New report documents amazing deep-sea coral, sponge resources

摘要

Deep-sea corals are among the slowest growing and oldest animals in the ocean, with some species living more than 4,000 years, and support ecosystems of incredible variety and diversity. Twenty percent of all known deep-sea coral species can been found off U.S. coastlines at least 50 meters (164 feet) below the ocean's surface. Deep-sea sponges can reach the size of a minivan, and may contain treatments for diseases such as pancreatic cancer. Many species create complex habitats that provide shelter, food, and nursery grounds, including for commercially important grouper, snapper, sea bass, rockfish, shrimp, and crab.
