SHARKS
In some form, sharks have been around for
about 400 million years.
Even before dinosaurs roamed the earth, sharks
hunted through the oceans! They're such good survivors that they've
had little need to evolve in the last 150 million years.
These ancient predators fascinate adults and
children alike.
Scientific Information: Sharks belong to
the class of fish, Chondrichthyes.
