__NOTOC__ |
|||
The '''North American Mountain Skink''' (''Plestiodon |
|||
callicephalus'') is a medium-sized member of the ''Plestiodon'' [[skink]]s, a kind of [[lizard]], living in [[North America]]. |
|||
==Taxonomy== |
|||
At least one [[herpetologist]] has considered the [[species]] a [[subspecies]] of ''[[Plestiodon tetragrammus]]'' under the scientific name ''P. tetragrammus callicephalus'', but the more common classification considers it a separate species based on differences in appearance and the distinct geographic distribution. |
|||
== Description == |
|||
The Mountain Skink is a medium-sized skink reaching a maximum length from snout to vent of about 7.5 cm (3 inches). Its body is olive to brown in color, with black stripes on the sides. On the head, it features a distinctive, roughly Y-shaped light line pattern, which gave rise to its scientific name: ''callicephalus'' is [[Greek language|Greek]] and means "beautiful head". |
|||
Like many other ''[[Plestiodon]]'', juvenile Mountain Skinks have a bright blue tail. However, contrary to most other species of this [[genus]], adults retain this color, although it does fade a little with age. |
|||
== Range == |
|||
The Mountain Skink occurs from southeastern [[Arizona]] and extreme southwestern |
|||
[[New Mexico]] southward to [[Nayarit]] and [[Jalisco]] in [[Mexico]]. |
|||
In the [[United States|U.S.]], the species is very localized. In New Mexico, Mountain Skinks are found only in the southern [[Peloncillo Mountains (Hidalgo County)]] of southwest [[Hidalgo County, New Mexico|Hidalgo County]]. It is known only from Geronimo Trail and Guadalupe Canyon, where it is uncommon in its limited habitat. In Arizona, Mountain Skink occurs in the [[Coronado National Forest]]. Throughout its range in [[Mexico]], the species seems secure, although many local populations may be jeopardized by habitat loss. |
|||
In New Mexico, the species is classified as "critically impaired". |
|||
== Habitat == |
|||
The Mountain Skink is found in a wide variety of habitat, ranging from sea level to nearly 2000 m (about 6560 ft). It prefers areas with abundant and well-rotted leaf litter, provinding cover and places for laying eggs. |
|||
''Plestiodon callicephalus'' is a terrestrial skink, spending most of its time foraging on the ground, hunting for small [[invertebrate]]s. It is a good burrower, burrowing its own den. |
