The coastal lyra snake ( Trimorphodon biscutatus ) is a rather weakly poisonous representative of the snakes (Serpentes). The snake, up to 1.2 meters long, is characterized by a V-shaped head markings, light brown to gray coloring, dark saddle spots with a light center and vertical pupils. Its range extends from Mexico to Guatemala and Costa Rica , where it inhabits rocky areas, pine forests and desert-like areas up to 3500 meters above sea level. This nocturnal ground dweller feeds mainly on lizards and other snakes, but small mammals and birds are not spurned either. It lays eggs, unlike many other snakes, which are viviparous .
There are five subspecies :
- Trimorphodon biscutatus biscutatus ( Duméril & Bibron , 1854)
- Trimorphodon biscutatus lambda ( Cope , 1886)
- Trimorphodon biscutatus lyrophanes ( Cope , 1860)
- Trimorphodon biscutatus quadruplex ( Smith , 1941)
- Trimorphodon biscutatus vilkinsonii ( Cope , 1886)
The poison of the coastal lyre snake is not potent enough to seriously endanger humans.
