Sharks predate trees. Sharks have been cruising the oceans for over 400 million years—trees only appeared about 350 million years ago.
Sharks have roamed our seas for more than 400 million years, which means they evolved nearly 200 million years earlier than the first dinosaurs. During all this time, sharks have either shared or solely owned the position of the top predators in the marine food web. There are more than 400 different shark species, most of which can be found in coastal regions. They are present in every ocean of the world, with some species also inhabiting rivers.
