This document discusses the adaptations of several aquatic animals including dolphins, sea turtles, orca whales, and sea lions. Dolphins have streamlined bodies, flippers, thick blubber, and use echolocation to hunt. Sea turtles have a shell for protection, strong flippers for swimming, and can stay submerged for long periods. Orca whales are highly social, hunt in pods, and have a varied diet including fish, seals, and even other whales. Sea lions have flippers they use to walk and swim, thick blubber, and inhabit cooler northern waters where they feed on fish and squid. All of these animals have developed characteristics that allow them to thrive in their aquatic environments
