Xantusia Vigilis
The desert night lizard (''Xantusia vigilis'') is a night lizard native to the Southern California Eastern Sierra and the San Gabriel Mountains into Baja California, southern Nevada, southwestern Utah and extreme western areas of Arizona. Description The desert night lizard attains a snout-to-vent length (SVL) of with a tail roughly the same length. The lizard's coloring is usually grey, yellow-brownish, or olive. Despite their name, night lizards are active during the day. They are known to easily change their color, from light olive (usually during the evening) to dark brown during the day. It is a good climber and usually eats termites, small insects, spiders and other arthropods. The desert night lizard is small for a reptile, with the average adult female at 80 mm in total length and 1.3 g in weight. The average adult male ''Xantusia vigilis'' is 65mm in total length and 1.1 g in weight. Male desert night lizards are distinguishable from females as they are lighter ...

Xantusia Gilberti
''Xantusia gilberti'', also known commonly as the Baja California night lizard and ''la nocturna de Baja California'' in Mexican Spanish, is a species of small lizard in the family Xantusiidae.

There are nine femoral pores on one leg and eight on the other. Van Denburgh (1895). Reproduction ''X. gilberti'' is viviparous Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the m ....

Xantusia Bezyi
Bezy's night lizard (''Xantusia bezyi'') is a species of lizard in the family Xantusiidae. The species is endemic to Arizona. Etymology Bezy's night lizard is named after noted American herpetologist Robert Lee Bezy (born 1941). Geographic range ''X. bezyi'' is found in central Arizona.

Xantusia Arizonae
The Arizona night lizard (''Xantusia arizonae'') is a species of small smooth-skinned gray-brown lizards with dark spots that sometimes form partial lines down the back. The lizard has a slightly flattened head. The scales of the underside and tail are larger than those of the upper side. The lizard grows to a length of 6 to 10 cm.Bezy, Robert L"The Night Lizards (''Xantusia'') of Arizona" . Sonoran Herpetologist. Retrieved 30 December 2011Arizona Game and Fish Department. 2003 "Xantusia arizonae". Unpublished abstract compiled and edited by the Heritage Data Management System, Arizona Game and Fish Department, Phoenix, AZ. 1-2 pp. Despite its name, the Arizona night lizard is primarily active during the day. The lizard's range extends across west-central Arizona. It is usually found in rock crevices or under plant debris. Its diet consists of insects and spiders.

Xantusia Gracilis
The sandstone night lizard (''Xantusia gracilis'') is a species of night lizard. Prior to 2005, it was considered a subspecies of the granite night lizard, ''Xantusia henshawi''. The physical difference is that the sandstone night lizard has lighter coloration. Range The sandstone night lizard is extremely limited geographically; it is known only to the Truckhaven Rocks in the Colorado Desert, at Anza-Borrego Desert State Park in eastern San Diego County, California. Description The lizard is very secretive using small burrows and sandstone or siltstone Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, p ... for cover.

Night Lizards
Night lizards (family Xantusiidae) are a group of small scincomorph lizards, averaging from less than to over snout–vent length. Most species are viviparous (live-bearing), with the exception of those in the genus '' Cricosaura''. The family has only three living genera, with approximately 34 living species. The genera are divided by geographic range: ''Xantusia'' in southwestern North America and Baja California, '' Cricosaura'' in Cuba, and '' Lepidophyma'', the most populous night lizard genus, in Central America. Three fossil genera are also known: ''Catactegenys'', '' Palepidophyma'', '' Palaeoxantusia''. Biology Night lizards were originally thought to be nocturnal because of their secretive lifestyle, but they are at least in some cases diurnal. Night lizards have evolved to live in very narrow environmental niches—"microhabitat specialization"—such as rock crevices or damp logs, and may spend their entire life under the same cover. Physically, night lizard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Henry Gilbert
Charles Henry Gilbert (December 5, 1859 in Rockford, Illinois – April 20, 1928 in Palo Alto, California) was a pioneer ichthyologist and Fisheries science, fishery biologist of particular significance to natural history of the western United States. He collected and studied fishes from Central America north to Alaska and described many new species. Later he became an expert on Pacific salmon and was a noted conservation movement, conservationist of the Pacific Northwest. He is considered by many as the intellectual founder of American fisheries biology. He was one of the 22 "pioneer professors" (founding faculty) of Stanford University. Early life and education Born in Rockford, Illinois, Gilbert spent his early years in Indianapolis, Indiana, where he came under the influence of his high school teacher, David Starr Jordan (1851‒1931). When Jordan became Professor of Natural History at Butler University in Indianapolis, Gilbert followed and received his B.A. degree in 187 ...

Southwestern United States
The Southwestern United States, also known as the American Southwest or simply the Southwest, is a geographic and cultural region of the United States that generally includes Arizona, New Mexico, and adjacent portions of California, Colorado, Nevada, Oklahoma, Texas, and Utah. The largest cities by metropolitan area are Phoenix, Las Vegas, El Paso, Albuquerque, and Tucson. Prior to 1848, in the historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas, settlement was almost non-existent outside of Nuevo México's Pueblos and Spanish or Mexican municipalities. Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854. While the region's boundaries are not officially defined, there have been attempts to do so. One such definition is from the Mojave Desert in California in the west (117° west longitude) t ...
