Answer 1

Answer:

Dolphins are mammals, not fish.

Unlike fish, who breathe through gills, dolphins breathe air using lungs. ... Whales and porpoises are also mammals. There are 75 species of dolphins, whales, and porpoises living in the ocean. They are the only mammals, other than manatees, that spend their entire lives in the water.
