How Many Species?

For a long time,

because deepsea corals were so inaccessible, no one had any idea how many species existed. Now, by studying specimens collected on research expeditions, They study the corals shape and form (morphology) to identify species that are known to be found in other locations and species that are new to science. Because so many species of deepsea corals look alike, marine researchers may do DNA testing to confirm the results.
