3. Dolphin Communication • Dolphins communicate with some whistles to identify themselves. Unlike humans, dolphins miss vocal cords, but they use a system of squeaks, whistles, moans, thrills and clicks that are generated by sphincter muscles within the blow hole.While using echolocation, they send off frequencies by clicking sounds that bounce off objects which make the returning sound waves pick up the dolphin’s forehead and lower jaw annotate distance, size and the shape of an object.

6. The Delphinoidea Family Poem“Dolphins” Pushing through green waters Symbol of joy You leap from the depths To touch the sky Scattering spray Like handfuls of jewels Not caged by union rules Unfettered by sales targets No trains or planes to catch Your time is set by the flow Of the sea’s tides And the moon’s glow You give us images of ecstasy That we lock away Behind the doors of memory For quiet moments When released from our possessions We dream of a freedom like yours Back! Poem by Horace Dobbs
