Description

Family Colubridae

The family Colubridae, which includes the kingsnakes (Lampropeltis spp. ), is the largest, most widespread, and diverse family of snakes , with few physical characteristics universal among all species. The family contains 70 percent of the known species of snakes, with more than 1700 species worldwide (Pough et al. 1998). Although some colubrids are dangerously venomous , most are harmless to humans. [1]

Habitat

Ecology: This snake occurs in a wide range of habitats , from desert flats, dry grasslands, and tropical lowlands to pine-oak habitats and cloud forest in mountains; in the southwestern United States it is often in the vicinity of permanent and intermittent streams , spring seepages, and irrigation canals, usually in canyons , foothills, or mountains (Stebbins 2003). It inhabits rocky hillsides and limestone ledges, and wooded ravines and cedar brakes, in the Texas Hill Country (Tennant 1984). In Mexico, habitats include tropical barrancas, thorny scrub forest, tropical deciduous forest, and upper arid or mixed boreal-tropical cloud forest (Rossman et al. 1996). This snake wanders far from water into adjacent grassland, desert, woodland, and shrubland, but mostly it is restricted to the vicinity of consistent water sources in the arid southwest (Jones 1990).[2].
