The list below largely follows Darrel Frost's Amphibian Species of the World (ASW), Version 5.5 (31 January 2011). Another classification, which largely follows Frost, but deviates from it in part is the one of AmphibiaWeb , which is run by the California Academy of Sciences and several of universities.
The marsh frog (Pelophylax ridibundus) is a species of amphibian native to Europe and parts of Asia. It is the largest type of frog in most of its range, growing to a snout-to-vent length of around 100 mm (4 in); tadpoles can reach up to 190 mm (7.5 in) in length, but this usually occurs in places with long winters where the tadpole has time to ...
The eggs of amphibians are typically laid in water and hatch into free-living larvae that complete their development in water and later transform into either aquatic or terrestrial adults. In many species of frog and in most lungless salamanders (Plethodontidae), direct development takes place, the larvae growing within the eggs and emerging as ...
Adult frogs may live in or near water, but few are fully aquatic. [159] Almost all frog species are carnivorous as adults, preying on invertebrates, including insects, crabs, spiders, mites, worms, snails, and slugs. A few of the larger ones may eat other frogs, small mammals and reptiles, and fish.
Pickerel frog: Adults are 2 to 3 inches (5.1 to 7.6 cm) long and colored green or brown with dark square spots. Rana pipiens: Northern leopard frog: Adults are 2 to 3.5 inches (5.1 to 8.9 cm) and colored green or brown with dark round spots. Rana septentrionalis: Mink frog: Adults are 2 to 3 inches (5.1 to 7.6 cm) long and colored a blotchy ...
Anura is an order of animals in the class Amphibia that includes frogs and toads. More than 5,000 species are described in the order. More than 5,000 species are described in the order. The living anurans are typically divided into three suborders: Archaeobatrachia , Mesobatrachia , and Neobatrachia .
A few species deposit eggs on land or bypass the tadpole stage. Adult frogs generally have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on plant matter. Frog skin has a rich microbiome which is important to their health. Frogs are extremely efficient at converting what they eat into body mass.
