Australian Green Tree Frogイエアメガエル

Litoria caeruleaLC— Least Concern

The Australian green tree frog is a large, robust tree frog native to northern and eastern Australia and the lowlands of southern New Guinea. Nocturnal and highly adaptable, it hunts insects, spiders, smaller frogs, and even small mammals, and has become well known for turning up in unexpected human spaces such as toilet cisterns in search of moisture. Its scientific name, meaning "blue," is a historical misnomer stemming from early specimens that discolored in preservative, and the species remains a popular, long-lived amphibian in captivity, with some individuals living over 20 years.

Did You Know?

  • The male's mating call is remarkably loud and can sometimes be heard from several hundred meters away. Source
  • Its adaptability to human environments is well documented—individuals are sometimes found seeking moisture inside toilet cisterns in houses. Source
  • The species epithet caerulea means "blue," a misleading name that arose because early preserved specimens lost their yellow pigment layer to preservative damage, making them appear blue. Source

FAQ

Why is the Australian green tree frog scientifically named for the color blue?
The name is a historical accident: early preserved specimens lost their yellow pigment layer to chemical damage from preservatives, making them appear blue rather than their natural green color. Source
How long do Australian green tree frogs live?
In captivity they average around 16 years, and some well-cared-for individuals have been documented living more than 20 years, with one record reaching 23 years. Source
Why do these frogs sometimes turn up in houses?
They are highly adaptable to human environments and will seek out moisture wherever they can find it, occasionally being discovered inside toilet cisterns or other damp indoor spaces. Source
