Ammonites used to live in the ocean (they are now extinct), because their entire bodies were designed for an underwater lifestyle. They could only breathe in the water, and they had no means of moving from place to place on land (ie, no legs, and they couldn't wriggle across the ground like a worm). They lived by floating in the seas, propelling themselves through the water with their tentacles, and eating small sea animals or plankton.

Various aquatic reptiles were predators of ammonites. Fossils of damaged ammonites have been found with teeth marks from Plesiosaurs.
