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] |
California Newt (Taricha Torosa) (4415749606)
The California newt or orange-bellied newt (''Taricha torosa''), is a species of newt endemic to California, in the Western United States. Its adult length can range from . Its skin produces the potent toxin tetrodotoxin. Subspecies ''Taricha torosa'' was divided into two subspecies until 2007, when it was determined that the Sierra and coastal populations represent distinct evolutionary lineages. The former subspecies ''Taricha torosa sierrae'' was elevated to full species level and it is now known as ''Taricha sierrae'', the Sierra newt. ''Taricha torosa torosa'' has been retired and now all coastal populations are simply known as ''Taricha torosa'', the California newt. Range and habitat California newts reside in the coastal counties of California and in the southern Sierra Nevada (U.S.), Sierra Nevada and occupy a diverse array of habitats found near the small ponds and creeks where they breed, including woodlands and chaparral.

Taricha Granulosa
The rough-skinned newt or roughskin newt (''Taricha granulosa'') is a North American newt known for the strong toxin exuded from its skin. Appearance A stocky newt with rounded snout, it ranges from light brown to olive or brownish-black on top, with the underside, including the head, legs, and tail, a contrasting orange to yellow. The skin is granular, but males are smooth-skinned during breeding season. They measure 6 to 9 cm in snout-to-vent length, and 11 to 18 cm overall. They are similar to the California newt (''Taricha torosa'') but differ in having smaller eyes, yellow irises, V-shaped tooth patterns, and uniformly dark eyelids. Males can be distinguished from females during breeding season by large swollen vent lobes and cornified toe pads. Distribution and subspecies Habitats of rough-skinned newts are found throughout the Pacific Northwest. Their range extends south to Santa Cruz, California, and north to Alaska. They are uncommon east of the Cascade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taricha Rivularis
The red-bellied newt (''Taricha rivularis'') is a newt that is native to coastal woodlands in northern California and is terrestrial for most of its life. Description When full grown, the red-bellied newt measures between from its nose to its vent, and between from its nose to its tail. It has grainy skin, and is brownish-black on top with a tomato-red underbelly.Californiaherps.co''Taricha rivularis – Red-bellied Newt'' californiaherps.com The male red-bellied newt often has a dark, broad coloring across the vent, while females do not. Breeding males develop smooth skin and a flattened tail. The red-bellied newt can be distinguished from other coastal newts by its red belly and a lack of yellow in its eyes. Distribution and habitat The red-bellied newt is found in California along the coast from Bodega in Sonoma County, inland to Lower Lake, and north to Honeydew, Humboldt County.Stebbins, Robert C.; ''Amphibians and Reptiles of California''; University of California Pres ...

Taricha Sierrae
The Sierra newt (''Taricha sierrae'') is a newt found west of the Sierra Nevada, from Shasta county to Tulare County, in California, Western North America. Its adult length can range from . Its skin produces a potent toxin. Subspecies The Sierra newt was formerly regarded as a subspecies (''Taricha torosa sierrae'') of the California newt (''Taricha torosa''). In 2007 it was determined that the two represent "distinct evolutionary lineages". Range and habitat Sierra newts exist primarily in between the Cascades and Sierra Nevada, because they prefer less humid climates than the rough-skinned newts. The Sierra newt migrates between aquatic and terrestrial habitats seasonally. Outside the breeding season, the newts are land-dwelling, preferring rock crevices and logs, in habitats such as forests, woodlands, and shrub-lands. However, during breeding season, the newts will migrate to aquatic regions to mate and lay eggs. DFG Hatchery EIR-EIS - Appendix E: Biology of Decision ...

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 ...
