Sea Lilies and Feather Stars: Crinoidea - West Atlantic Stalked Crinoid (endoxocrinus Parrae): Species Accounts

Physical characteristics: West Atlantic stalked crinoids (CRY-noyds) are sea lilies with a stalk less than 3.3 feet (1 meter) long. Each arm has eight branches. Hairlike fibers on a curved stalk anchor the lilies to the material on which they live.

Geographic range: West Atlantic stalked crinoids live in the Atlantic Ocean near Florida, the Bahamas, and Cuba.

Habitat: West Atlantic stalked crinoids live in water 500 to 3,200 feet (150 to 975 meters) deep. They anchor themselves to hard surfaces.

West Atlantic stalked crinoids wave their arms rapidly up and down to prevent other animals and undesired particles from settling on the crown. They move from place to place by crawling over the bottom using their arms. (Illustration by Emily Damstra. Reproduced by permission.)
