Both Breathe oxygen and use pumped blood to distribute it through their bodies.
Whales, dolphins and porpoises are all mammals (there is an unrelated fish also called the Dolphin or Dolphinfish). These mammals evolved from extinct hoofed carnivores and gradually adapted to an exclusively marine life. Their similarity in form to fish is an example of convergent evolution; anatomical similarity to land mammals confirms their true origins.
they both live in the ocean and that is where the similarity ends. Sharks are fish and Dolphins are mammals.
No mammals are fish. Mammals and fish are distinct groups of animals with different characteristics. Mammals are warm-blooded vertebrates that have hair or fur, while fish are cold-blooded aquatic vertebrates that have scales and gills for breathing underwater.
Whales Are Mammals, Fish Are Not
Fish aren't mammals. But both fish and horses are vertebrates.
No! Whales are air-breathing mammals that give birth to live young. Whales produce milk for their young, which also designates them as mammals.
No if it's a shark your talking about. Mammals are defined as vertebral (Spined) and air breathing.
Whales are mammals, not fish, so they do not have gills for breathing underwater. Instead, they have lungs and need to come to the surface to breathe air.
There are no "fish mammals". Mammals are mammals and fish are fish. Mammals are warm-blooded creatures with fur or skin, breathing through lungs, and feeding their yong on mothers's mlk, while fish are cold-blooded creatures covered with scales, and which breathe using gills. There are, however, mammals which live underwater and, like all mammals, suckle their young on mothers' milk. These are dolphins, whales, narwhals, dugong, manatees and porpoises. Then there are the mammals which actually live on land, but spend much of their time at sea, and so have adaptations in their limbs which act as fins. These include walruses, seals and sea lions,
Mammals, birds, reptiles and adult amphibians breathe using lungs. Fish breathe using gills, while juvenile amphibians breathe using gills and spiracles.
No, fish are not mammals.
Fish are not mammals, they are fish.
