Did you know that elephants have no scrotum??

And birds have different sex determining genes to mammals
in birds a ZW is a female and a ZZ is a male.

Be prepared for many other weird and wonderful bits of trivia as I study for Comparative Animal Physiology.

"The scrotum is the most prized possession of males yet it is so exposed and vulnerable"
ROFL!!! This is written in my actual CAP notes by the lecturer. *giggles*
