Dr. Wallich, the pioneer of deep-sea research, eighteen years ago recognized the deep homothermal sea “As the great highway for animal migration, extending pole to pole” Below 500 fathoms it is everywhere dark and cold, and there are no ridges . . . → Read More: Biogeography of the Deep Sea
Japanese researchers recently set a record with the deepest in-situ observation of a criniod. In the words of the authors, Previous records of stalked crinoids from hadal depths (exceeding 6000 m) are extremely rare, and no in-situ information has been available. We show here that stalked crinoids live densely on rocky substrates at depths . . . → Read More: The Deepest Crinoids
