The locomotion of the comatulid Florometra serratissima (Echinodermata: Crinoidea) and its adaptive significance

Abstract

Swimming is an escape response against potential predators. Crawling is the primary means of moving from place to place, and is induced by directional currents and by intraspecific contact. Spacing out within an aggregation may be accomplished by crawling following agonistic contact behaviour. -from Authors
