Florida’s Venomous Snakes
The same warm climate and beautiful outdoor scenery that brings retirees and visitors to Fla. every year also attract outdoor reptiles like snakes. Whether you’re a full-time Floridian basking in the state’s beauty regularly or visiting for a short spell, keep an eye out for the most venomous snakes that occupy the state.
Florida’s Venomous Snakes
Most snakes in the state are non-venomous, but the six venomous snakes on the list below are the exception. These snakes are typically found in less populated areas but have been known to appear in human-occupied zones. It is a good idea to recognize them all and know when to stay away!
1- Florida Cottonmouth
Reaching lengths of up to 6-foot long, the Florida Cottonmouth is the most venomous snake in the state. Referred to as the green-tailed moccasin, the Cottonmouth is found in swampy regions, along the water, and wooded areas. The snake produces venom that damages the tissues. Death is rare, although bites in humans often require amputations. The color can range from a banded olive green or dark brown to a jet black that hides the bands. Its head is noticeably spade-shaped and larger and thicker than it’s neck.
2- Timber Rattlesnake
The Timber Rattlesnake is found in many U.S. states, including Florida. The snake is found in forests and rugged terrains more often than other habitats and prefers slopes leading to creeks through hardwood forests. Although it is not as aggressive as an Eastern Diamondback, bites from a Timber Rattlesnake can be lethal if not quickly treated.
3- Eastern Diamondback Rattlesnake
The Eastern Diamondback Rattlesnake is the heaviest venomous snake in the United States. The snake is the largest of the rattlesnake species, reaching a maximum length of 8.25-foot long. This snake lives in marshes and swamps, dry pine forests, and in numerous other habitats, although its poor climbing skills and pristine swimming skills keep the snake near water. Eastern Diamondback Rattlesnakes have long fangs and a large body, making it one of the most feared snakes in the state; around 10% – 30% of all Eastern Diamondback Rattlesnake bites are lethal.
4- Eastern Coral Snake
The Eastern Coral Snake is easily identified by its colorful body with shades of orange, yellow and black. The snake prefers tropical areas of the state. It is found in all elevations but thankfully is quite shy and prefers to remain secretive. Bites from the Eastern Coral Snake can be fatal but rarely cause mortality. Although the venom is strong enough to kill several humans at once, the low bite-rate and secrecy of the snake keep people safe more often than not. Please note that there are two other snakes in Florida which look similar to the Eastern Coral Snake but are harmless – the Scarlet Kingsnake and Scarlet Snake. Luckily, it is easy to distinguish between them as the Eastern Coral Snake has a black snout while the other two have red snouts. All three are beneficial to the environment and should not be harmed if seen.
5- Dusky Pygmy Rattlesnake
The Dusky Pygmy Rattlesnake is scattered throughout the state, living everywhere from swamps to along bodies of water to prairies. The snake is aggressive and protects itself against all threats, leading to snake bites. Most bites from the Dusky Pygmy Rattlesnake are very painful but non-lethal. Many require limb amputation. This snake consumed small animals for the biggest portion of its diet.
6- Southern Copperhead
The Southern Copperhead lives in wooded and mixed pasture areas in all areas of the state. It is most common during the spring and late fall but lives nocturnally during the summer months. The snake grows to lengths of about 24 to 26-inches. Copperhead snakes are among the most feared species of snakes. The Southern Copperhead has short fangs that prevent the venom from causing fatal bites in most cases.
