (Edwards Plateau), including bat roosts and endemic cave invertebrates.

Cliff/Rocky Outcrop

Limestone escarpments and canyon walls (e.g., Caprock Escarpment, Hill Country canyons, Big Bend region) supporting cliff-nesting birds and specialized plants.

Lake

Natural lakes are limited, but large reservoirs are widespread (e.g., Sam Rayburn, Livingston, Texoma) supporting fisheries and waterbirds.

River/Stream

Large river systems (Rio Grande, Pecos, Colorado, Brazos, Trinity, Sabine, Nueces) with riparian corridors and floodplain habitats.

Pond

Stock ponds and small impoundments are common statewide; important for amphibians and localized wetland functions.

Open Ocean

Gulf pelagic waters off the Texas coast supporting migratory fishes, seabirds, and marine mammals.

Deep Sea

Beyond the continental shelf in the Gulf (far offshore of Texas) with deep benthic communities and canyon/seeps in broader Gulf regions.

Seabed/Benthic

Nearshore and shelf seafloor habitats (sand/mud, oyster reef structures, seagrass-associated sediments) supporting benthic invertebrates and demersal fish.

Urban

Large metro regions (Houston, DFW, San Antonio, Austin, El Paso) create urban habitat mosaics and intensify coastal and riparian pressures.

Suburban

Rapidly expanding suburban matrices, especially along the I-35 corridor and around major metros, fragmenting prairies/woodlands.

Agricultural/Farmland

Row crops, rangeland, and pasture dominate many plains and prairie regions; major driver of habitat conversion, especially in Blackland and coastal prairies.

Plantation

Managed timber plantations in East Texas (pine silviculture) function as plantation-like production forests with varying understory and wildlife value.

Protection

Conservation

Primary Threats

  • Conversion and fragmentation of native prairies and grasslands (among the most reduced ecosystems in Texas), coastal marshes, and riparian corridors due to development, reservoir construction, brush encroachment, and land-use change. Critical pinch points include remaining coastal wetlands/rookeries, Hill Country stream and spring habitats, and intact Trans-Pecos desert grasslands.
  • Rapid growth in metros such as Houston, Dallas-Fort Worth, Austin-San Antonio, and the Rio Grande Valley drives subdivision of rangelands and forests, increases road density and light/noise, and intensifies water demand that reduces river flows needed by bays/estuaries and spring systems.
  • Row-crop and intensive agriculture (including irrigation) can reduce native cover, increase runoff, and simplify landscapes in the Panhandle, Gulf Coast Prairie, and parts of South Texas-pressuring grassland birds, pollinators, and riparian species while elevating water withdrawals from rivers and aquifers.
  • Highway expansion, border infrastructure in South Texas, transmission lines, and extensive oil/gas and renewable-energy buildout create barriers, collision risk (birds/bats), and habitat fragmentation. Along the Gulf Coast, dredging and ship-channel maintenance alter shorelines and estuarine habitat.
  • Over-allocation and groundwater pumping (notably Edwards Aquifer and other regional aquifers) reduce spring discharge and baseflows, stressing spring- and river-dependent species and lowering freshwater inflows that sustain productivity in bays like Galveston, Matagorda, and Laguna Madre.
  • Hotter temperatures and more severe drought amplify wildfire and heat stress, shrink wetlands and playa lakes used by migratory birds, and reduce river/spring flows. Sea-level rise and stronger storm impacts increase coastal erosion and inundation of marshes and barrier islands, affecting shorebirds and sea turtle nesting habitat.
  • Nutrient and sediment runoff from urban and agricultural areas contributes to water-quality degradation in rivers and estuaries; industrial and petrochemical corridors (especially near Houston/Gulf Coast) increase risk of spills and chronic contamination. Plastic and marine debris affect coastal wildlife, including sea turtles.
  • Aquatic invasives (e.g., zebra mussels in some reservoirs) alter food webs and infrastructure; invasive plants (e.g., saltcedar in riparian areas, invasive grasses) change fire regimes and displace native vegetation. Feral hogs degrade wetlands and riparian zones statewide, increasing erosion and impacting ground-nesting birds and herpetofauna.
  • Chronic wasting disease in some deer populations prompts intensive management; amphibian diseases and fish pathogens can compound stress where water temperatures rise and habitats shrink. Dense wildlife concentrations around limited water during drought can elevate disease transmission risk.
  • While regulated hunting is a major funding source for conservation, localized overharvest risk can occur for certain game or sensitive populations when combined with drought, habitat loss, or poor enforcement; additional pressure can occur on unregulated take of some nongame species.
  • Illegal collection and trade of native reptiles (e.g., some tortoises and snakes) and birds can affect local populations, particularly in accessible habitats in West and South Texas, though impacts vary by species and enforcement intensity.
  • Fishing pressure in the Gulf and coastal bays can affect forage bases and predator dynamics; management of key sportfish (e.g., red drum, spotted seatrout) and bycatch reduction remains important, alongside habitat protection for seagrass and oyster reefs.
  • High recreational use of beaches, dunes, and coastal flats can disturb nesting shorebirds and sea turtles; off-road vehicles and increasing coastal tourism can degrade dune systems and nesting areas, especially on barrier islands.
  • Conflicts include depredation concerns (coyotes, bobcats), expanding interactions with black bears in parts of West Texas, and crop/lawn damage by deer and feral hogs. Predator control practices can have non-target impacts on sensitive carnivores and scavengers.
  • River regulation (dams, channelization), altered flooding regimes, and water diversions change sediment delivery and freshwater inflows to estuaries; coastal engineering and shoreline armoring reduce natural marsh migration and alter barrier island dynamics.
  • Extraction activities (notably oil/gas; localized aggregates and other mining) can fragment habitats, increase road networks, elevate spill risk, and degrade water quality-particularly impactful in sensitive areas like desert springs, playas, and coastal watersheds.
  • Commercial forestry in East Texas can reduce mature/old forest structure if not managed for biodiversity; fragmentation and short rotation cycles can affect forest interior species. However, certification and wildlife-friendly forestry practices can mitigate impacts where adopted.
  • Small, isolated populations of rare spring/river endemics (e.g., Edwards Plateau aquifer-associated species) face genetic risks from restricted ranges and fragmented habitats; coastal nesting populations can also be vulnerable when key nesting sites are limited.
Fun Facts

Did You Know?

The 'bat clouds' over central Texas are Mexican free-tailed bats, major insect eaters: one bat can eat a part of its body weight in insects nightly, and a colony the size of Bracken Cave can remove tons in peak season.

Texas horned lizards have one of the strangest defenses in North America: they can squirt blood from the corners of their eyes to deter predators (especially canids).

Texas's most abundant large mammal in many places isn't native: feral hogs descend from domestic pigs and Eurasian wild boar introduced by people, and they now cause extensive damage to habitats, crops, and ground-nesting wildlife.

The "wild cat" most Texans don't realize still survives in the U.S. is the ocelot: the only remaining breeding populations in the United States are in deep South Texas (notably in and around Laguna Atascosa National Wildlife Refuge).

Alligator gar-native to Texas rivers and bayous-are among North America's largest freshwater fishes, capable of reaching well over 6 feet long; despite their fearsome look, they're ancient, air-breathing-adapted predators that often surface to gulp air.

Bracken Cave Preserve (near San Antonio) hosts the world's largest known bat colony: Mexican free-tailed bats often number in the tens of millions, creating one of the planet's biggest nightly mammal emergences.

Texas is among the most bird-diverse U.S. states-more than 640 bird species have been documented-because it sits where Eastern, Western, tropical, desert, and coastal flyways/habitats overlap.

Aransas National Wildlife Refuge on the Texas Gulf Coast is the wintering grounds for the only remaining natural, self-sustaining wild migratory population of whooping cranes (they breed in Canada and migrate to Texas each year).

Padre Island National Seashore protects the longest stretch of undeveloped barrier island in the United States and is also the most important nesting area in the U.S. for the critically endangered Kemp's ridley sea turtle.

The Laguna Madre (Texas) is the largest hypersaline lagoon system in the United States; its extensive seagrass beds support exceptionally large concentrations of wintering waterfowl, including redheads and other diving ducks.

Home to over 31 million people, Texas is one of the largest states in the country by both population and land mass. The colloquialism that “everything is bigger in Texas” is fitting, as it encompasses 268,597 square miles of terrain that varies from mountain forests to extensive coastline.

Texas has more than 800 different habitat types. This greatly diverse terrain gives rise to a tremendous variety of native and endemic wildlife. The list of Texas’s native and introduced animals includes 540 species of birds and 142 species of mammals, amphibians, and other animals.

Texas is proud to call itself “the battiest state in the nation.” It is home to 32 of the 47 species of bats native to the U.S.

Texas’ biggest predators, in terms of size, include cougars (mountain lions), and ocelots. However, the ocelot population is down to about 35 or fewer members living on the Mexican border, so they aren’t much of a threat. Black bears also exist in Texas in Big Bend country, particularly the national park, but they are also rare because there are only 30-40 bears left.

The alligator is a different story. Found in the coastal and bayou areas, it is one the largest animals in Texas. The state’s Parks and Wildlife Department says there are 400,000-500,000 alligators! Another big population of a large animal in Texas is that of the wild hog. There are 3 million of them spread across nearly every county, and they are a dangerous nuisance.

Some people worry about the 3,000-5,000 tigers in Texas, which is the most outside their native habitats. However, these tigers are all in zoos or sanctuaries or are privately owned as pets. In Texas, it is legal to have a pet tiger, but there is no database to keep track of them. Occasionally, one will escape, and that is a security problem. It’s the same story for pythons.

Camels were introduced to west Texas by the army in the late 1800s, but the experiment didn’t work, so the camels were sold. A few remained in the wild, but the last sighting was in 1941.

The next size of animals in Texas are common forest mammals like bobcats and badgers. Its larger rodents include pocket gophers, tree squirrels, porcupines, beavers, and nutria.

The state’s birds include doves, kestrels, finches, owls, and bald eagles. In the mountain areas, you’ll find river otters, flying squirrels, and hawks. The arid desert stretches are home to many of the world’s rarest amphibians and reptiles. The nine-banded armadillo, Texas rat snake, and short-lined skink lizard are some of the weird critters you will find there.

Texas is also home to some animals with odd names like the Northern black-bellied whistling duck, the Gulf stone crab and the Texas blind salamander.

Texas has over 350 miles of coastline. This includes South Padre Island, which is the world’s largest barrier island. The shoreline is home to many marine animals, including fiddler crabs, roseate spoonbills, alligators, sharks, and sea turtles.

The Official Animals of Texas

Texas has eight official state animals:

  • The State small mammal is the Nine-banded armadillo: This strange, nocturnal animal (Dasypus novemcinctus) inhabits forests, grasslands and dry scrub deserts. It is the most widespread of the armadillo species and is listed as “least concern” for conservation status.
  • The State large mammal is the Texas longhorn: This breed of cattle is famous for its long horns extending more than 10 feet across. Once a popular breed in Texas, longhorns fell out of popularity in the early 1900s. They were saved from extinction when biologists from the U.S. Forest Service established longhorn sanctuaries in Texas. Today, you can see them at various nature preserves throughout the state.
  • The State flying mammal is the Mexican free-tailed bat: Sometimes called the Brazilian free-tailed bat, this medium-sized bat (Tadarida brasiliensis) is native to the Americas. Mexican free-tailed bats are abundant in North America, Central America, and parts of South America.
  • The State bird is the Northern Mockingbird: Texas decided in 1927 that it would cement a special bond between the state and a beautiful feathered creature. The northern mockingbird (Mimus polyglottos) was officially declared the state bird. With its melodious songs, long tail, and legs, this medium-sized bird immediately captured the hearts of all Texans.
  • The State fish is the Guadalupe Bass: One of the smaller black bass species, it has adapted to live in small streams in Central Texas. This fish typically reaches around 12 inches long, is relatively easy to catch, and is popular among sports fishermen.
  • The State reptile is the Texas horned lizard: This reptile is known as the “horny toad.” It is flat-bodied with numerous prominent horns on its head. Brownish with two rows of fringed scales along each side of the body, it is the only species of horned lizard to have dark brown stripes that radiate downward from the eyes and across the top of the head.
  • The State insect is the Monarch Butterfly: Known for their very distinct orange, black, and white coloring, this butterfly goes through four stages in its life cycle: egg, larvae, pupa, and adult. When they migrate in the fall, a Monarch Butterfly will travel thousands of miles. Eggs are laid on a food source, usually milkweeds, but that source is decreasing because of herbicides.
  • The State dog is the Blue Lacy: These are athletic, energetic working animals, but also family-friendly. They are intelligent, easy to train, and have managed farm/ranch livestock since they were introduce in the mid-1800s by . Their sleek, clean coats are a blue-gray.

Where To Find The Top Wild Animals in Texas

Texas has many activities devoted to birding and wildlife watching.

Bird City Texas is a statewide program that encourages birders of all levels and in all parts of the state to create bird sanctuaries and feeding spaces. Wildlife and birding tours frequently take visitors to places where they can see egrets, tanagers, whooping cranes, kingfishers, green parakeets, chachalacas, elf owls, and many of the country’s rarest birds.

With more than 20 million roosting Mexican free-tailed bats, Bracken Cave Preserve, near San Antonio, is the largest bat colony in the world. Congress Avenue Bridge in Austin is the country’s largest urban bat colony. There are many official bat-watching sites in the state. There are many other places to see bats in Texas, including Clarity Tunnel in Caprock Canyons State Park and the Ecker James River Bat Cave Preserve.

Some of Texas’s bats include the Mexican long-nosed bat (Leptonycteris nivalis), big brown bat (Eptesicus fuscus), Western mastiff bat (Eumops perotis), and Southern yellow bat (Lasiurus ega).

Sea Turtle, Inc., is a sea turtle rescue in South Padre Island that was originally formed to preserve the Kemp’s Ridley sea turtle. The sanctuary now has a hatchling release program that is open to the public.

Prairie Dog Town is a sanctuary for black-tailed prairie dogs (Cynomys ludovicianus) that was established in 1936 by a Lubbock, Texas, man who was worried that nearby atomic poisoning would kill the rodents. The city has maintained the sanctuary ever since. Prairie dogs are considered a keystone species, meaning that many members of the same ecosystem depend on them for the proper ecological balance.

Tiger Creek Animal Sanctuary in Tyler, Texas, is a sanctuary for exotic big cats that were bought as pets and then abandoned, abused or neglected.

Laguna Atascosa National Wildlife Refuge is an ideal place to see birds and wildlife while hiking, swimming and biking.

What Wild Animals Can You Find in Texas?

You can find almost any type of animal you’re looking for. The list includes animals that are hard to see in other states, including alligators, sea turtles, and dolphins. It has some weird animals like the ghost-faced bat and the Texas horned lizard.

Texas is known for its big ranches. In fact, it has more cattle than any other state.

One of the rarest animals in Texas is the ringtail. Ringtails are about the size of a cat and have long, raccoon-like tails. These nocturnal animals are excellent at catching mice, and they were called “miner’s cats” because many miners adopted them as pets. The ringtails helped clear the mines of rats, and the miners kept the ringtails safe. Today, it is illegal to keep a wild ringtail as a pet.

Rarest Animals in Texas

  • A melanistic (black hair) mule deer fawn with a bit of white fur, described by Texas Parks and Wildlife as “a one-in-a-million anomaly” was seen in March of 2020 in the Trans-Pecos region of West Texas. A mule deer is normally brown and white. Finding this black-haired mule deer is like finding an albino among other species.
  • Otherwise, the rarest animals in Texas include, of course, all the endangered species. Besides those listed by A-Z Animals, earth.org has a list of seven of the most endanged animals in Texas that includes: the Ocelot, Kemp’s Ridley Sea Turtle, Golden-cheeked Warbler, Whooping Crane, Texas Horned Lizard, Texas Kangaroo Rat, and Black Bears.

Largest Animals in Texas

  • Largest fish: The alligator gar is the largest fish in the Texas river system and the largest member of the gar family. This giant fish reaches up to six feet in length and can weigh over 300 pounds, although it’s surprisingly passive and sluggish, given its frightening appearance. This torpedo-shaped fish is native to many rivers and lakes in the southern United States. It’s a living fossil with a swim bladder lung that helps supplement its gills and allows it to breathe air, which is why the alligator gar can be found in waters that would kill other fish through suffocation.
  • Largest snake: The prize for the largest snake in Texas goes to the Texas indigo snake for its impressive length. Common in south Texas and northern Mexico, the farmers and ranchers love them because this nonvenomous colubrid eats venomous snakes like the rattlesnake. It even seems to be immune to rattlesnake venom. Its genus name, Drymarchon, means “Lord of the Forest,” and the name fits because the Texas indigo snake can measure over eight feet long. These snakes appear in many Youtube videos in a death match with rattlers, often winning the fight, even after several bites from the rattler.
  • Largest bird: The American white pelican boasts a wingspan that reaches 9 feet, and the bird weights up to 30 pounds, thus making it the largest bird in Texas. Its bright white plumage and black flight feathers are visible from a distance. Pelicans live in or near marshes, lakes, and rivers. They primarily eat fish they catch using their pouches to skim the water’s surface, but they will also eat crayfish and salamanders. They leave the water only for migration. They spend winters in Texas, then migrate north again to breeding grounds in the western United States and Canada.
  • Largest mammal: The Texas longhorn is the largest mammal and the largest animal of any kind in Texas. It also happens to be the state mammal. This bovine behemoth weighs up to 1,500 pounds and stands five feet tall at the shoulder. The horns are massive and can measure up to 11 feet from tip to tip. Descendents of cattle brought by Spanish Explorers in the late 1400’s, the Longhorn became feral, but later mixed with other Spanish and Mexican breeds. Over the centuries, the cattle became outrageously tough, weathering freezing as well as blazing hot temperatures. Longhorns can survive weather conditions that other breeds can’t. They’re also extremely protective of their herd, standing their ground when any member is threatened.
  • Largest flying insect: The giant green darner wins for largest flying insect in Texas, and that’s in a state with over 30,000 insect and arachnid species. This flying insect is not only pretty, but also it eats mosquitoes and other pesky bugs. The giant green darner is a blue-green iridescent beauty that ranges from Texas to California and north to Nevada and Utah. According to BugGuide.net, it’s a huge dragonfly that can reach up to five inches long, from its eyes to the end of its abdomen. It inhabits areas around ponds, marshes, and lakes.

  • Sharks: Texas has the longest barrier island in the world, and sharks are present in its waters. Great water sharks have recently been recorded outside Texas’ shores and bull sharks are also present.
  • Feral hogs: Feral hogs have caused very few fatalities, but they are sizeable animals, so there can be mauling. Since they are carriers of diseases that can be passed on to humans such as tuberculosis, hepatitis E and influenza A, any wound could lead to serious consequences.
