The San Diego Zoo does not have any goliath frogs in its collection.
Goliath frogs have been around for about 250 million years! They are one of only a few amphibians still alive that lived on Earth before the dinosaurs. But if the goliath frog has been around for millions of years, why are they endangered now? A lot has changed for the goliath frog over the years.
Major contributors to their decline are, unfortunately, humans. Many people enjoy eating frogs, and a goliath frog makes a big meal. Even though it is now against the law to hunt the goliath frog, poachers still do so to sell the delicious meat. Many goliath frogs are exported to the United States each year for frog-jumping contests!
The large frogs are also losing their forest habitat to farming, logging, and human settlements. These activities are adding extra soil to the frogs' breeding streams. Researchers find that the adult frogs weigh less than expected these days. There is also concern that all the large adults are being hunted, leaving only "teenagers." If this is so, soon there may not be any adult goliath frogs to reproduce.
