Frogs Forever

Frogs are going extinct. So are toads, salamanders, newts, and the intriguingly unusual caecilians. In fact, the World Conservation Union (IUCN) estimates that at least one-third of known amphibian species are threatened with extinction - a higher percentage than either birds or mammals. While the major culprit is still habitat loss and degradation, many of the declines and extinctions previously referred to as "enigmatic" are now being attributed to the rapidly dispersing infectious disease chytridiomycosis ("chytrid"). This fungus is causing population and species extinctions at an alarming rate.

Explore our Frogs Forever pages to learn more about amphibians, what the Calgary Zoo is doing to help them, and how you too can jump in to help save them from extinction. Although 2008, Year of the Frog, is now over, efforts to save amphibians certainly do not end with the calendar year.

There are three groups of amphibians:

Frogs and toads (also called 'anurans')

There are more than 5000 species of anurans, making them the most diverse group of amphibians. Frogs and toads have short bodies, strong hind legs and no tail.

Salamanders, Newts and Mudpuppies

These amphibians have long bodies, tails, and short legs. The biggest amphibian in the world is the Chinese giant salamander, which can grow almost 2 m long. Alberta is home to 2 species of salamander.

Caecilians

These strange amphibians live mostly underground, and so aren't very well known.Caecilians are easy to tell apart from all other amphibians because they have no legs, making them look more like worms than frogs. Alberta is too cold to have any caecilian species, which prefer the warmth of the tropics.
