Amphibians

Dart frogs Poison dart frog (also known as dart-poison frog , poison frog or formerly known as poison arrow frog ) is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America.[2] These species are diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity — a feature derived from their diet of ants, mites and termites[3][4]— while species which eat a much larger variety of prey have cryptic coloration with minimal to no amount of observed toxicity.[3][4] Many species of this family are threatened due to human infrastructure encroaching on their habitats. Subfamilies and genera Tree frogs A tree frog (or treefrog ) is any species of frog that spends a major portion of its lifespan in trees, known as an arboreal state.[1] Several lineages of frogs among the Neobatrachia suborder have given rise to treefrogs, although they are not closely related to each other. Millions of years of convergent evolution have resulted in very similar morphology even in species that are not very closely related.[2] Furthermore, tree frogs in seasonally arid environments have adapted an extra-epidermal layer of lipid and mucus as an evolutionary convergent response to accommodate the periodic dehydration stress. As the name implies, these frogs are typically found in trees or other high-growing vegetation. They do not normally descend to the ground, except to mate and spawn, though some build foam nests on leaves and rarely leave the trees at all as adults, and Eleutherodactylus has evolved direct development and therefore does not need water for a tadpole stage.
