BBC (London, UK) 31 July 04 Human croaks call frogs to dinner
An oceanarium is using Dr Doolittle's methods in order to find camouflaged frogs when it comes to meal time.
Staff discovered that the frogs responded to human croaks, allowing them to be located for their daily feed and regular health checks.
Oliver Buttling, from Bournemouth Oceanarium, said: "The croaking started as a bit of a joke among staff.
"But communicating with them makes our job a lot easier when it comes to feeding time."
The species Litoria caerulea, or White's Tree Frog, come from the Australian Rain Forest and New Guinea.
Nicknamed "the smiling frog" for their wide mouths, they can adapt to different environments and carefully camouflage themselves in leaves and bark to hide from predators.
Growing to a size of 10-12cm, they can live for up to 21 years, and are fed on a diet of live crickets, though they will eat almost anything, including mice.
