Think of coral reefs and you imagine warm, shallow tropical seas, not the cold, dark waters of the deep ocean. Now the deep ocean's best-kept secrets are being revealed - ancient coral ecosystems hidden from view at great depths. is an information resource on the cold-water coral ecosystems of the deep ocean.

ckcultureplateAn exciting new section has been added to, courtesy of Dr Chris Kellogg at the US Geological Survey. Microbiology, the study of unicellular, microscopic organisms, is an important new area of research for cold-water corals. Just as humans have beneficial bacteria living on our skin and in our intestines, corals have symbiotic microbes in their mucus, tissues, and skeletons. It is possible that the microbes are helping to feed these corals, similar to the chemosynthetic bacterial symbionts that feed hydrothermal-vent worms. Unfortunately, there are also disease-causing microbes that can infect corals.

Identifying and characterising those bacteria will not only increase our understanding of microbial diversity, but could also uncover a new source of enzymes or pharmaceuticals.
