Lemon Shark

Lemon sharks can grow a new set of teeth in eight days.
Sharks have several rows of teeth, two front rows for biting prey, and rows of teeth in the back that are used as backup. Sharks lack a hard jaw bone to keep their teeth in place, so they break and lose teeth all the time when they eat.

Shark teeth grow forward in a sort of ‘conveyor belt’ fashion, with lemon sharks having one of the highest replacement rates, replacing teeth every 7-8 days
