The coloration of juveniles is the same as described for adults, and the tip of the tail of newborns ends in a “button”, which is the first segment of the future rattle.
Eastern Diamond-backed Rattlesnakes are found throughout Florida and in every county.
They also occur on many nearshore islands including many of the Florida Keys and several islands in the Gulf of Mexico in Levy (e.g., Cedar Keys) and Franklin (e.g., Dog, St. George, and St. Vincent islands) counties.
VENOMOUS The Eastern Diamond-backed Rattlesnake is a large and impressive snake, and bites can be very dangerous to people and pets.
The victim should seek immediate medical care from a physician or hospital experienced in treating snakebites.
Eastern Diamond-backed Rattlesnakes are not aggressive and avoid direct contact with people and pets.
Most bites occur when the snakes are intentionally molested or accidentally stepped on. This is a snake that should be simply left alone and not bothered.
Timber Rattlesnake (Crotalus horridus) Venomous The Timber Rattlesnake has black chevron-like crossbands, a reddish stripe down the middle of its back, and a black tail.
This is the only other rattlesnake with which an Eastern Diamond-backed Rattlesnake might be confused in Florida.
