Brook salamanders are a genus, Eurycea, of salamanders native to North America.

Taxonomy

The genus Eurycea was first described by Constantine Samuel Rafinesque-Schmaltz in 1822, with a specimen of the spotted-tail salamander, Eurycea lucifuga , from Kentucky. The taxonomy of the genus is somewhat confusing, as many of the species within it are poorly studied and are found only in very restricted ranges, or deep within caverns. Several species have even been described several times by different researchers, and some are often considered to be morphologically different enough to warrant being placed into their own genera.

A recent taxonomic revision moved the Georgia blind salamander to this genus, which makes Haideotriton a synonym of Eurycea. [1]

Many sources also refer to several species of the genus as cave salamanders, due to their choice of habitat, or as blind salamanders, due to their reduced eyes, or the antiquated term for aquatic salamanders, Triton. Most species are from very isolated localities, so bear the name of the place the first specimen was found.

Diet

Eurycea eat a variety of small arthropods such as spiders, Armadillidiidae, and insects. [2] The food of larvae is at the same trophic level as the adults. E. cirrega, for example, eat isopods, chironomids, and copepods. [3]

Reproduction

Mating can occur from fall to spring. [3] [4] Males use their premaxillary teeth to scratch the female during reproduction, most likely to release various pheromones.

Ambystomatidae is a family of salamanders belonging to the order Caudata in the class Amphibia. It contains two genera, Ambystoma and Dicamptodon. Ambystoma contains 32 species and are distributed widely across North America, while Dicamptodon contains four species restricted to the Pacific Northwest. These salamanders are mostly terrestrial and eat invertebrates, although some species are known to eat smaller salamanders. They can be found throughout the US and some areas of Canada in damp forests or plains. This family contains some of the largest terrestrial salamanders in the world, the tiger salamander and the coastal giant salamander. Some species are toxic and can secrete poison from their bodies as protection against predators or infraspecific competition. Neoteny has been observed in several species in Ambystomatidae, and some of them like the axolotl live all of their lives under water in their larval stage.

The Texas blind salamander is a rare and endangered cave-dwelling troglobite amphibian native to San Marcos, Hays County, Texas, specifically the San Marcos Pool of the Edwards Aquifer. This species resembles the olm, another stygofaunal salamander from Europe. Unlike the olm, this amphibian's body is not as elongated, and also has less reduced digits on its limbs.

<span class="mw-page-title-main">Slender salamander</span> Genus of amphibians

<i>Scinax</i> Genus of amphibians

Scinax is a genus of frogs in the family Hylidae found in eastern and southern Mexico to Argentina and Uruguay, Trinidad and Tobago, and Saint Lucia. These are small to moderate-sized tree frogs, drably colored. Duellman and Wiens resurrected this genus in 1992. The name originates from the Greek word skinos, meaning quick or nimble.

<i>Trachycephalus</i> Genus of amphibians

Trachycephalus is a genus of frogs, commonly known as the casque-headed tree frogs, in the family Hylidae. They are found in Mexico, Central America, and South America. In a recent revision, the seven species of the genus Phrynohyas were included in this genus, and Phrynohyas is now considered a synonym of Trachycephalus. These frogs inhabit the canopies of tropical rainforests, where they breed in tree cavities, and seldom, if ever, descend to the ground.
