Eastern Garter Snake (Thamnophis sirtalis sirtalis) photographed in Brevard County, Florida. The Eastern garter snake reaches a size of 20 to 28 inches, females are normally longer than males. However, the maximum recorded specimen had a length of 48.7 inches.
Eastern Garter Snakes are actually venomous since they have toxins in their saliva with effects similar to that of snake venom. However their bite is considered harmless and not dangerous to humans, producing only a mild reaction in humans. But their toxic saliva can be quite deadly to their small prey. Even so unlike most venomous snakes that have long and hollow fangs to deliver their venom garter snakes need to “chew” into their prey, so the venom can enter the prey’s bloodstream.
