	Ixalotriton Niger ''Ixalotriton niger'', the black jumping salamander, is a species of salamander in the family Plethodontidae. It is endemic to Mexico. Its natural habitats are subtropical or tropical moist montane forests and rocky areas and it is threatened by habitat loss. Description ''Ixalotriton niger'' is a long, slender salamander with a wide head, protuberant eyes, long limbs, large hands and feet and a long, gradually tapering tail. It grows to a total length of nearly and is a glossy black colour. At night it changes to a chocolate brown colour. The snout may have a small white patch and the tips or the toes are red, perhaps because of an absence of pigment allowing the vascular tissue below to show through. Distribution and habitat ''Ixalotriton niger'' is found at about above sea level on the Atlantic side of the Northern Highland Mountains in Chiapas State in south west Mexico. The area where it is endemic is composed of fissured limestone crags clothed in an evergreen forest ric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Ixalotriton Parva ''Ixalotriton parva'', the dwarf false brook salamander, is a species of salamander in the family Plethodontidae. It is endemic to a small mountainous area of Mexico where its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss. There is some doubt whether this species should be classified as ''Pseudoeurycea parva'' or ''Ixalotriton parva''. Description The dwarf false brook salamander is small with a broad head, small nostrils, protruding eyes and slender body. It grows to a length of about , half of which is the tail. It is a greyish-brown colour with a pale brown stripe running along the ridge of the back and a few whitish spots on the tail, which is prehensile. In appearance it is very similar to '' Pseudoeurycea praecellens''. Distribution and habitat The dwarf false brook salamander is endemic to the Cerro Baul Mountains in the eastern part of Oaxaca State, Mexico at an altitude of about above sea level. It lives in virgin clo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Plethodontidae Plethodontidae, or lungless salamanders, are a family of salamanders. Most species are native to the Western Hemisphere, from British Columbia to Brazil, although a few species are found in Sardinia, Europe south of the Alps, and South Korea. In terms of number of species, they are by far the largest group of salamanders. Biology Adult lungless salamanders have four limbs, with four toes on the fore limbs, and usually with five on the hind limbs. Within many species, mating and reproduction occur solely on land. Accordingly, many species also lack an aquatic larval stage, a phenomenon known as direct development in which the offspring hatch as fully-formed, miniature adults. Direct development is correlated with changes in the developmental characteristics of plethodontids compared to other families of salamanders including increases in egg size and duration of embryonic development. Additionally, the evolutionary loss of the aquatic larval stage is related to a diminishing dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Salamander Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela. Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders rarely have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating lost lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
