The Chinese calendar says 2008 is the year of the Rat, but according to the Association of Zoos and Aquariums (AZA), 2008 should be the Year of the Frog. The reason is that frogs are disappearing from our planet at an alarming rate and, in a few years, they may all be extinct.
In August 2007, more than 230 delegates representing zoos and aquariums from 35 countries gathered in Hungary to sign a petition, calling on governments to help preserve amphibian life. This marks the first time that zoos and aquariums have initiated a global call to action on behalf of an endangered class of animals. Their concern is that one-third to one-half of all species of frogs are in danger of becoming extinct in the near future — which would be the largest mass extinction since the disappearance of the dinosaurs.
About 4,000 species of amphibians exist worldwide and most of them are frogs and toads. The term amphibian comes from the Greek amphibios and means double life, referring to the fact that they begin life in the water as tadpoles and gradually transform themselves into land dwelling creatures with legs. Frogs are "cold-blooded" and rely on the environment to regulate their body temperature. The skin of a frog is moistened by the secretion of numerous mucous glands and plays a vital part in the frog's water balance, respiration and protection. But since the skin is highly permeable to water, it also makes them highly susceptible to environmental changes.
