Leptotyphlops Humilis is a scientific name, which refers to a species of snake known as the western threadsnake. Other synonyms for this tiny serpent include the slender blind snake, the small-banded blind snake, and the thread snake. These snakes grow to be less than a foot long and are commonly found in North and Central America. They are unique in that they do not have any hind limbs, but rather move using a serpentine motion. The western threadsnake is an important part of its ecosystem, preying on small insects and other invertebrates. While not particularly well-known, this species of snake plays an important role in maintaining the balance of its environment.
