Extreme longevity in proteinaceous deep-sea corals

Roark, Brendan; Guilderson, Thomas; Dunbar, Robert B; Fallon, Stewart; Mucciarone, David A

Description

Deep-sea corals are found on hard substrates on seamounts and continental margins worldwide at depths of 300 to 3,000 m. Deep-sea coral communities are hotspots of deep ocean biomass and biodiversity, providing critical habitat for fish and invertebrates. Newly applied radiocarbon age dates from the deep water proteinaceous corals Gerardia sp. and Leiopathes sp. show that radial growth rates are as low as 4 to 35 μm year -1 and that individual colony longevities are on the order of thousands of...[Show more]
