Lizard is the common name used for all squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, [1] ranging across all continents except Antarctica, as well as most oceanic island chains.
Most reptiles are viviparous, although oviparous reptiles do exist. Oviparous reptiles often display very little or no maternal behavior after the eggs have hatched, while viviparous reptiles typically exhibit more extensive maternal care. [1] Nile crocodiles however, are the exception to this.
Reptiles tend to avoid confrontation through camouflage. Two major groups of reptile predators are birds and other reptiles, both of which have well-developed color vision. Thus the skins of many reptiles have cryptic coloration of plain or mottled gray, green, and brown to allow them to blend into the background of their natural environment. [135]
The hairy frog (Trichobatrachus robustus) also known as the horror frog or Wolverine frog, is a Central African species of frog in the family Arthroleptidae.It is typically considered monotypic within the genus Trichobatrachus, [2] but based on its genetics, it should be included in Astylosternus instead.

Calling all budding herpetologists! These are the best types of reptiles you can keep as a pet
Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards).

They have scaly skin and live a fairly nocturnal existence. They are relatively small-sized crocodilians with an average maximum weight of 6 to 40 kg (13 to 88 lb) depending on species, with the exception of the black caiman (Melanosuchus niger), which can grow more than 4 m (13 ft) in length and weigh in excess of 450 kg (1,000 Ib). The black ...
The cloud of small bristles can get into the mucous membrane of small mammals and cause edema, which can be fatal. The bristles cause both mechanical and chemical harm to the skin and membranes. Humans' reaction and the degree of irritation to a defensive urticating hair barrage can vary tremendously, based on the species in question.
