Short Wave: After A Whale Dies, What Happens?

The deep sea is a cold region of immense pressure and intense darkness.

Down there, most creatures subsist on dead and decaying material that falls from the surface, forming “marine snow” — dead plankton, dead animals shells, fecal matter, and other inorganic material.

But every so often, something larger reaches the sea floor. A dead whale.

Whale carcasses — known as “whale falls” — become an energy-rich habitat, drawing a wide variety of organisms from across the deep sea to feast. Whale falls become ecosystems unto themselves.

Diva Amon, a deep-sea biologist and Pew-Bertarelli Ocean Ambassador, as well as the Director and Founder of SpeSeas has studied them up close. Amon likens the arrival of a whale fall to a Thanksgiving buffet.

“Like your family coming from all over the country for these events, different species come from all over the deep sea to feast on this huge amount of carbon that has just arrived,” she says.
