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. With all the hype, it can be hard to separate the fact from the fiction. Are sharks friends or foe? Perhaps they are not either. Perhaps we should look at them as oft-misunderstood, ecologically-important predatory ocean fish. So what are sharks?
Sharks ARE ancient. Sharks are sometimes referred to as “living fossils”. Ancient sharks lived in the oceans long before animals colonized the land. 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.
