Fish can obviously stay motioless in the water and shutdown to a degree.

Mammals still need to breathe on the surface every few mins so the half/half situation is mandatory.

There is also research into the "do Doplhins" dream question.

The "Do Whales have nightmares" question.

And "Can Bradley Johnson hit the target from 3 yards out" question.
