Coral Snake Information & Facts



Coral Snake Appearance: There are many varieties of coral snakes throughout the Americas, but we will address the USA snakes. The most common species in the United States have a universal red-yellow-black-yellow pattern. Not all coral snakes have the same color scheme, so it is important to be familiar with the snakes specific to your region. This snake is small in comparison to other venomous snakes in the United States. At its longest, an adult can measure around thirty inches. The colorful body is slender and lacks real variance in width. The head blends seamlessly into the body with no distinctive neck. The head of this species of coral snake is always black.

Coral Snake Habitat and Behavior: There are two types, the Eastern Coral Snake, and the Western Coral Snake. The Eastern is more common, but neither is seen often, because Coral snakes that live in either the southeastern or southwestern United States prefer wooded, marshy, and loose-soiled areas often under debris. They are very reclusive, staying in the safety of underground burrows or dens during the day and emerging in the evening and early morning to feed. Among their own kind, coral snakes are solitary, showing aggression even during breeding.


Unlike other venomous snakes, the coral snake has round pupils, a blunt head, and no heat sensing pits. Its venom sacks are not attached to the fangs but are adjacent to the teeth, permeating the puncture holes as the snake latches onto a victim. Contrary to common belief, the maximum amount of venom can be delivered without chewing; the venom delivery is related to the duration of time the snake is attached, not how many times it bites its prey. Multiple bites do facilitate quicker venom transfer, but do not necessarily affect the quantity.

Coral snake venom is neurotoxic, another fact which distinguishes it from other North American poisonous snakes. Neurotoxic venom affects the way the brain communicates with muscles, slurring speech, affecting movement, and ultimately ceasing cardiac or respiratory function. A bite from a coral snake can go without symptoms for as long as twelve hours.

Unfortunately, due to their bright colors, coral snakes are a favorite of children. Many of the reported bite cases are due to the curiosity of a young person who tried to pick up the reptile. For this reason, it is good that coral snakes are shy and rarely spotted. To avoid trouble, read more about the Snake Rhyme Poem, and information about the Coral Snake Look Alikes, such as the Scarlet Kingsnake, to find out what does a coral snake look like.

Infant coral snakes hatch from eggs laid by the female snake. Coral snakes do not give birth to live young like many of the other North American venomous snakes. Once born, coral snakes are seven inches long and are already at their full venomous potential.

Coral Snake Diet: Coral snakes are carnivorous and like a diet of other reptiles and snakes (even other coral snakes). It will occasionally feed on frogs.

What this means is that the ability of the nerves in the body to communicate with cells is shut off. If your brain cannot communicate to the heart that it needs to beat, the function will cease. Neurotoxic venom is only found in lethal doses in the coral snake out of the venomous snakes in North America. When the snake bites its victim, it will hold on to the adversary for as long as possible. This is because coral snakes do not have venom sacks attached to their fangs like vipers do. The coral snake’s venom is secreted into the wound as the snake holds on. The longer the animal is attached, the more venom is administered. Coral snake bites can go without symptoms for as long as twelve hours after exposure. Some people who are bitten believe they have encountered a milk snake and not a coral snake because no immediate signs are evident. Thankfully, despite the delayed onset of issues, no reported deaths from coral snakes have occurred since the development of an antivenin in 1960.

Coral snakes habitat Coral snakes live in the southeastern and southwestern United States, though there are other species of coral snakes around the world. They prefer wooded areas, marshes, or places with loose soil. Preferring to hunt in the evening or early morning, coral snakes remain in their dens for the majority of the day. For this reason they are rarely spotted by travelers. Unlike many other snakes, the coral snake is not bold and will try to flee a situation rather than stand its ground. If the animal feels harassed, however, it will strike without warning. The bite from a coral snake is not like the bite from a pit viper. Coral snakes will hold on to their victim, allowing the venom in their mouths to transfer into the wound. The longer the snake holds on, the more venom is put into the body. This substance is a neurotoxin and will eventually cease cardiac and pulmonary activity.
