Physical characteristics: With their brownish pink to dark brown coloration, Texas blind snakes look much like earthworms, except that the snakes have noticeable scales and lack the worm's segments. The snakes have a lighter colored, sometimes almost white, underside. Also known as Texas thread snakes, they have a long, thin body and a small head with eyes that appear as little more than tiny dark spots. Adults range from 2.6 to 10.7 inches (6.6 to 27 centimeters) long. The tail is short, just 5 to 6 percent of total body length, and has a spine at the end.

Geographic range: Texas blind snakes are found in the southwestern United States and northeastern Mexico.

Habitat: Also known as a Texas worm snake, the Texas blind snake spends much of its time in the dirt, under rocks, or in some other hiding place. It can live in dry areas, including deserts and rocky mountainsides, but often chooses a spot near a water source.

Diet: Texas blind snakes most often eat ant larvae and pupae and termites, but they sometimes eat other insects and spiders. They always eat ant larvae and pupae whole, but they often refuse to eat the heads of termites and sometimes only chew the juices out of the back portion of the termite. Once in a while, a small owl known as a screech owl will swoop down to snatch a Texas blind snake and, keeping it alive, bring it back to its nest. There, the snake cleans out the nest by eating small invertebrates that might otherwise nibble on the owl.

Behavior and reproduction: Texas blind snakes live mainly underground but sometimes crawl out of their burrows at night or after a rain downpour. They are not especially good at slithering above ground and sometimes jab the tail spine into the ground to push off. Males and females group together in the spring for the mating season. The female lays two to seven eggs in June or July and then coils around them. Often, several females lay their eggs near one another. The eggs hatch in late summer into baby snakes about 2.6 to 3 inches (6.6 to 7.6 centimeters) long.

Texas blind snakes and people: Texas blind snakes and people rarely encounter one another.

Conservation status: This species is not listed as endangered or threatened. ∎

Interesting that Kelvin found a Blind Snake in Bexar Co, I am also in San Antonio. My cat found the snake some time before I did though, it was dead when I found it.

Very interesting looking creature though.

I am constantly finding Texas Blind Snakes in my home. I have found them in the bathroom, in the kitchen sink, in the living room and of course in my yard. I didn't know what they were, but I was glad to find that they were harmless. I always set them free when I find them in my home.

I found a Texas blind snake in Hudson, Florida, located on Florida's central Gulf coast. It has three head scales and is about five inches long. I have photos if you are interested.

I found a pinkish-brownish blind snake in my yard this afternoon. I live in Bexar County (San Antonio). I'm keeping it in a glass bowl for now. I'm not sure what to do with it.

They eat termites so if you find them in your home, you should have your home inspected for termites... we used to play with these when we were kids OH so long ago. Neat little guys, aren't they. They just found the world's smallest relative of our Texas "giant" worm snake in Barbados -

This is the third blind snake my cat's smuggled into the house. Fortunately, it was able to exit away from the clutches of a playful cat and back outside in one piece. Phew!

I am in a children's literature school and the next lesson is nonfiction. I saw for the first time the blind snake on my property this year and thought it would make an interesting article for children. The part about the owl using it to clean its next was a priceless piece of information to use in the article. You said this information is licenced would you allow me to use your information for my article?

We have an abundance of these little critters ever year at the beginning of summer. The kiddos and cats have a play-day--the kids rescuing the snakes from the cats! We live in North-Central Texas.
