Description
The Texas lyre snake is a medium-sized snake, attaining a total length (including tail) of approximately 1 meter (39 inches) at adult size. It is brown, tan or gray with 17-24 dark brown blotches down the back. It has large eyes with vertical pupils. The common name, "lyre snake", refers to a distinctive V-shaped pattern on the head which resembles the shape of a lyre. However, this particular subspecies (T. b. vilkinsonii ) has no V mark on the head.
Range & habitat
T. vilkinsonii is found in the United States in the Big Bend region of Texas and southern New Mexico, and in Mexico in northeastern Chihuahua.

What it does
Lyre snakes of the genus Trimorphodon are nocturnal, spending most of their time hiding in rock crevices, emerging to feed mainly on lizards, and also on small rodents, frogs, bats and birds. Their venom is not considered to be harmful to humans. Also, if their venom is not fatal to their prey, they may kill by constriction.

In human culture
The epithet vilkinsonii is in honor of amateur American naturalist Edward Wilkinson, who collected the first specimen near the city of Chihuahua.
