Frogs are amphibians in the order Anura whose distribution of ranges from tropic to subarctic regions, but most species are found in tropical rainforests. Consisting of more than 5,000 species described, they are among the most diverse groups of vertebrates.
Known as exceptional jumpers, many of the anatomical characteristics of frogs, particularly their long, powerful legs, are adaptations to improve jumping performance. Typically laying their eggs in puddles, ponds or lakes, their larvae, called tadpoles, have gills and develop in water. Adult frogs follow a carnivorous diet, 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.
