Cricket Hits Copulation Record
Australian scaly cricket males can copulate 50 to

Scientists now believe infidelity is a genetic mechanism for creation
of healthy children: A report last week
in the Proceedings of the US National Academy of Sciences showed for
the first time that when a female guppy - a freshwater fish - is promiscuous,
rather than monogamous, she increases the quantity and quality of
her offspring. A study, in Nature, shows that hens mate with several
males, but actively choose which sperm they are fertilised by. Tim
Birkhead, professor of evolutionary biology at the University of Sheffield,
discovered that 'when females are mated by cocks they don't like they
just chuck the sperm out - they squirt it straight back out after
mating.'
