I've never heard anything so bizarre in my life.  This one's out of a New Zealand aquarium. (Thanks to Heather over at the Beehive for posting this.)

Visitors watched in shock as a shark swam over to another and bit it in the belly.  Then... four babies swam out!  I guess the first shark had to bite the second one in a specific spot, or else the mom and babies would've likely died.  Aquarium workers had no idea that the shark was even pregnant, and were able to save them all.

I will never complain about my c-section scar ever again.

Here's Heather's original post.
