Salamandridae
Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves. Most species of Salamandridae have moveable eyelids but lack lacrimal glands. Nearly all salamandrids produce a potent toxin in their skin, with some species being deadly to many other animal species. With a few exceptions, salamandrids have patterns of bright and contrasting colours, most of these are to warn potential predators of their toxicity. They have four well-developed limbs, with four toes on the fore limbs, and (in most cases) five toes on the hind limbs. They vary from in length. Many species within this family reproduce by method of internal fertilization. Additionally, there are many species-specific courtship rituals that males perform ...

Lyciasalamandra
''Lyciasalamandra'' is a genus of salamanders in the family Salamandridae. They are native to southwestern coast of Turkey and nearby Aegean Islands (Greece). As of early 2018, all species in the genus are threatened. The common name Lycian salamanders has been coined for them. Species ''Lyciasalamandra'' contains seven recognized species: Molecular data suggest that some recently described species (''Lyciasalamandra irfani'', ''Lyciasalamandra arikani'', and ''Lyciasalamandra yehudahi''), which as of early 2018 are still listed by the AmphibiaWeb, should be considered as subspecies of ''Lyciasalamandra billae''. Reproduction All ''Lyciasalamandra'' species are viviparous, as are four species of ''Salamandra ''Salamandra'' is a genus of seven species of salamanders localized in central and southern Europe, Northern Africa, and western Asia.

Triturus
''Triturus'' is a genus of newts comprising the crested and the marbled newts, which are found from Great Britain through most of continental Europe to westernmost Siberia, Anatolia, and the Caspian Sea region. Their English names refer to their appearance: marbled newts have a green–black colour pattern, while the males of crested newts, which are dark brown with a yellow or orange underside, develop a conspicuous jagged seam on their back and tail during their breeding phase. Crested and marbled newts live and breed in vegetation-rich ponds or similar aquatic habitats for two to six months and usually spend the rest of the year in shady, protection-rich land habitats close to their breeding sites. Males court females with a ritualised courtship display, display, ending in the deposition of a spermatophore that is picked up by the female. After fertilisation, a female lays 200–400 eggs, folding them individually into leaves of water plants. Larvae develop over two to four m ...

Euproctus
''Euproctus'', the European mountain salamanders, is a genus of salamanders in the family Salamandridae from Sardinia and Corsica. Species There are two species: The Pyrenean brook salamander used to be included in this genus as ''Euproctus asper'', but was moved to ''Calotriton'' in 2005. Its superficial similarity with ''Euproctus'' likely represents convergent evolution Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time.

Paramesotriton
''Paramesotriton'', also known as warty newts or Asian warty newts, is a genus of salamanders in the family Salamandridae. The genus is found in southwestern and southern China and in northern Vietnam. Most of the species are endemic to China, and the majority of them have been described recently, since 2008. The genus includes both pond and stream dwellers. Taxonomy and systematics The sister taxon of ''Paramesotriton'' is ''Laotriton''. The genus may be divided into two species groups (subgenera), ''Paramesotriton'' and ''Allomesotriton''. Description ''Paramesotriton'' have a dark brown dorsum with a prominent vertebral ridge, often also a pair of lateral ridges. The tail is high and laterally compressed. Skin texture varies from relatively smooth to very rough. ''Paramesotriton hongkongensis'' has toxic skin and ova, as has been shown for many other salamanders. Species ''Paramesotriton'' contains the following 14 species: * ''Paramesotriton aurantius'' Yuan, Wu, Zhou, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newt
A newt is a salamander in the subfamily Pleurodelinae. The terrestrial juvenile phase is called an eft. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats. Not all aquatic salamanders are considered newts, however. More than 100 known species of newts are found in North America, Europe, North Africa and Asia. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (eft), and adult. Adult newts have lizard-like bodies and return to the water every year to breed, otherwise living in humid, cover-rich land habitats. Newts are threatened by habitat loss, fragmentation and pollution. Several species are endangered, and at least one species, the Yunnan lake newt, has become extinct recently. Etymology The Old English name of the animal was , (of unknown origin), resulting in Middle English ; this word was transformed irregularly into , , or . The initial "n ...

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] |

Calotriton
''Calotriton'', or the European brook newts, is a genus of newts native to the Pyrenees and central Catalonia ( Catalan Pre-coastal Range). These amphibians were formerly placed within genus ''Euproctus'', but the genus was resurrected in 2005. Instead of ''Euproctus'', they seem more closely related to ''Triturus'', their sister taxon. Evolution ''Calotriton'' and ''Triturus'' are estimated to have split approximately 8 myr ago. This may have been associated with adaptation to fast-running, well-oxygenated mountain streams (instead of ponds in ''Triturus''), leading to some superficial similarity with ''Euproctus'' in convergent evolution Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time.

Laotriton
The Laos warty newt (''Laotriton laoensis'') is a species of salamander in the family Salamandridae. It is found only in the Saysomboun Special Zone and Phou Kout District in Xiangkhouang Province, Laos. Its natural habitats are subtropical or tropical dry shrubland and rivers. In 2014, it is classed as Endangered. Sometimes this newt is classified as ''Paramesotriton laoensis''. Since 1999, the population of this newt in the wild has been decimated by wildlife trading Wildlife trade refers to the of products that are derived from non-domesticated animals or plants usually extracted from their natural environment or raised under controlled conditions.

Salamandrininae
''Salamandrina'', the spectacled salamanders, is a genus of salamander, the only of subfamily Salamandrininae in the family Salamandridae which is still alive, as one of its own relatives is extinct. The IUCN Red List follows Mattoccia et al. (2005) and Canestrelli et al. (2006) in accepting two species, both only found in Italy: * Southern spectacled salamander (''Salamandrina terdigitata'') * Northern spectacled salamander (''Salamandrina perspicillata'') DNA testing is the most effective way to distinguish between S. ''terdigitata'' and S. ''perspicillata,'' however there is a some slight morphological differences between the two species. S. ''terdigitata'' is on average 1 cm shorter than S. ''Perspicillata'' as well as having more extensive red coloration on its Vental side. Fossils show that the genus formerly had a wider distribution during the Miocene and Pliocene The Pliocene ( ; also Pleiocene) is the epoch in the geologic time scale that extends from 5.333 milli ...

Taricha
The genus ''Taricha'' consists of four species of highly toxic newts in the family Salamandridae. Their common name is Pacific newts, sometimes also western newts or roughskin newts. The four species within this genus are the California newt, the rough-skinned newt, the red-bellied newt, and the sierra newt, all of which are found on the Pacific coastal region from southern Alaska to southern California, with one species possibly ranging into northern Baja California, Mexico. Species Genus ''Taricha'' contains the following species: Differentiating between species The rough-skinned newt and the California newt are very similar in appearance, and it can be extremely difficult to differentiate between the species. Both are light-brown to black on the upper body and orange to yellow on the underbelly. They have granulated skin, and they may grow to a length of eight inches. However, rough-skinned newts have small eyes with dark lower eyelids, while California newts have la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
