They had 10 equal sized tentacles studded with hooks to ensnare prey, without the two longer ones that characterise modern squid. They also had internal skeletons made of calcite, unlike their modern counterparts, and the most commonly fossilised part pictured here was at the rear of the animal. Rare examples with preserved internal parts indicate that they had ink sacs, hard beaks, large eyes and tailfins similar to modern cephalopods. They are often found in the stomachs of larger predators such as ichthyosaurs.
