10 Animals That Are Total A**Holes
Female Jumping Spiders
A lot of female insects and arachnids eat their male counterparts during or after mating (sorry guys, that's the breaks), but female jumping spiders push that concept to the limit by forcing their suitors into a sick, deadly version of a "So You Think You Can Dance" audition.
Here's how it goes: the male jumping spider works really hard to perfect a complex courtship dance to woo his mate. He shows it to her, and if she's not impressed, she eats him. No sex, no second chance to show a different piece of choreography, just "Your dance sucked, so I'm gonna eat you now." Coooold!
