Sea slug's 'disposable penis' surprises

A sea slug that is able to detach, re-grow and then re-use its penis has surprised scientists.

Japanese researchers observed the bizarre mating behaviour in a species called Chromodoris reticulata, which is found in the Pacific Ocean.

They believe this is the first creature known that can repeatedly copulate with what they describe as a "disposable penis".

The study is published in the Royal Society's journal Biology Letters.

I'm more surprised that the BBC used a naughty word like "penis". That would never have happened if Mary Whitehouse were till alive.
