Yes. Most dolphins can only hold their breath for 9 minutes, so of coarse they do! How dolphins do this is because they have 2 brains- the right one controls the left side of the body, and the left one controls the right side of the body. Both brains are connected, and take turns letting the dolphin automatically float up to the surface, and let the blowhole breath out, then in. All when the dolphin is sleeping.
