In early spring the females nest on land, along the banks of small ponds. After the 4–6 week embryonic period, the larvae hatch and make their way to the adjacent pond. Four-toed salamanders undergo a relatively short aquatic larval period, when compared to other species of the same family, ranging between 3 and 6 weeks. [3] [4] [6]
Northern and northwestern Arkansas Four-toed salamander: Hemidactylium scutatum (Temminck, 1838: Imperiled [46] Western Arkansas in central Ouachita Mountains, distinct population in Cleburne County: Western slimy salamander: Plethodon albagula Grobman, 1944: Apparently secure [47] Forms a species complex with P. kiamichi and P. kisatchie
Many species within this group (including the nominal species) are commonly known as "slimy salamanders", characterized by a large size, robust build and black-and-white coloration. Not all members of the Plethodon glutinosus group are labelled as slimy salamanders, and species delimitation among slimy salamanders and their close relatives is a ...
The Caddo Mountain salamander (Plethodon caddoensis) is a species of salamander in the family Plethodontidae endemic to Arkansas in the south-central United States, and only known from the Caddo Mountains, a part of the Ouachita Mountains. [1] [2] [3]
The subspecies is strictly native to the mountain streams of the Ozark Plateau in southern Missouri and northern Arkansas. [4] Its nicknames include lasagna lizard and snot otter. [5] This large salamander grows to a total length (including tail) of 29–57 cm (11–22 in) over a lifespan of 30 years. [6]
The Rich Mountain salamander (Plethodon ouachitae) is a species of salamander in the family Plethodontidae. It is endemic to the Ouachita Mountains in western Arkansas and eastern Oklahoma. Its natural habitat is temperate forests. It is threatened by habitat loss.
[4] It was described in 1968, but was later synonymized with the grotto salamander (E. spelaea), but a 2017 study found substantial genetic differences between the clades classified in E. spelaea and once again split them into distinct species. It is thought to have diverged from the northern grotto salamander (E. nerea) during the Late Miocene ...
Biofluorescence in a three-toed amphiuma. The three-toed amphiuma looks rather eel-like, with an elongate, dark gray-black, or brown colored body, and tiny vestigial legs. A large salamander, one record sized individual was recorded at 41.25 inches (104.8 cm), but 18–30 inches (46–76 cm) is the typical size of an average adult. [3]
