25 The Stalker
Known as the “lord of the seas,” Thalassomedon was a large sea monster with a very long neck. It also had a special means of catching fish: It carried stones in its stomach! These helped keep the largest part of its body and tail down in the dark water. Meanwhile, its long neck slowly rose up toward the fish. The fish didn’t have a chance to get away from Thalassomedon. They didn’t see the sea monster until it was too late
