Relocation movement in a stalked crinoid (Echinodermata)

Although isolated observations of the isocrinid Endoxocrinus parrae (Gervais), indicate that it can crawl with its arms, in situ observations from submersibles during the last 15 years (Macurda and Meyer, 1974; 1976; Neumann et al., 1977; Messing, 1985) have not included extended time-series data for individual specimens essential for understanding the details of detachment and locomotion. The establishment by Research Submersibles, Ltd. of daily, shore-based submersible dives to 250 m off Discovery Bay, Jamaica, and, more recently, Georgetown, Grand Cayman Island, has allowed us to make repeated observations of individuals of the isocrinid, Cenocrinus asterius (Linnaeus), over extended periods and document their movement, reported herein.
