NE Floridas Venomous Snakes
WHAT IS A SNAKE? A snake is a reptile without legs. A reptile usually has scales, lays eggs, breathes air, and doesnt spend much time taking care of its babies. It is also cold-blooded, which means that its body doesnt stay the same temperature all the time. (Our bodies stay at 98.6 F all day.) Snakes get very cold on winter days and very hot in the summer. Because of this, snakes usually stay in burrows during very hot and cold weather. A burrow is a hole in the ground where they can live.
WHAT DO SNAKES EAT? All snakes are carnivores (car-ni-vorz) or meat-eaters. Small snakes eat bugs and frogs. Larger ones eat fish, birds, mice, and rabbits. They use sharp teeth and strong muscles to catch the prey. If the prey animal is bigger than the snakes mouth, the snake can dislocate (unhinge) its bottom jaw to fit the big animal in.
WHAT IS VENOM? Venom is a poison the snake puts into its prey through its fangs (teeth). This either kills the prey animal or makes it so the prey cant move. Once venom gets into the prey, it is easy for the snake to eat it. The snakes on this page DO HAVE VENOM. Some venomous snakes have bright colors or patterns which can warn us. Rattlesnakes have rattles to warn away animals or people that might hurt them
Eastern Diamondback Rattlesnake (Crotalus adamanteus) is the largest snake native to North America, reaching 6 feet long. It has brown, black, and beige diamond marks on its back. This snake lives in forests near palmetto bushes. It makes its home in old animal burrows (holes in the ground). It is a good swimmer and can live near fresh or salt water. The eastern diamondback does NOT always rattle before it strikes.

Dusky Pigmy Rattlesnake (Sistrurus miliarius barbouri) is usually less than 1 ½ feet long and not even as thick as a grown-ups thumb. It is dark gray with black and brown patches. The rattle is very tiny and hard to see. The sound it makes is so small that it may sound like an insect buzz. This snake lives near marshes and ponds under palmetto bushes. A baby dusky is not much bigger than a quarter.
Florida Cottonmouth (Agkistrodon piscivorus conanti) is a thick-bodied(fat)water snake also called a Water Mocassin. It is usually between 2 and 4 feet long. When it is young, its light brown with black and olive patterns. As it gets older, black covers up the patterns, and it looks like an all-black snake. When its angry, it opens its mouth wide, showing the white inside. This snake does NOT have a rattle. Cottonmouths can be aggressive and may strike several times. They live near swamps, lakes, and ditches.
Eastern Coral Snakes (Micrurius fulvius fulvius) are skinny snakes about 2 feet long. They have rings of red, yellow, and black all along their bodies. Their noses are always black. They do not have long fangs and have to actually chew on you to get the venom in. Many snakes look like the coral snake. A rhyme about the order of the colored stripes helps you tell them apart, but dont get too close! Rhyme: Red and yellow kills a fellow. Red and black is safe for Jack. Coral snakes [venomous] have red and yellow touching; scarlet king snakes [non-venomous] have red and black.
