The Typhlopidae (Typhlopidae) is a species of blind snakes that is tiny, only 20cm long.
The name of this snake comes from its appearance which is very similar to earthworms. In fact, they are often mistaken for worms.

The distinguishing feature of worm snakes from earthworms is that they are shiny black, and when viewed under the light, their skin will shine, they have scales and are not segmented. In particular, the tongue of worm snakes is also a forked tongue, typical of snakes.
Worm snakes live in places with lots of rotten wood and damp ground, near ant nests, termite nests, and places with temperate climates.

Folklore has it that the worm snake is extremely poisonous, and that a bite is certain to kill. But in reality, the worm snake's mouth is too small and has no fangs, nor is it venomous, so it cannot bite humans. It does not need to hunt, and its main food is ant eggs and termite eggs.
The eyesight of the worm snake is completely impaired because it lives underground. The eyes of the worm snake cannot see and so they mainly use their tongues to feel their way, “taste” the air and assess humidity, air movement, the smell of other creatures and where food is.

Worm snakes are asexual. All worm snakes found in the wild are female, there are no males.
Earthworms dig the soil to make it looser, more nutritious and airy, which is beneficial for plants, so they are useful animals for humans.
