Another weird and wonderful tale from the animal world, described by Ed Yong on 'Not exactly rocket science'.
'For a small Amazonian frog called Rhinella proboscidea, death
is no impediment to sex. The males form huge mating balls in which
dozens of individuals compete to fertilise a female. These competitions
are so intense, and the combined males so heavy, that the poor female
sometimes drowns in the struggle.
But for the males, that’s not a deal-breaker. Thiago Izzo from
Brazil’s National Institute of Amazonian Research has found that the
males can force the eggs from the bodies of the deceased female, and
fertilise them. It’s a unique strategy and one that effectively involves
sexual reproduction with a dead partner. Izzo calls “functional
necrophilia”.'
