Scientists are trying to crack the secret code of a species of rare Borneo jungle frogs - who communicate with each other by waving.
The endangered reptiles - known commonly as the Lesser Rock Frog - greet each other by waving their hind legs and spreading out their toes like a 'high five.'
Experts had originally thought the waving was connected with breeding habits.
Now zoologists at Schonbrunn Zoo, Vienna, Austria - who bred more than a thousand of the beasts - reveal that they start waving almost as soon as they stop being tadpoles.
Zoo director Dagmar Schratter explained: "Experts believed this was a connection with reproduction.
"But now we know that juvenile animals wave before sexual maturity it is puzzling. We are studying this."
"We hope our visitors like them. With a bit of luck they might get a wave or two," she added.
