Whales are believed to sleep for very short time spans. They seem to
shut down half of their brain at a time, because if they shut their
entire brain down, they would stop breathing. Humans don't need to
be conscious to breathe. We can sleep and still breathe. But whales
must remind themselves constantly to breathe. With right whales, we
have seen that the whales will seem to fall asleep and start sinking
under the surface. However, they wake up in a few minutes and rise
to the surface to breathe.
Don't forget to use the WhaleNet pages for more detailed information.
Try the how to find section at

archives as well. Thak you and happy holidays!
