Question

why do dolphins come to the surface of water to breath?​

Answer 1

Hey mate....

Here's your answer....

Dolphins are mammals that live underwater; instead of gills, they have lungs, which means that they must come to the surface for air. To breathe, a dolphin uses a hole in the top of its head called a blowhole; it first expels water to clear the hole, then takes a breath.
