Frogs are amphibians in the order Anura (meaning "tail-less", from Greek an-, without + oura, tail), formerly called as Salientia (Latin saltare, to jump). The name frog derives from Old English frogga, (compare Old Norse frauki, German Frosch, older Dutch spelling kikvorsch), cognate with Sanskrit plava (frog), perhaps deriving from Proto-Indo-European praw = "to jump".
The basic characteristics are the long hind legs, a short body, webbed digits (fingers or toes), big eyes and the absence of a tail. Most frogs have a semi-aquatic lifestyle, but move easily on land by jumping or climbing. They typically lay their eggs in puddles, ponds or lakes, and their larvae, called tadpoles, have gills and develop in water. Adult frogs are carnivorous , mostly of arthropods, annelids and gastropods. Frogs are most noticeable by their call, which can be widely heard during the night or day, mainly in their mating season.
