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 ...
Ribeiroia ondatrae, or the frog-mutating flatworm is a parasite in the genus Ribeiroia which is believed to be responsible for many of the recent increases in amphibian limb malformations, particularly missing, malformed, and additional hind legs. It was first reported from livers of Ondatra, hence its specific name. [1]
The Columbia spotted frog (Rana luteiventris) is a North American species of frog. It is a medium-sized frog reaching lengths of up to 3 + 1 ⁄ 2 inches (90 cm). Its color ranges from a dark, olive green to light brown with irregularly-shaped black spots on its back and legs (rendering its name).

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.
It is a fossorial frog that inhabits scrub-covered sandy areas in the succulent karoo biome. Development is direct [1] (i.e., there is no free-living larval stage [4]) and does require an aquatic habitat. [1] It is a locally abundant frog, but it can experience some habitat loss because of agricultural expansion in the south of its range. It is ...
AmphibiaWeb's goal is to provide a single page for every species of amphibian in the world so research scientists, citizen scientists and conservationists can collaborate. [1] It added its 7000th animal in 2012, a glass frog from Peru. [2] [3] As of 2022, it hosted more than 8,400 species located worldwide. [4] [5]
