An early trip this morning, out of the Roche Harbor location. Up at 5:45 so I can get ready and be at the boat by 7:30 to prep it. I am pretty sure the whales are still asleep at this hour! ;-)

On edit: in the comments on this post, I answered the question, "How do whales sleep?"
It was chilly out on the water this morning, and my trip turned out to be more of a water-taxi trip than a whale watch tour... we picked them up on one island, found some interesting wildlife and nice scenery, while delivering them to another island.

How do whales sleep??
Good question - whales and dolphins are "conscious breathers," not involuntary, like humans. They decide when to surface and take a breath, so they don't sleep like we do. Like us, their brains have 2 hemispheres; unlike us, they go into a "resting state" where half their brain remains conscious, while the other half sleeps. We occasionally see this resting behavior: slow easy movements, and they tend to do this in small groups.
Your biology lesson for today. ;-)
