essay on frogs, all around -


Frog is the common name for a species of

amphibian that also includes toads. A very common

question is "whats the difference between frogs and

toads?", the answer: none, except for the fact that toads

lack the powerful legs that frogs have. "Where can frogs

and toads be found?", one might ask. They live in all

parts of the world, except for Antarctica, but are mostly

found in tropical areas. Frogs are small animals with

smooth moist skin, and big eyes that can see in almost

any direction. Most species have webbed feet and

powerful legs making them good jumpers, and excellent

swimmers. A frogs tongue is attached to the front of it's

mouth instead of the rear, and most frogs are very vocal,

especially the male frogs.

As a frog grow, it goes through many changes.

Starting out as a tadpole, and morphing into a frog.

Most frogs lay their eggs in water. Others will lay their

eggs some where safe, then carry them to water where

they hatch into tadpoles. At this 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

of tadpole life can be divided into three stages. The first

stage, called "premetamorphosis," lasts about 50 days

(Patent 54). The second stage, in which the hind legs

grow, is called "prometamorphosis," and lasts about 21

days. When the legs are about as long as the body, the

third stage, which is called "metamorphic climax," and

takes place very rapidly, begins. During this last stage,

which lasts about a week, many great changes occur.

They lungs complete their development, and the gills

disappear. The skin gets thicker, nostrils form, and the

tail is completely...
