The southern frogs form the Leptodactylidae, a name that comes from Greek meaning a bird or other animal having slender toes.They are a diverse family of frogs that most likely diverged from other hyloids during the Cretaceous. [1]
However, all archaeobatrachians have free vertebrae, whereas all other species of frogs have their ribs fused to their vertebrae. The Neobatrachia comprise the most modern species of frogs. Most of these frogs have morphological features which are more complex than those of the mesobatrachians and archaeobatrachians.
The tadpoles rely on the yolks of the eggs for nourishment. After six or seven weeks, they are ready for metamorphosis. The mother regurgitates the tiny frogs, which hop away from her mouth. [184] The female Darwin's frog (Rhinoderma darwinii) from Chile lays up to 40 eggs on the ground, where they are guarded by the male. When the tadpoles are ...
The Arthroleptidae / ˌ ɑːr θ r oʊ ˈ l ɛ p t ɪ d iː / are a family of frogs found in sub-Saharan Africa.This group includes African treefrogs in the genus Leptopelis along with the terrestrial breeding squeakers Arthroleptis, and several genera restricted to the Guinean forests of central and west Africa, such as the hairy frog (Trichobatrachus).
Linnaean taxonomy can mean either of two related concepts: The particular form of biological classification (taxonomy) set up by Carl Linnaeus, as set forth in his Systema Naturae (1735) and subsequent works. In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and the classes divided into lower ranks in a hierarchical order.
The hairy frog is also notable in possessing retractable "claws", which it may project through the skin, apparently by intentionally breaking the bones of the toe. [5] These are not true claws, as they are made of bone, not keratin. In addition, there is a small bony nodule nestled in the tissue just beyond the frog's fingertip.
Phylogenetically they stand between primitive frogs (fire-bellied toads, midwife toads) on the one side and higher frogs (the family of true toads, tree frogs, and the family of true frogs) on the other and are therefore – among other things by characteristics of bone construction – in the suborder Mesobatrachia.
The genus Leptodactylus's sister taxon is the genus Hydrolaetare. [5] The genus is composed of 4 species groups. [6] However, 3 species have not been assigned to a species group (L. hylodes, L. lauramiriamae, L. ochraceus). [5]
