They have a think layer of blubber to store enegery and retain body heat. They once had external ears but have lost them, while the inner ear has changed to detect sounds underwater over long distances. This works with their echolocation which can determine the size shape and distance of an object underwater. They also have greasy tears in their eyes to protect them from the salt water.

Habitat

They live in warm waters in different areas during the different parts of their life. They inhabit the pelagic zone as well as harbors, gulfs, lagoons, bays, and estuaries. Dolphins can dive down to more than 1,000 feet

What do Zeh eat?

They eat mainly small fish but sometimes enjoy a good shrimp, crab, squid, or other small animals. Dolphins usually find find alone but have been known to hunt in larger groups when a larger group of fish is near. Dolphins have predators too though. Some sharks and orcas will eat dolphins. Dolphins are also inadvertantly trapped in fishermen's nets and dragged around to an ocean grave.
