Democrinus sp. or Monachocrinus sp.
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.
