|Distribution of Leptodactylidae (in black)|
The Leptodactylidae (commonly known as the southern frogs) are a diverse family of frogs that probably diverged from other hyloids during the Cenozoic era, or possibly at the end of the Mesozoic. Of the roughly 50 genera, one, Eleutherodactylus, is the largest vertebrate genus, with over 700 species. In total, the approximately 1100 leptodactylid species are widely distributed throughout Mexico, the Caribbean, and Central and South America. The family is often considered paraphyletic and has no morphological synapomorphies. The family includes terrestrial, burrowing, aquatic, and arboreal members, inhabiting a wide range of different habitats.
Several of the genera within Leptodactylidae lay their eggs in foam nests. These can be in crevices, on the surface of water, or on forest floors. These foam nests are some of the most varied among frogs. When eggs hatch in nests on the forest floor, the tadpoles remain within the nest, without eating, until metamorphosis. In the genus Eleutherodactylus, the eggs undergo direct development and hatch directly into miniature frogs, with no free-living tadpole stage.
Leptodactylids are well represented in the fossil record, and one specimen from the genus Eleutherodactylus was wholly preserved in amber 37 million years ago.
