Frogs :: essays research papers

FrogsFrog is the common name for a species of amphibian that alike includestoads. A truly common question is whats the difference between frogs and toads?, the suffice none, eject for the fact that toads lack the effective legs thatfrogs have. Where tail end frogs and toads be prime?, one might ask. They live on inall parts of the world, except for Antarctica, but are mostly found in tropicalareas. Frogs are small animals with smooth moist pare down, and big eyes that fuck hold in almost any direction. Most species have webbed feet and powerful legsmaking them good jumpers, and excellent swimmers. A frogs tongue is attached tothe straw man of its mouth instead of the rear, and most frogs are very vocal, particularly the male frogs.As a frog grow, it goes through many changes. get-go out as a tadpole,and morphing into a frog. Most frogs lay their testicle in water. Others will laytheir eggs some where safe, then bring them to water where they hatch intotadpoles. At thi s stage they have gills, no legs, and a tail. As they mature,their gills and tail disappear, and they develop lungs and legs. This period oftadpole life can be divided into three stages. The first stage, called premetamorphosis, lasts about(predicate) 50 long time (Patent 54). The second stage, in whichthe hind legs grow, is called prometamorphosis, and lasts about 21 days. Whenthe legs are about as long as the body, the third stage, which is called metamorphic climax, and takes place very rapidly, begins. During this laststage, which lasts about a week, many gr release changes occur. They lungs completetheir development, and the gills disappear. The skin gets thicker, nostrilsform, and the tail is completely resorbed.Most frogs prefer moist regions, and many kinds live in the water.Because frogs absorb oxygen in water through their skin, they can stayunderwater for long periods of time. A frogs body temperature depends on itssurroundings, and during cold weather, frogs dig burrow s in mud and hibernate.During hibernation, the frog needs petite oxygen and no more food than isalready in its tissues. During intense heat, a frog might estivate, or in opposite words, lie in a state of torpor during the heat, after entombment themselvesin sand and clay.Frogs are carnivores. They eat just about anything smaller than thenthat moves. A frog thinks like this If its smaller than itself and moves,eat it. If its the same size, mate, or attempt to mate (this gets some frogs
