Appearance

Primary Colors
Secondary Colors
Skin Type Tliltocatl albopilosus has a hard exoskeleton densely covered in setae (including defensive urticating hairs typical of New World theraphosids). Setae are velvety to bristly and very curled.
Distinctive Features
  • Dense, curly/bristly golden-brown setae over legs, carapace, and abdomen-signature 'curlyhair' look.
  • New World defensive urticating hairs on the abdomen; primary defense is brushing/kicking hairs rather than severe venom effects (medically significant envenomation is uncommon; irritation from hairs is typically the main concern).
  • Terrestrial, ground-dwelling build with a sturdy carapace and thick legs; frequently associated with burrow use or opportunistic sheltering under objects in captivity/habitat.
  • Color tone can shift after molts: freshly molted individuals often appear darker and more contrasty before hairs dull to a warmer brown/golden sheen.
  • Tliltocatl albopilosus (Curlyhair tarantula) is mostly calm; it usually runs away or kicks hairs instead of biting. It lives on the ground and uses burrows in Central America, especially Nicaragua and Costa Rica.

Sexual Dimorphism

Curlyhair tarantula: males and females look different. Adult males are slimmer, have longer legs and mating organs. Females are heavier and live much longer. In captivity females often live about 10–20+ years; males about 3–7 years after becoming adults; numbers from captive records.

♂
  • More slender abdomen and overall lighter, leggier appearance at maturity (proportionally longer legs).
  • Adult males develop tibial apophyses ('mating hooks') on the first pair of legs and emboli on the pedipalps (palpal bulbs) for sperm transfer.
  • Typically shorter post-maturity lifespan; may roam more when mature (in captivity often more restless/wandering).
♀
  • More robust, heavier-bodied build with a rounder abdomen; generally larger overall mass even when leg span overlaps with males.
  • Lack tibial apophyses and palpal bulbs; pedipalps remain leg-like.
  • Typically longer-lived; often more sedentary and strongly shelter/burrow-oriented once established.

Did You Know?

Scientific name: Tliltocatl albopilosus (formerly widely listed as Brachypelma albopilosum in the hobby and older literature).

Adult size is typically ~12-15 cm leg span; body length commonly ~5-7 cm.

Females are long-lived: commonly ~12-20+ years in captivity; males typically ~3-6 years (shorter adult lifespan after maturation is normal for male theraphosids).

Like other New World tarantulas, it can defend itself by kicking urticating hairs from the abdomen-an effective deterrent that can cause itching and eye/airway irritation.

Despite the "hairy" look, the curliness is from dense, bristly setae; the species epithet albopilosus means "white-haired."

It's primarily a sit-and-wait ambush predator, relying on vibration sensing more than eyesight.

The genus Tliltocatl includes several terrestrial, burrowing tarantulas-sharing urticating hairs and a generally ground-adapted build, but differing widely in coloration and habitat preferences.

Unique Adaptations

  • Urticating setae (New World defense): specialized abdominal hairs that can be kicked off toward threats; urticating hair types were formalized in theraphosids by Cooke, Roth & Miller (1972), and Tliltocatl/Brachypelma-type terrestrials are known for effective hair defenses.
  • Vibration-first sensory ecology: sensitive slit sensilla and leg setae detect substrate vibrations-key for hunting and threat detection in low-light conditions.
  • Burrow microclimate control: using silk and soil architecture to stabilize humidity and temperature (important for successful molting).
  • Powerful, short-range locomotion and strike: robust legs and hydraulic limb extension enable sudden, high-speed prey capture.
  • Cryptic coloration + textured setae: earth-toned body and bristly coat help break up outline against leaf litter/soil in terrestrial habitats.

Interesting Behaviors

  • Burrow-and-shelter living: juveniles and adults typically use a hide or excavate/modify a burrow, often lining it with silk and using it as a humidity-stable retreat.
  • Nocturnal/crepuscular activity: most surface activity (foraging, webbing at the entrance) is concentrated after dusk.
  • Sit-and-wait hunting: remains motionless near a burrow entrance, then strikes rapidly when prey vibrations are detected.
  • Defensive displays: may raise the front legs and expose fangs; more commonly relies on flicking urticating hairs rather than biting.
  • Silk use on the ground: lays down silk "mats" and trip-lines that help detect prey and provide traction.
  • Molting behavior: will fast and become reclusive before ecdysis; often spins a molting mat and flips onto its back to shed the exoskeleton.
  • Male wandering after maturity: mature males typically become more roam-prone as they search for females, reflecting the reproductive strategy of many theraphosids.

Cultural Significance

In Central America tarantulas can cause fear or respect. Tliltocatl albopilosus is important in the global pet trade as a beginner-friendly New World terrestrial (ground-dwelling) tarantula. Hairy tarantulas are also linked to weaving, patience, and stories.

Myths & Legends

Mesoamerican weaving symbolism: across parts of Mesoamerica, spiders are widely associated with weaving and craft-an idea that resonates with tarantulas' silk use (even though they don't make aerial webs like orb-weavers).

In Maya culture, weaving is sacred and linked to powerful people; spiders often stand for thread-making and patient skill in local stories and art designs.

Anansi (West African/Afro-Caribbean folklore): Anansi the spider is the quintessential trickster-clever, persistent, and story-bearing; while not a tarantula, this famous spider figure often colors modern "spider meanings" worldwide, including for large tarantulas kept as pets.

Arachne (Greek tradition): the mortal weaver Arachne is transformed into a spider, a lasting legend linking spiders to mastery, pride, and the origins of spinning/weaving-commonly referenced whenever notable spiders (including tarantulas) are discussed.

Spider Grandmother (Hopi and other Indigenous North American traditions): a benevolent spider figure associated with creation, protection, and teaching; although geographically distant from this species, it's among the most influential "spider-as-helper" narratives in the Americas.

Tliltocatl albopilosus is a solitary tarantula. Males roam and may mate with many females; females can store sperm. Mating is brief via sperm webs and pedipalps. Females live much longer, guard one egg sac with hundreds, no care after young leave.

Behavior & Ecology

Social No established collective noun (typically solitary) Group: 1
Activity Nocturnal, Crepuscular
Diet Carnivore Primarily insects (for example crickets, grasshoppers, and other similar prey); may also take small vertebrates opportunistically.

Temperament

Generally docile/low-reactivity relative to many other large theraphosids in captivity; commonly chooses retreat over escalation when disturbed (noting strong individual variation).
Curlyhair tarantula (Tliltocatl albopilosus) has typical New World defenses: threat pose, retreat into its burrow or hide, and use of urticating hairs (setae) to deter predators.
Biting is usually a last-resort defense; risk is context-dependent (handling, restraint, or forced contact).

Communication

No airborne vocalizations documented; communication is primarily non-vocal As for spiders generally; Foelix, 2011
Chemical communication via pheromones/chemical cues deposited on silk draglines and within the retreat; males track female cues to locate mates Foelix, 2011
Substrate-borne vibratory signaling during courtship Male 'drumming'/tapping transmitted through ground/silk) and close-range tactile signaling between legs/pedipalps (Foelix, 2011
Silk use as an information medium Retreat/dragline silk conveying occupancy and reproductive status cues), consistent with spider silk's multi-function signaling role (Foelix, 2011
Defensive signaling using urticating hairs Rapid abdominal flicking to release barbed setae) and visual display (threat posture); urticating hairs in theraphosids characterized in Cooke, Roth & Miller (1972

Ecological Role

Ground-dwelling generalist mesopredator that helps regulate populations of nocturnal terrestrial arthropods; also acts as prey for vertebrate predators and contributes to soil turnover through burrowing.

Top-down control of insect and other arthropod populations in leaf-litter and ground-layer communities Energy transfer from invertebrate biomass to higher trophic levels (as prey for birds, reptiles, mammals, and parasitoids) Soil aeration/bioturbation via burrow excavation and maintenance Nutrient cycling by concentrating prey remains (carcasses/exuviae) around retreats

Human Interaction

Domestication Status

Wild

Tliltocatl albopilosus (Curlyhair Tarantula) is a wild New World (Central American) land theraphosid not domesticated but widely kept via long-established captive breeding. It is common in the pet trade, education, and research; some illegal wild collecting occurs. In captivity it is calm, 12–15 cm legspan, females live ~10–15+ years, males ~4–6.

Danger Level

Low
  • Urticating hairs: defensive hair-flicking can cause skin irritation/itching and, if airborne hairs contact eyes/airways, can cause significant conjunctival/respiratory irritation (risk increases during rehousing/cleaning).
  • Bite: generally uncommon in this docile New World species; venom effects in humans are typically localized pain/swelling, but severity varies by individual and allergy is possible.
  • Secondary infection risk from any puncture wound if mishandled and not cleaned.

As a Pet

One of the furriest tarantulas in the world.

Curly hair tarantulas do have long wooly hair but it is certainly not curly like a goldendoodle. However they do have some of the longest hairs of all the tarantula species. There are around 1,000 different species of these large full-bodied spiders. Curly hair tarantulas are from Central America including Honduras, Nicaragua and Costa Rica. Recently the species has been split into two distinct breeds with Honduran curly hairs in one and Nicaraguan/Costa Rican in the other. They can get to be 3-4 inches long with a leg span of 5-6 inches.

Amazing Curly Hair Tarantula Facts

  • They bodies and legs are covered in golden-brown bristles or hairs.
  • Curly hair tarantulas can get to be 4-5 inches long.
  • They molt their exoskeleton to make room for their growing bodies.
  • The females can live more than 20 years.
  • They can be kept as a pet and are easy to raise.

Curly Hair Tarantula Scientific Name

The scientific name of the Curly hair tarantula is Tliltocatl albopilosus. They were previously known as Brachypelma albopilosum but are now two breeds. Tliltocatl albopilosus refers to the Nicaraguan curly hairs and Brachypelma albopilosum refers to the Honduran curly hairs.

Curly Hair Tarantula Appearance

Curly hair tarantulas

Curly hair tarantulas can be kept as a pet and are easy to raise.

There are three different colorations of the Curly hair tarantula. Their bodies are all about the same color, dark gray, but the hair colors vary. One type has mostly grayish hairs with a few pinkish hairs interspersed. Another has mostly pink hairs and a third has a bright copper color. Quick note that they don’t actually have “hair” with the bristles actually being called setae, however for the familiarity of their look we will refer to it as hair.

When they reach adulthood they get to be around 3 inches long, the same length as a credit card, with a leg span of 4-5 inches. The females are a little more stout than the males. They have eight segmented legs along with two pedipalps at the front of their body that look like an extra set of arms. They are used for grabbing and holding prey and the males use them in mating.

Curly Hair Tarantula Behavior

Curly hair tarantulas are burrowing animals that can live in a variety of habitats. They are found in both dense jungles and dry deserts. They spend most of their time buried deep in their burrows only coming out at night to hunt for food. Curly hair tarantulas are solitary animals with only one tarantula living in each hole. The entrance to the burrow is covered with a web to protect it.

At night Curly hairs come out to hunt for their prey. They use their size to overpower smaller animals like crickets, roaches, and grasshoppers. They grab their prey, bite with their fangs, inject it with venom and then ball it up with their webs. Using digestive juices they liquefy their victim before sucking their insides up for dinner. They can actually go for months without eating.

If a tarantula is threatened they can flick the urticating hairs off their back causing an irritation to the predator. They may also rear up on their back legs and wave their front legs, making a hissing noise to intimidate the predator.

Curly hair tarantulas are docile and have an easy going temperament. They rarely bite which is another reason they make good pets. They can be a little too low key as pets at times having periods where they move little to none, making them less exciting to watch.

Curly Hair Tarantula Habitat

Curly hair tarantulas live in tropical grasslands, preferring the warm climates that South America provides. They have populations in Honduras, Nicaragua and Costa Rica. Some can be found in the cleared areas of rain forests finding shelter at the base of tall Acacia or Mahogany trees.

Curly hairs are burrowing tarantulas and will live in a burrow in the ground that they either dig or remodel from a previous animal. During the day they spend their time deep in their burrows resting. They are nocturnal and come out at night to hunt and find food. They can create different tunnels at different levels in their burrows to help adjust to the current climate.

As solitary animals you will find one tarantula per burrow with the burrows spaced a good distance apart. The only time they interact with others of their species is during the mating season when the males leave their burrow in search of a mate.

Curly Hair Tarantula Predators and Threats

The main predators of Curly hair tarantulas is the tarantula hawk. It is not a hawk at all but a wasp that uses tarantulas as food for their young. They swoop down and sting an unsuspecting tarantula then haul it off to a burrow where they bury it alive. But before burying it they lay one egg on its paralyzed abdomen. That egg will hatch releasing a larvae that feeds on the still alive tarantula. Sounds brutal but this circle of life keeps tarantulas in check and tarantula hawks thriving.

Other predators include snakes, lizards, birds, and occasionally fox and coyote. Curly hair tarantulas spend most of their day hidden in their burrow resting which helps them avoid predators in broad daylight. At night they do not venture far from their burrow preferring to lurk at the entrance waiting for prey to wander by.  

One tactic Curly hair tarantulas use to avoid predators is to stay hidden in their burrows during daylight hours. During the night their setae (or bristles) work like sensory structures to alert them to movement. If they are threatened by a predator they are more likely to flee than fight.

 What Eats Curly Hair Tarantulas?

The main animals that eat curly hair tarantulas are tarantula hawks, snakes, lizards and birds. Animals that are nocturnal are the most likely to encounter tarantulas due to the fact that tarantulas spend their days hidden deep in their burrows.

What Do Curly Hair Tarantulas Eat?

Curly hair tarantulas eat crickets, grasshoppers, roaches, any insect that wanders by. But it will also eat small lizards, frogs and mice. They can go for months without eating including periods where they are dormant for months. For captive Curly hair tarantulas it is recommended to feed them 6-8 crickets a month in the warmer months and 1-2 crickets a month in the cooler months. When they are molting they seem to lose their appetite altogether so just give them some time and reintroduce food once a week.

What is the Conservation Status of Curly Hair Tarantulas?

Curly hair tarantulas are listed as a species of “Least Concern” by the IUCN. They seem to maintain a healthy population in Honduras, Nicaragua and Costa Rica.

Reproduction, Babies, and Lifespan

Male curly hairs reach sexual maturity around the age of 5-8 years. This is the time that they venture out away from their burrows in search of a mate. Their mating results in two possible outcomes, either they mate successfully and go on their way or they are eaten by the female! Sounds risky, but the system seems to work, seeing as curly hair tarantulas have a healthy population that continues to prosper.

When male Curly hair tarantulas reach maturity, somewhere between 5-8 years old, they leave their burrows in search of a mate. When they come across a female’s burrow they will tap their leg on the ground outside the burrow like knocking on the door to see if the female is receptive. If she is the male creates a sperm web where he deposits his sperm then transfers it to one of his pedipalps then transfers it to the female.

Female Curly hair tarantulas lay around 300-500 eggs each year. They create an egg sac by spinning a web around them to keep them safe. With a method termed “brooding” the female will turn the sac occasionally to make sure everything is even  The mother then keeps the sac deep in her burrow watching over the eggs. When the eggs hatch the mother keeps tabs on the offspring for a few weeks until they are ready to venture out on their own.

The life span of curly hair tarantulas is dependent on their gender. Females have been recorded to live more than 20 years whereas males live closer to 8-10 years. In the pet trade, females are preferred due to their long longevity.

Population

Curly hair tarantulas live underground in burrows in remote locations. This makes it difficult to tally an accurate population. The IUCN has them listed as “Least Concerned” so they seem to have a healthy population.
