Anacondas are not aggressive but they are defensive if they feel threatened.
Anacondas are apex predators and are much more likely to avoid contact with humans than to attack them.
Anacondas rarely attack or bite humans unless they are feeling threatened or are provoked or cannot get away and anacondas don't see humans as prey and tend to avoid them instead of attacking them.
Anacondas are also constrictors and not poisonous or venomous which means they wrap around and constrict and suffocate their prey to kill them.
Green anacondas are among the largest snakes in the world and are also an invasive species of snake in Florida and although there have been some sightings and even captures of green anacondas, there is also no established breeding population of anacondas in the Everglades.
Green anacondas are native to South America and have been introduced to Florida, likely through the pet trade.
If you are attacked by an Anaconda, do not run.
Lie flat on the ground.
Tuck in your chin.
And then the Anaconda will often just come and begin to nudge and will climb about your body.
Do not panic.
However if you're not in too close of proximity or can do so you should slowly back away from the Anaconda and other snakes and they will often leave you alone.
