Cephalopods | Squids, Octopuses and Cuttlefish | The Wonderful World of Invertebrates
This informative video from the series "The Amazing World of Invertebrates" is dedicated to cephalopods, the most "alien" creatures on earth. Cephalopods are ancient, with their first relatives showing up in the geologic record 500 million years ago. That’s way before the dinosaurs and even before sharks! They are well known to people, attracting with their unusual appearance and meeting in the seas and oceans around the world. In addition, many of them are used by humans for food. However, the cephalopod world is huger and more fascinating than the limited taste of the restaurant world. The video tells about how cephalopods differ from each other, how many tentacles, hands and hearts these marine invertebrates have, why women need their ink, why octopuses, squids, cuttlefish and nautiluses are often called "smart aliens" and much more.
