Invisible Oceans Founder's Collection: Invisible Oceans #63: Porpita III

Porpita from below, stinging tentacles arrayed radially, and pulsed downwards, towards camera, every now and again to sweep for micro planktonic organisms, which it conveys to its central mouth by flexing the tentacles across the tips of the manubrium lips.

Lizard Island, Australia (1988)
