The common coral snake likes to burrow in rotting logs or under soil, leaves or rocks in dry forests. It can also be found in marshy places. An adult eastern coral snake is two to three feet long with smooth scales. There are 15 rows of these scales in the upper part of the snake’s body. Male snakes have longer tails, but females are longer overall.
Despite the potency of its venom, the snake s fairly docile, at least to humans. It will, however, attack and even eat other coral snakes. It also eats other types of snakes, fish, birds, frogs, insects and lizards. Its venom, which is a neurotoxin, makes quick work of its prey. The coral snake resembles other, harmless snakes, such as the scarlet snake or scarlet kingsnake. It may be better to say that these snakes resemble the coral snake. Mimicking the color of the venomous snake may cause predators to leave these harmless snakes alone. This is called Batesian mimicry. One way to tell a scarlet kingsnake from the eastern coral snake is the saying, “Red on yellow, kill a fellow; red on black, venom lack.”
After mating in June, the female is gravid for about 37 days. She’ll then lay five to seven eggs, which makes the snake the only egg-laying venomous snake in North America. The young hatch about two months after the eggs are laid. They’re about 7 to 9 inches long
When in captivity, the snake lives for about 7 years. Its venom is used to make antidotes for snake bites and is being studied for possible use for other diseases such as AIDS.
As a neurotoxin, the snake’s venom destroys the ability of the nerves to communicate with each other. After a few hours, the person starts experiencing such symptoms as drooping eyelids, difficulty in swallowing, headache, stomach pain, paralysis, and convulsions. They may also go into shock. The patient should be kept quiet and taken to the hospital. Unlike in the movies, the snake bite shouldn’t be cut into and suctioned out. The patient shouldn’t be given a tourniquet, a cold compress, or have the affected area raised above their heart.
