2008 Year of the Frog

The world's leading conservationists have joined together to name 2008 "The Year of the Frog," in hopes of raising both awareness and funding needed to mitigate the amphibian extinction crisis. Another great place is Amphibian Ark, learn what you can do to keep them from becoming extinct. Please click on the links (highlighted in green) for more information. Now on to some frog Trivia

There are close to 4,000 known species of frogs, including
toads. They range in size from less than half an inch to
nearly a foot long and come in a rainbow of colors and
patterns.
***
Adult frogs are carnivorous and will eat just about anything
smaller than themselves, including insects, worms and even
other frogs.
***
The earliest known frog (Vieraella herbsti) appeared during
the late Jurassic period, about 190 million years ago. The
specimens that have been found in Arizona shows that the
skeletal shape and body plan of the frog has remained
almost unchanged.
***
The biggest frog is the appropriately named Goliath frog
(Conraua goliath) of Cameroon. They reach nearly a foot and
weigh as much as 7 lbs. The smallest frog is the Gold frog
(Psyllophryne Didactyla) of Brazil. They grow to only 3/8
inch.
***
Equally small is the Eleutherodactylus iberia discovered
only in 1996 in Monte Iberia, Cuba. (It doesn't even have
a common name yet.) Other small frogs are poison frogs.
They measure less than 1/2 inch.
***
Recently scientists have noticed a marked decline in the
numbers of frogs and other amphibians around the world.
Some species are believed to have become extinct within
the past fifty years. Causes for the decline include ozone
depletion, pollution, habitat loss, introduction of new
predators, disease and even a fungus.
