Genetic evidence and some anatomical details (such as pedicellate teeth) support the idea that frogs, salamanders, and caecilians (collectively known as lissamphibians) are each other's closest relatives. Frogs and salamanders show many similarities to dissorophoids, a group of extinct amphibians in the order Temnospondyli. Caecilians are more ...
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]
Limnonectes is a genus of fork-tongued frogs of 91 known species, but new ones are still being described occasionally. [1] [2] They are collectively known as fanged frogs because they tend to have unusually large teeth, which are small or absent in other frogs.
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'.
African dwarf frog [1] is the common name for members of Hymenochirus, a genus of aquatic frog native to parts of Equatorial Africa. [ 1 ] [ 2 ] They are common in the pet trade and are often mistaken for the African clawed frog , a similar-looking frog in the same family.
The presence of teeth and other modern features of this prehistoric species can help researchers to better understand the evolutionary transition amphibians went through to get their unique ...
Lepidobatrachus laevis, widely known as Budgett's frog, is a species of frog in the family Ceratophryidae, discovered by John Samuel Budgett. [2] It is often kept as a pet . It has acquired a number of popular nicknames, including hippo frog , [ 3 ] Freddy Krueger frog , [ 3 ] and escuerzo de agua .
