Abstract

The symbiotic pearlfish Carapus bermudensis (Jones) demonstrates the ability, as an adult, to relocate the host sea cucumber Actinopyga agassizi in the laboratory. Host location behavior is effected unimodally with chemically mediated information of host orgin. Positive orientation of pearlfish to host “odor” does not involve chemically-elicited rheotaxis.
