Striped dolphin body language

A striped dolphin opens its mouth, possibly a warning sign to other group members.

While dolphins may not have a complex facial mimics (they can do little else than opening and closing their mouth), they certainly can express emotions and convey information about their "mood" by the way they move, occasionally also producing bubble streams via their blowhole.

And of course they possess a rich vocal repertory of pulsed and modulated sounds.
