The earliest sharks date from more than 420 million years ago, before the time of the dinosaurs! The 400 species of modern sharks have evolved in various ways and scientists have classified them into the 8 major groups shown in this graphic. See how sharks fit into this family tree, from the most well-known sharks like the great white and tiger sharks, to the bizarre lesser-known sharks like the frilled shark, goblin shark and cookiecutter shark.”

Shark Week is huge, and that's kind of a problem →

Honestly, I’m not really a fan of Shark Week, at least not anymore. It’s all the same, and it’s not that great. I will not be blogging about it this season.
