Killer whales are the closest relative to the porpoise. They both feature large serrated teeth used for grabbing and holding onto prey for sustenance. They are also close relatives with the baleen whale that has a filter screen within it's mouth to filter sea water for small plant life like plankton.
No. Sharks are a type of fish. Porpoises are mammals.
TRUE
All dolphins and porpoises are mammals. They have hair (a tiny bit) and they are warm-blooded and they have live young which they feed milk.
Yes, porpoises are mammals.
Porpoises are mammals and so they are warm-blooded like you and I.
They are both mammals
Dolphins are mammals closely related to whales and sea cows. They are also related to hippos (but not as closely).
Orcas, like all whales and porpoises, are mammals along with their relatives, the dolphins.
Whales, porpoises and dolphins.
No, porpoises are not dolphins. While these two animals are both mammals they vary in size, physical characteristics, and behaviors.
Whales, dolphins and porpoises have a blowhole, (or nostrils), on top of their head so they can breathe in and out when they are on the surface of the water. Since they are the only mammals that spend their entire lives in the water, and much of it underneath the surface, they are the only mammals to have a blowhole on top of their head. Most mammals have their nostrils in the front of their face, similar to human beings.
Porpoises are mammals. Cheers, 99
