Some species are carnivorous at the tadpole stage, eating insects, smaller tadpoles, and fish. The Cuban tree frog (Osteopilus septentrionalis) is one of a number of species in which the tadpoles can be cannibalistic. Tadpoles that develop legs early may be eaten by the others, so late developers may have better long-term survival prospects. [152]
Paedophryne amauensis, also known as the New Guinea Amau frog, is a species of microhylid frog endemic to eastern Papua New Guinea. [ 2 ] [ 4 ] At 7.7 mm (0.30 in) in snout-to-vent length , it was once considered the world's smallest known vertebrate .
This makes the species even more unique, as PLOS One said, because other frogs that skip the egg step typically give birth to froglets, or baby frogs, but these frogs still give birth to tadpoles.
The African clawed frog (Xenopus laevis), also known as simply xenopus, African clawed toad, African claw-toed frog or the platanna) is a species of African aquatic frog of the family Pipidae. Its name is derived from the short black claws on its feet. The word Xenopus means 'strange foot' and laevis means 'smooth'.
The average life expectancy of these frogs is five years, but they have been known to live longer than 20 years, [4] and they can grow to 1" to 1.5" long. African dwarf frogs can be mistaken for and are often sold as young African clawed frogs, of the genus Xenopus, which are larger and more aggressive than the dwarf. [citation needed]
Xenopus (/ ˈ z ɛ n ə p ə s / [1] [2]) (Gk., ξενος, xenos = strange, πους, pous = foot, commonly known as the clawed frog) is a genus of highly aquatic frogs native to sub-Saharan Africa. Twenty species are currently described within it.
