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).
Male Rana temporaria calling in a garden pond in Jambes, Belgium. The common frog or grass frog (Rana temporaria), also known as the European common frog, European common brown frog, European grass frog, European Holarctic true frog, European pond frog or European brown frog, is a semi-aquatic amphibian of the family Ranidae, found throughout much of Europe as far north as Scandinavia and as ...
Sources say frogs use low frequency sound of rain as a cue to emerge from aestivation. [12] While olfactory cues are considered a secondary emergence stimulus, there is evidence in other anurans that the smell of emergent plant growth can also guide frogs to breeding sites, specifically pond weed species.
Rana (derived from Latin rana, meaning 'frog') is a genus of frogs commonly known as the Holarctic true frogs, pond frogs or brown frogs. Members of this genus are found through much of Eurasia and western North America .
The yellow-bellied toad lays eggs in ponds of a particular temperature and duration. When given the choice between a warm pond, or a cooler one, the frog will lay its eggs in the warmer pool because of heat being conducive for healthy egg growth and development.

The spring peeper (Pseudacris crucifer) [3] is a small chorus frog widespread throughout the eastern United States and Canada. [4] It prefers permanent ponds due to its advantage in avoiding predation; however, it is very adaptable with respect to the habitat it can live in.
Most species (e.g. Blyth's river frog L. blythii or the fanged river frog L. macrodon) develop normally, with free-swimming tadpoles that eat food. [5] The tadpoles of the corrugated frog (L. laticeps) are free-swimming but endotrophic, meaning they do not eat but live on stored yolk until metamorphosis into frogs. [5]
