Narration:
Dolphins on the hunt strategize with one another.
They coordinate their movements with whistles and clicks.
But it's just as important what they don't say as what they do say.
Like any high school, being part of the in-crowd is incredibly important for dolphins.
They'll synchronize their swimming with their pals to show they're on the same wavelength.
They'll bully and they'll chase.
When alarmed, dolphins will close ranks to show solidarity.
And while some behavior may look playful, in certain contexts, it's downright rude.
Head shaking, jaw snapping and even bubble-blowing are ways a dolphin shows its annoyance...and anger.
