Quick Answer

Florida has 44 species of snakes, of which only 6 are venomous. The venomous species are: Eastern Diamondback Rattlesnake (largest, up to 6 ft), Timber Rattlesnake (north Florida), Pygmy Rattlesnake (small, statewide), Copperhead (panhandle only), Cottonmouth/Water Moccasin (statewide near water), and Coral Snake (statewide, secretive). Non-venomous species include the Black Racer (fast, black), Corn Snake (orange/brown with blotches), and Yellow Rat Snake (yellow, climbs trees).

Florida Snake Identification Guide

Coral Snake Rhyme: Red Touch Yellow

The coral snake has a distinctive color pattern: red bands bordered by yellow bands. The non-venomous scarlet kingsnake has a similar pattern but with red bands bordered by black bands. The rhyme goes: "Red touch yellow, kill a fellow; red touch black, venom lack." This works for Florida but not for all regions.
