Does anybody KNOW why aquatic mammals' testicles are inside the body cavity,
while most mammals' body temperature is too high for sperm survival?
Is it that aquatic mammals have lower body temperatures or is it perhaps
that their sperm can withstand higher temperatures? 

Please e-mail me back directly!
many thanks.
