The Oaxacan Small-Headed Rattlesnake, also known as Gloyd's Small-Headed Rattlesnake, is a small species of snake found in the highlands of southern Mexico. Oaxacan Small-Headed Rattlesnakes are often dark grey, sometimes purple or brownish, with jagged blotches of a darker color along the sides. A distinguishing feature of this snake is a black streak above the eye and a white streak below.
It occupies elevations from 1,000 - 3,000m above sea level, and can be found in a variety of habitats from tropical cloud forest, to dry pine-oak forests and even semi-arid deserts. This species is active during the day. It is both an ambush predator and a generalist, targeting lizards, toads and small mammals.
This subspecies is named after American Herpetologist Howard K. Gloyd.
