Florida is home to alligators, crocodiles, gigantic invasive pythons, panthers, and some of the most shark-infested waters in the world. So it’s no surprise people are curious just what are the most dangerous animals in the state. Let’s dive in to see everything from gigantic reptiles to venomous insects you need to be aware of when exploring Florida’s wilderness!

Are crocodiles and alligators the deadliest animals in Florida?

“Don’t worry the alligators are just like squirrels here!”

Um, I don’t think so! Some locals are used to cohabitating with alligators and crocodiles while visitors may be more leery. With the abundance of lakes, swamps, and the Everglades these reptiles are found throughout the state. In fact, it’s estimated that Florida’s alligator population stands at about 1.3 million. while there are about 2,000 crocodiles in the Everglades.

According to the Florida Fish and Wildlife Conservation Commission there were around six documented bites a year between 1971 and 1986, and that has increased to an average of ten per year between  1987 and 2017. Although fatalities are extremely rare there have been 25 recorded fatalities due to alligator attacks in Florida since 1948.

One of the most recent deaths in Florida was this past summer over the 4th of July weekend, 2021. A woman was found dead in a retention pond near Tampa, FL, with her family stating that she often swam in that pond. Compared to the number of worldwide alligator/crocodile deaths, Florida is extremely safe, especially if a few rules are followed to remain safe such as staying out of the water in known alligator territory and abiding by posted restrictions. Across the world, there are an average of 1,000 crocodile inflicted deaths annually, with many of these occurring in countries with sparse access to emergency healthcare.

How dangerous are the venomous snakes in Florida?

Worldwide the average number of snake-related deaths is at least 50,000 per year! That number seems astronomical, but it is the reality. Here in the United States, we have access to antivenom and although we do have species such as timber rattlers and cottonmouths, these are not the most venomous snakes in the world.

Internationally, the “Big 4” snakes are responsible for an estimated 75% of snakebite fatalities. These snakes include the Russell’s viper, common krait, Indian cobra, and saw-scaled viper. Each of these snakes lives in India where they come into contact with rapidly expanding urban areas with large populations.

In the US there are a reported 7,000-8,000 venomous snake bites a year but only 5 of those result in death. The number of kids bitten by snakes is much higher in Florida and Texas, in part due to the number of snakes in each state.

Florida has six venomous snakes within its borders: the eastern diamondback rattlesnake, timber rattlesnake, pygmy rattlesnake, cottonmouth, copperhead, and eastern coral snake. Recent snake bite deaths included a 2014 incident where a 4-year-old was bitten by a timber rattlesnake and two deaths in 2005 from a coral and eastern diamondback rattlesnake. Overall, most recorded snakebite deaths in Florida have come from eastern diamondbacks.

There are also 3 scorpions found in Florida that can produce painful stings but are generally not fatal. Florida is also home to the southern black widow and brown recluse, both of which have venom that can produce extremely painful bites.

What about other snakes, like the Burmese python, are these the deadliest?

Burmese pythons are not native to Florida but they do live here. Talk about big snakes, these are huge! They can grow to be 6-9 feet long with the longest one recorded in Florida reaching 18 feet! And they are not skinny little snakes, they are thick with some as thick around as a telephone pole. They are not venomous but may bite in self-defense.

Pythons are constrictors and kill their prey by wrapping around them until they can no longer breath, then releasing them and eating them whole. According to the United States Geological Survey, there have not been any fatalities resulting from Burmese Pythons in Florida. Pets, like dogs and cats, have been victims of these giant snakes and they are considered an invasive species. If you see one you should report the sighting and get to safety as soon as possible.

What other deadly animals are there on land in Florida?

The state animal is the Florida panther. These mountain lions can grow to be 60-160lbs and are long at 5-7 feet. Because Florida panthers are endangered, its extremely rare that humans come into contact with them. They are listed as endangered and are protected in Florida, with 120-230 left in the wild. If you want a safe way to see one of these rare animals you can visit the Ellie Schiller Homosassa Springs Wildlife State Park.

What deadly animals are in the waters surrounding Florida?

Florida is a peninsula with the Atlantic Ocean to the east and the Gulf of Mexico to the west. As soon as you think of dangerous ocean animals you probably think of sharks. But what about jellyfish? Let’s look at some of the dangerous marine animals in Florida:

  • Sharks: There are Great White sharks that live off the coast of Florida, both in the Atlantic and the Gulf. Shark attacks, in general, are pretty rare but with the number of beaches in Florida and the number of beachgoers, it should not be a surprise that Florida has the highest number of shark attacks in the US. In 2020 Florida topped the list of shark bites with 16, Hawaii came in second place with 5. Half of those attacks in Florida were in Volusia County. Most often sharks mistake surfers for seals and attack them thinking they are dinner. Globally there were only 11 shark-related fatalities in 2021, so statistically, it is highly unlikely to die from a shark.
  • Jellyfish: Box jellyfish are known to be the deadliest jellyfish with venomous stingers that can cause a person to go into shock or have a heart attack. They are clear (which doesn’t help spotting them in the ocean) and can grow to be 10 feet long. There are no known deaths from jellyfish in Florida but worldwide there is an average of 40 per year. Other jellyfish species are less venomous but still provide a painful sting. Over a period of three days in 2018, 800 people were stung by jellyfish along the central Florida coast with a large group of moon jellyfish showing up. A spokesperson said that once or twice a year there is a high incidence of jellyfish due to the currents. Beachgoers can be aware of posted flags on the beach indicating certain risks like high tides or dangerous marine life, thus limiting their risks so they can enjoy the beautiful Florida beaches year-round.
