This is a list of amphibians of Great Britain. There are seven amphibian species native to Great Britain , in addition, there are a number of naturalized species. The natives comprise three newts , two toads and two frogs .
Adult lungless salamanders have four limbs, with four toes on the fore limbs, and usually with five on the hind limbs. Within many species, mating and reproduction occur solely on land. Accordingly, many species also lack an aquatic larval stage, a phenomenon known as direct development in which the offspring hatch as fully-formed, miniature ...
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 never have more than four toes on their front legs and five on their rear legs, [ 3 ] but some species have fewer digits and others lack ...
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 ...
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.
Speleomantes, or European cave salamanders, are a genus of salamander in the family Plethodontidae, or lungless salamanders. It is one of two genera in the family to inhabit the Old World (the other being Karsenia ), with the remaining 250 or so species being found in North, Central and South America.
The origins and evolutionary relationships between the three main groups of amphibians (apodans, urodeles and anurans) is a matter of debate.A 2005 molecular phylogeny, based on rDNA analysis, suggested that the first divergence between these three groups took place soon after they had branched from the lobe-finned fish in the Devonian (around 360 million years ago), and before the breakup of ...
The northern two-lined salamander is a small salamander, with adults ranging from 65–120 mm in total length. [4] This salamander is yellow or yellowish-brown, with two black stripes running down the back which tends to break up after the base of the tail. The flanks are mottled grayish or brown. [5] The belly is pale yellowish, nearly ...
