Sharks, Friend or Foe?

Duh-dum, duh-dum, duh-dum, …Shark Week! Well friends, it is that time of year again. Sharks take center stage this week on cable television.

Sharks have lived on earth for at least 400 million years! Most fossil evidence of early sharks exists as fossil teeth along with a few skin impressions. Ancestry of sharks dates back before the earliest known dinosaur. Although the dinosaurs are long gone, sharks still live on.
