Sorry about a second “War Dolphin” thread I have started in as many days.

I was just curious, would these dolphins suffer from Jet Lag? They are mammals, so I assume they sleep (right?). Wouldn’t their internal clocks be just as screwed-up as a humans?

Dolphins don’t sleep like most other mammals. If they did, they would drown because they wouldn’t come up for air. Dolphins and other aquatic mammals can sleep one half of their brain at a time, while leaving the other half awake.

When they fly out to play the Raiders, they use that as an excuse, anyway.
