Description: Democrinus sp. or Monachocrinus sp. on the seabed. The photo is almost certainly not an isocrinid (or pentacrinitid according to my French colleagues). The stalk appears to be covered by either hydroids or zoanthids (which I have seen before) that can look a bit like the cirri of isocrinids. There is also a brittlestar at the base of the crinoid. Also, no isocrinids have only 5 unbranched rays at the size you record (It is about 150 mm in stalk length). In 550 m water depth, it is most likely Democrinus or Monachocrinus caribbeus.

Description: This appears to be a member of Charitometridae. Best guess is genus Glyptometra. There are several species known from the Indian Ocean and immediate vicinity at depths >1,000 m. However, the genus is likely oversplit, and the entire family needs revising. Item Type: Image Title: Crinoid Copyright: SERPENT Species: Glyptometra sp. Behaviour: Arms raised into water column to feed on plankton as the current passes through the fan shape created by the feather-like arms.
