Manatees are mammals. They must surface approximately every five minutes to breathe, but can hold their breath for as long as twenty minutes when resting. The manatee's nose is usually the only part of its body that comes out of the water when it breathes. If they are using a lot of energy, they may surface to breathe as often as every 30 seconds. Manatees rest from 2 to 12 hours a day either suspended near the water's surface or lying on the bottom, usually for several hours at a time.
