At what water depth does the blue whales live?

Answer 1

Most whales swim at the surface of the water since they're mammals and need to breathe air. Therefore, they don't go very deep into the ocean, since there really isn't any reason to. If they can get the majority of their food, krill, close to the surface, then there isn't a reason to go into deep water. Also, when a whale is sleeping, they are only half asleep, since they need to be awake enough to come up for air. Therefore, here they would also swim close to the surface to make it easier to surface for air. For exact numbers, the whale will go down to 1164 feet from the surface, or 0.2 miles, which isn't very big, considering the depth of the ocean. So a whale would live between the surface and 0.2 miles from the surface, normally.

Answer 2
