Dolphins are interesting species that sleep semi-consciously. The dolphin is unlike humans and cannot breathe subconsciously, but rather needs to be fully awake or conscious. To do this, dolphins will only sleep with half of their brain at one time. The other brain will remain awake to look out for predators and to continue breathing.

Dolphins also have interesting ways of communicating. They use a series of sounds such as squeaks, clicks and whistles. They also use a sonar process called echolocation, to learn about their environment and where prey is.
