Answer 1

Dolphins can be awake and asleep at the same time because:

1. one side of the brain can sleep while the other side maintains swimming and breathing behaviors.

Step-by-step explanation:

As incredible as it may sound, dolphins are indeed able to sleep with only half of their brain. The other half remains awake, but less alert then when they are awake. One of their eyes remains open, and their breathing and swimming behaviors are maintained. This is particularly helpful when predators are around or when obstacles are in their way. It also keeps them from drowning.
