Texas Coral Snake vs Milk Snake

There are several snakes that mimic the appearance of the Texas coral snake. Just think. Having an appearance very similar to the venomous Texas coral snake gives a non-venomous snake a sneaky way to avoid predators! Predators know instinctively that a brightly colored snake is likely to have venom.

One of those mimics aka lookalike snakes is the Central Plains milk snake. Studying the similarities and differences between these two snakes makes it a little easier to tell them apart.

Texas coral snakes and milk snakes are both found in Texas as well as in Arkansas, Louisiana, and northern Mexico. In addition, they share the same type of forest, grassland, and rocky habitat. At first glance, the colorful bands of the Texas coral snake and the milk snake look about the same. But the differences in color, pattern, and size can help differentiate a venomous Texas coral snake from a non-venomous milk snake.

The main difference in their appearance is the Texas coral snake has a pattern of black, red, and yellow. Its red and yellow bands touch. Alternatively, a milk snake has yellow, black, and red bands. Its yellow and black bands touch. Remember the old rhyme? Red and yellow kill a fellow, red on black friend of Jack. So, when yellow and red bands touch, you’re looking at a Texas coral snake capable of delivering venom.

The bands of a Texas coral snake continue all the way around its belly while a milk snake has a belly with a white and black checkered pattern.

Another subtle difference between a Texas coral snake and a milk snake is a Texas coral snake’s head is more rounded than its lookalike.

Texas Coral Snake Venom: How Dangerous Are They?

The Texas coral snake is venomous and can be dangerous to humans. It’s true that this snake is known for having the second most powerful venom in the world. (The black mamba takes first place in that contest.) However, the Texas coral snake is not aggressive. Plus, when this snake issues a bite to a human, it doesn’t inject a large amount of venom.

The small mouth along with the short, fixed fangs of a Texas coral snake prevent it from firmly biting into a human’s tough skin. This is why a bite from a Texas coral snake is not very painful. So, it doesn’t give a strong bite with plenty of venom in it like a rattlesnake. But any bite from this snake must always be taken seriously.

The first thing to do if someone gets a bite from this snake is to call an ambulance. Next, get the person to sit quietly in the shade and move as little as possible while waiting for help. Keep the injured area below the level of the person’s heart.

Today, there is an antivenom available to treat the bite of a Texas coral snake. In fact, since 1960 there have been no reported deaths from the bite of a Texas coral snake. But remember, receiving a bite from this snake means you should get to a hospital as soon as possible.

Texas Coral Snake Behavior and Humans

Texas coral snakes are described as shy and secretive. If they encounter a person in the woods or a grassland, this snake is very likely to slither away to find a place to hide.

Most bites from this snake are a result of an individual trying to pick up the snake or otherwise interact with it.

Texas Coral Snake Reproduction

The female Texas coral snake is oviparous–it lays a clutch of eggs, usually 3-12, usually underground or in leaves or soil. They typically lay them in June, and the eggs hatch in September. Coral snake hatchlings typically measure from 6.5 inches to 9.5 inches.
