Fact of the Day: Shark Bites

In order to mate for most shark species, male sharks have to bite parts of the female which do cause minor injury to the female shark. This is the reason why (due to natural selection) that female sharks have thicker skin than males.  


  1. Is that where humans get their biting fetishes from?

  2. So shark hickeys are a natural thing?

  3. I'm trying to imagine what evolutionary advantage comes from such behavior, but all I can do is laugh at the comments! Fun fact, Adam!
