The Frog | amphibian

Frog, any of various tailless amphibians belonging to the order Anura. Used strictly, the term can be limited to any member of the family Ranidae (true frogs), but extra broadly the name frog is often used to distinguish the smooth-skinned, jumping anurans from squat, warty, hopping ones, which can be called toads.
In wellknown, frogs have sticking out eyes, no tail, and sturdy, webbed hind toes which are adapted for leaping and swimming. They additionally own clean, moist skins. Many are predominantly aquatic, but a few live on land, in burrows, or in bushes. A range depart from the typical form. Sedge frogs (Hyperolius), for example, are mountaineering African frogs with adhesive toe disks. The flying frogs (Rhacophorus) are tree-living, Old World rhacophorids; they could float 12 to 15 metres (forty to 50 feet) by way of expanded webbing among the palms and toes (see tree frog).
The snout-vent period of frogs degrees from 9.Eight mm (0.4 inch) within the Brazilian Psyllophryne didactyla to 30 cm (12 inches) in the West African Conraua goliath. The male anuran is typically smaller than the girl.

Although many frogs have toxic skin glands, these pollution do not usually offer protection from predatory mammals, birds, and snakes. Edible anurans rely on camouflage; some mixture with their backgrounds, while others exchange shades. Several species have bright hues on their underparts that flash when the frog moves, in all likelihood difficult enemies or serving as a warning of the frog’s toxicity. Most frogs eat insects, other small arthropods, or worms (see video), however some of them also eat other frogs, rodents, and reptiles.
The annual breeding of frogs usually takes region in sparkling water. In the sexual embody (amplexus), the male clasps the lady from at the back of and extrudes sperm over the eggs as they're ejected by means of the woman. The eggs, laid in numbers varying from a few hundred to several thousand (relying at the species), then flow off in clusters, strings, or sheets and might come to be connected to the stems of water plant life; the eggs of a few species sink. The tadpole hatches in some days to every week or greater and metamorphoses into a frog inside  months to 3 years. During metamorphosis the lungs increase, limbs seem, the tail is absorbed, and the mouth turns into normally froglike. In some tropical frogs, the eggs are deposited on land and the young hatch as froglets, rather than tadpoles.
