because they are mammals and need to breath but they can underwater for a long time
fly
they can hear better out of the water
*tail
the dolphins eat their prey with their snobs
No mammals can breathe underwater. All mammals, including sea mammals, must breathe above the surface of the water. This is why marine mammals such as dolphins and whales frequently come to the surface.
Dolphins do have a strong tail with strong kick. That is showcased in many aquariums when they perform tail-walking above water or jumps.
Dolphins do not drink, but absorb water from eating their prey. Despite frequently using ecolocation, dolphins have very good eyesight both above and below water. Dolphins are considered mammals partly because they are born with hairs on their chins, which they lose shortly after birth.
Water mammal all rise to above the surface of the water in order to breathe air into their lungs: whales, dolphins, seals, etc.

Pink dolphins need water because they are dolphins.
Dolphins and Whales can stay under water for so long is because they have blowholes to come to the surface and get air. They can stay under water for quite a while before they need another breath at the surface:) Need more help... Just ask!!!!!!!!!!!!!!
Dolphins only sleep using half of their brain at a time, so they will still be above water and conscious of what they are doing when half of their brain is asleep, so they will still be breathing
Dolphins live in the sea water, but do not drink it. The ocean water is too salty for the dolphins system to handle.
