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]
In response to the conditions of the environment, some mammals, such as bat delay the implantation due to the cold temperature in winter. [37] Another factor is due to the shortage of food stocks during winter as the insects are being driven away and as the result, bat hibernate in pregnant condition. [38]
This list is derived largely from the Herps of Arkansas website. [1] Conservation status is derived from NatureServe and represents the species' status within the state rather than their worldwide status. In Arkansas, there are 25 species of frog and toad, and 32 species of newts and salamanders.
[15] [16] The common mudpuppy never leaves its aquatic environment and therefore does not undergo morphogenesis; however, many salamanders do and develop differentiated teeth. [17] Aquatic salamander teeth are used to hinder escape of the prey from the salamander; they do not have a crushing function. [17] This aids the salamander when feeding.
The ringed salamander (Ambystoma annulatum) is a species of mole salamander native to hardwood and mixed hardwood-pine forested areas in and around the Ozark Plateau and Ouachita Mountains of Arkansas, Oklahoma, and Missouri. [2] This species of salamander has slander body, small head, and long tail.
The Ouachita dusky salamander grows to about 17.8 centimetres (7.0 in) in length including a finned tail. The upper side is greenish-brown or grey of a fairly uniform colour and the juveniles have a row of pale spots along each side. There are fourteen costal rib grooves on either side. [2] [3]
It is now considered a member of the genus Eurycea, but was originally described as Typhlotriton braggi. [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.
Little is known of its breeding habits, but they are likely to be similar to the Rich Mountain salamander. The eggs are laid in underground chambers and brooded by the female, no aqueous larval stage exists and direct development takes place into juvenile salamanders. Females may breed in the fall or winter in alternate years.
