10 Horrifying Animal Facts You Really Don't Want To Know

2. Female Spiders Eat Males During And After Sex

If there were ever two words that shouldn't go together, it's "sexual cannibalism". But they do, and we're writing about it... so here goes. Female spiders exhibit this alarming behaviour during or after copulating with a male: they will slay him and then eat him as a possible form of "male sacrifice". We're not talking about the black widow here, either - those guys get a bad PR rap. While three species of black widows don't usually kill the male, the Australian redback spider gobbles up her partner after sex 65% of the time. Romantic.
