Editor’s Note: While Peter Baker’s commentary notes that New England fishery managers “have not yet put forward a plan for protection” of New England’s deep-sea corals, the New England Fishery Management Council (NEFMC) has in fact been working since 2012 to extend protections to the region’s coral habitats. The Council’s effort, the Omnibus Deep-Sea Coral Amendment, is still in development, but contains protections similar to the much-lauded coral protections enacted by the Mid-Atlantic Fishery Management Council through their own Deep Sea Corals Amendment.
December 8, 2015 — Less than 100 miles offshore from the heavily populated Eastern Seaboard lie submerged seascapes that look more like visions from another world than the cities and landmarks for which they are named.
Baltimore Canyon, Norfolk Canyon, Hudson Canyon, and others were carved by ancient rivers back when seas were shallow and the coastline was radically different. Now, these undersea canyons gouge into the edge of the continental shelf, plunging thousands of feet seaward to the abyss.
Scientists, exploring these places with robotic submersibles, have upended our assumptions about the deep sea. Far from a barren seafloor, these canyons teem with life—from familiar fish, squid, and crabs to some animals so bizarre that they could easily pass for creatures in a sci-fi flick. Some of the stranger sightings here include gangly crustaceans called sea spiders; the long-nosed chimera, or ghost shark; and the comical “Dumbo” octopus, which propels itself with earlike protrusions.
Most amazing, perhaps, are the living structures known as deep-sea corals that many of these animals depend upon for habitat. Unlike the familiar corals of the warm, shallow waters, these corals are adapted to the cold, dark depths where they slowly grow. Colorful bubblegum corals form bulbous ends in bright pinks, while fan corals grow in veined sheets of maroon and brown. Many deep-sea corals are centuries old, and some are among the Earth’s oldest known living animals.
