Bonnerichthys gladius.

The abundance of the seas can feed giants as blue whales, the largest animal ever. An animal prey are among the smallest in the world. Enter in their mouths a lot of water full of plankton is trapped in the baleen to filter the water.

But this way of eating is not unique in today's whales. There were huge fish that fed the same way. For example Bonnerichthys gladius. A fish of about 8 feet long that lived in the oceans for over 100 m illion years in what is part of the Cretaceous and Jurassic

The gladius Bonnerichthys had a disproportionate head, big eyes, toothless mouth, butextremely elongated jaws. He is credited with the first animal that was fed by filtration.

By the way, do not remember the basking shark??
