From Monash University in Australia:
Promiscuous frogs spread eggs widely
Friday, 07 November 2008
A groundbreaking new study into the mating and nesting practices of a common Australian frog has found they partner up to eight males sequentially — the highest recorded of any vertebrate.
Dr Phillip Byrne from Monash University’s School of Biological Sciences has researched the Bibron’s toadlet (Pseudophryne bibronii) for six years and in this latest field trip, discovered a new behaviour undetected in a frog species until now.
“Our study revealed that females made the active decision to distribute their eggs between the nests of up to eight different males,” Dr Byrne said.
