The Mantellidae are an amphibian family of the order Anura (frogs and toads), and are endemic to the Indian Ocean islands of Madagascar and Mayotte. [1] [2] At first glance, the diminutive, brightly-coloured mantellas appear visually similar to (and indeed fill similar ecological niches as) the Latin American poison dart frogs, such as Dendrobates, Oophaga and Phyllobates, among others.
The temnospondyl Eryops had sturdy limbs to support its body on land Red-eyed tree frog (Agalychnis callidryas) with limbs and feet specialised for climbing Japanese giant salamander (Andrias japonicus), a primitive salamander The bright colours of the common reed frog (Hyperolius viridiflavus) are typical of a toxic species Wallace's flying frog (Rhacophorus nigropalmatus) can parachute to ...
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.
North America has many species of the family Hylidae, including the gray tree frog (Hyla versicolor) and the American green tree frog (H. cinerea). The spring peeper ( Pseudacris crucifer ) is also widespread in the eastern United States and is commonly heard on spring and summer evenings.
Diets vary widely, with examples including Paracassina, which specializes in snails, [3] and Afrixalus fornasini, the only terrestrial frog known to prey on eggs of other species of anurans. Breeding in this family begins at the start of the rainy season, when hyperoliids congregate at breeding sites.

The majority of species still live in the oceans, from the seashores to the abyssal zone, but some form a significant part of the freshwater fauna and the terrestrial ecosystems. The mollusc phylum is divided into nine or ten taxonomic classes , two of which are extinct .
Amphibian Species of the World 6.2: An Online Reference (ASW) is a herpetology database. It lists the names of frogs, salamanders and other amphibians , which scientists first described each species and what year, and the animal's known range.
