Reddish Vale Country Park

Amphibians are creatures which spend part of their life in water and part of their life on dry land.

 

Frogs, toads and newts are all amphibians. They all start their lives as eggs. They hatch out as tadpoles which breath through gills. As they grow, they develop lungs and legs, and are able to leave the water and walk on land.

Amphibian is derived from the Ancient Greek term amphíbios which means both kinds of life, amphi meaning “both” and bio meaning life. The term was initially used for all kinds of combined natures. Eventually it was used to refer to animals that live both in the water and on land.

 

 

 

 

 

 

Dramatic declines in amphibian populations, including population crashes and mass localized extinctions, have been noted since the 1980s from locations all over the world.

 

These declines are perceived as one of the most critical threats to global biodiversity, and several causes are believed to be involved, including disease, habitat destruction and modification, exploitation, pollution, pesticide use, introduced species, and increased ultraviolet-B radiation (UV-B). However, many of the causes of amphibian declines are still poorly understood, and the topic is currently a subject of much ongoing research. Calculations based on extinction rates suggest that the current extinction rate of amphibians could be 211 times the background extinction rate and the estimate goes up to 25,039–45,474 times if endangered species are also included in the computation.
