It's a nice day in the cool waters of the reef. You're diving with a dive team, when suddenly...

A huge shape swims by. It's moving alarmingly fast, and it seems to have something large in its mouth.

You look up and see a giant ichthyosaur, resembling a Himalayasaurus, but even larger and more bulky. It's got a dolphin between its massive jaws, and quickly devours the small cetecean whole as it swims off to find more prey.
