They are adapted to the Ocean
dolphins's bodies are made to serve a porpoise
they live where ever for a long time so they get use to it
Bottlenose dolphins have appendages similar to many mammals. They have adapted to swimming even though the bone structure is the same.
They love it when their trainers give them Donuts. Hope this helps. (: Gisela
Yes dolphins were four legged animals, they evolved into what they are now. At first they were wolf-like creatures but they adapted to water. It's the same way with whales.
Dolphins are adapted by their small layer of hair in the winter to keep them warm and in the summer they shred their hair. Their diet remains the same the whole time.
Dolphins have adapted to the marine environment like fish. However, anatomical (though some of their structures have become degraded or completely eliminated) characters resemble that of a mammal's. For example they have reproductive organs similar to that of mammals and they are viviparous
The modern relative to an ichthyosaur would be a dolphin. Both ichthyosaurs and dolphins are marine mammals that have streamlined bodies adapted for swimming in the ocean and fins for propulsion. However, ichthyosaurs are extinct, while dolphins are still alive today.
A Cetacean is an animal that belongs to the Order: Cetacea This includes Whales, Dolphins and Porpoises. Cetaceans are mammals fully adapted to Aquatic life and there are about 90 species.
Dolphin's can't swim without a tale because they don't have legs to kick and they have adapted to swimming like a normal fish.
Though one is a fish and one is a mammal they both have adapted to their immediate environment. Analogous traits.
Due to the fact that they both live in water they have adapted similar traits but a dolphin is warm blooded which is the difference.
