Frog 2014

What is a Frog? There are around 3,900 species of tailless amphibians, or Anura, also called Salientia, including the frog and toad. Frogs are members of the zoological class called Amphibia. Amphibians are cold-blooded (or poikilothermic) vertebrate animals. They differ from reptiles in that they lack scales and generally return to water to breed. Amphibians together with reptiles make up a larger group called Herps. The study of reptiles and amphibians is called Herpetology. Herp comes from the Greek word herpeton, which basically means "creepy crawly things that move about on their bellies."

Generally speaking, though, when we think of frogs, we generally picture what are called "True Frogs".... members of the family Ranidae, containing more than 400 species. These frogs have the characteristics of: two bulging eyes strong, long, webbed hind feet that are adapted for leaping and swimming smooth or slimy skin (generally, frogs tend to like moister environments) Frogs tend to lay eggs in clusters.
