Description

Davidaster rubiginosa (Pourtalès, 1869) - golden crinoid in a patch reef. (photo taken by Mark Peter)

Crinoids (common names: sea lilies; feather stars) are sessile, benthic filter feeders. They are relatively common in the Paleozoic fossil record, but scarce in modern oceans. Most fossil crinoids have stems (stalks). Modern stalked crinoids are deep-water forms. Modern shallow-water crinoids are stalkless. The golden crinoid shown here lacks a stem and is a moderately cryptic species. Its body is hidden in cavities or crevices and feathery arms are extended while filter feeding.

Classification: Echinodermata, Crinoidea, Articulata, Comatulida, Comasteridae

Locality: Snapshot Reef, Fernandez Bay, western offshore San Salvador Island, eastern Bahamas
