Plethodontinae
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]   |

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]   |

Batrachoseps Attenuatus
The California slender salamander (''Batrachoseps attenuatus'') is a lungless salamander Stebbins, Robert C. (2003). ''A Field Guide to Western Reptiles and Amphibians'', 3rd Edition. Houghton Mifflin Company, that is found primarily in coastal mountain areas of Northern California, United States as well as in a limited part of the western foothills of the Sierra Nevada, California, in patches of the northern Central Valley of California, and in extreme southwestern Oregon. This species resides primarily in a limited range within California as one of a handful quasi-endemic amphibians in the state. In 2001 Elizabeth L. Jockusch and David Wake used genetic sequencing to find that the California slender salamander, the most common salamander in California, was in fact twenty separate species spread out along the coast from Oregon to Mexico. Presently, the California slender salamander is viewed as one of the nineteen species of the genus ''Batrachoseps'', each of which is cha ...

Chiropterotriton
''Chiropterotriton'', also known as splayfoot salamanders or flat-footed salamanders, is a genus of salamanders in the family Plethodontidae. The genus is endemic to Mexico. ''Chiropterotriton'' are widely distributed in northern and eastern Mexico. They are an ecologically diverse group, occupying a range of habitats, including cloud forests, pine-oak forests, oak forests, and caves. They may be found in various microhabitats, such as arboreal bromeliad The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, ...s, rock crevices, caves, and terrestrial cover objects. Most species are superficially similar in their appearance, making species delimitation by purely morphological means difficult. However, molecular methods have aided description of new species.

Batrachoseps
''Batrachoseps'' is a genus of lungless salamanders (plethodontids) often called slender salamanders. They can be distinguished from other lungless salamanders by the four toes they have on each foot. Their genus name ''Batracho-seps'' means "frog-lizard", in reference to their projectile tongues. Diet and physiology The lungless salamanders, in addition to having no lungs, have long slender snake-shaped bodies with very small limbs that appear almost vestigial in several species. Their main diet consists of small insects, such as springtails, small bark beetles, crickets, young snails, mites, and spiders. Like all salamanders in this family, they have long frog-like projectile tongues which they use to grab their prey in a flash. Unlike all other amphibians (and birds, and lizards, and nearly all fish) mature red blood cells in species in the genus ''Batrachoseps'' have no nucleus, which is a trait that is only known to occur in mammals and certain species of antarctic fish. ...

Bolitoglossa
''Bolitoglossa'' is a genus of lungless salamanders, also called mushroom-tongued salamanders, tropical climbing salamanders, or web-footed salamanders, in the family Plethodontidae. Their range is between northern Mexico through Central America to Colombia, Venezuela, Ecuador, Peru, northeastern Brazil, and central Bolivia. Neotropical salamanders of the ''Bolitoglossa'' make up the largest genus in the order Caudata, consisting of approximately one-fifth of all known species of salamanders. Adult salamanders range anywhere from 45mm to 200mm in length depending on their specific species. They are notorious for their ability to project their tongue at prey items, as indicated from their name. They are also known for their webbed feet, having significantly more webbing than any other species outside their genus with the exception of the cave-dwelling Mexican bolitoglossine ''Chiropterotriton magnipes''. Although webbed feet are a common characteristic of these salamanders, only ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
