Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes , anteriorly-attached tongue , limbs folded underneath, and no tail (the tail of tailed frogs is an extension of the male cloaca).
Typically, true frogs are smooth and moist-skinned, with large, powerful legs and extensively webbed feet. The true frogs vary greatly in size, ranging from small—such as the wood frog (Lithobates sylvatica)—to large. Many of the true frogs are aquatic or live close to water. Most species lay their eggs in the water and go through a tadpole ...
A true toad is any member of the family Bufonidae, in the order Anura (frogs and toads). This is the only family of anurans in which all members are known as toads, although some may be called frogs (such as harlequin frogs). The bufonids now comprise more than 35 genera, Bufo being the best known.
The common coquí, widely known as the coquí (Eleutherodactylus coqui), is a species of frog native to Puerto Rico belonging to the family Eleutherodactylidae.The species is named for the loud call the males make at night, which serves two purposes; the "co" serves to repel other males and establish territory while the "quí" serves to attract females. [2]
All species of Eleutherodactylus are characterized by direct development, in which eggs hatch directly into small frogs, completely bypassing the tadpole stage. This adaptation (shared by few other frog genera, e.g. Myobatrachus) may be largely responsible for their ecological and evolutionary success. Most species are characterized by parental ...
It is the most common species of horned frog, in the grasslands of Argentina, Uruguay and Brazil. A voracious eater, it will attempt to swallow anything that moves close to its wide mouth, such as insects , rodents , passerine birds, snakes, lizards , and other frogs , even if this predator would suffocate in the process.

Pelophylax nigromaculatus (formerly Rana nigromaculata), is a species of true frog found in East Asia, first described in 1861. This widespread and common frog has many common names, including dark-spotted frog, black-spotted pond frog, and black-spotted frog. [1] [2]
Some 50 to 100 extant species are now placed in this genus by various authors; many other species formerly placed in Rana are now placed elsewhere. Frost [3] restricted Rana to the Old World true frogs and the Eurasian brown and pond frogs of the common frog R. temporaria group, [4] although other authors disagreed with this arrangement.
