Here's a story that I read:
The grey nurse shark, pictured right, survives on a diet of fish, rays, shellfish, and, cannibalistically, other sharks. That last part is a habit they acquire at an early age — in the womb. Grey nurse sharks have two uteri and, regularly, give birth to two offspring at a time.
