This gallery highlights some of the unusual creatures at the heart of a recent Natural Resources Defense Council (NRDC) Op-Ed on Live Science's Expert Voices: Op-Ed & Insights.

Deep beneath the ocean off the U.S. Atlantic coast, forests of sea creatures thrive. New species are being discovered on the sea beds all the time, but a new report from the NRDC — "The Atlantic's Deep Sea Treasures," — warns that deep-sea trawling and energy exploration are putting those ecosystems at risk. Read more in the Expert Voices Op-Ed "Coral Thrive Off U.S. Atlantic Coast, But Threatened" and see a gallery of some of the exotic creatures below.

A creature from the past?
