Like shallow-water corals, deep-sea corals may exist as individual coral polyps, as diversely-shaped colonies containing many polyps of the same species, and as reefs with many colonies made up of one or more species.Unlike shallow-water corals, however, deep-sea corals donât need sunlight.hen it comes to size, the range among deep-sea corals is tremendous. Scientists have discovered single polyps as small as a grain of rice, tree-like coral colonies that tower as tall as 10 m (35 ft), and massive coral reefs that stretch for 40 km (25 mi). But the ocean is a vast realm.
