What is a Frog?

There are around 3,900 species of tailless amphibians, or Anura, also
called Salientia, including the frog and toad.
Amphibians

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. They are one of three types of Amphibians. Anura, also called Salientia, (frogs and toads), caudate (salamanders and newts) and caecilians (worm-like amphibians).

Herps and Herpetology

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."
A herptile is an individual herp. A person who keeps and breeds herps is called a herpetoculturist and the hobby is called herpetoculture.
Albino Frogs

Albino frogs are a fairly common occurance with frogs... It seems to happen with many different species of frogs and should not be taken to mean that your frog is sick. Albinism is a condition caused by a recessive gene which causes a person or animal to be born lacking normal pigmentation. What you end up with is usually a pinkish or whitish or GHOSTLY looking frog, with really weird-looking red eyes. The eyes appear red because the blood vessels of the retina show through the iris, giving it a pink or reddish color.
The eyes of albino animals (and people!) tend to be highly sensitive to light.
For the most part though, folks with albino pets dont have anything to worry about.
These funky colorings can look either really cool or really freaky, depending on the species. It can also make it pretty tricky to identify the species of frog.
