Male octopus is a sucker for big girls who kill him after sex. (Sydney Morning Herald)

"The male blanket octopus faces a significant gender imbalance - he is just two centimetres long, while the female of the species can measure up to two metres.

And as if being 100 times smaller than his mate wasn't bad enough, he dies right after having sex with her."

Isn't nature wonderful?
