Abstract

This study was designed to determine the sensory basis of host location by the pearlfish, Carapus bermudensis (Jones). Forty-eight hour aquaria observations and examination of stomach contents revealed that pearlfish emerge, probably nightly, shortly after dark and feed on small crustaceans. Experiments in a two-way choice apparatus demonstrate that pearlfish locate the host holothurian, Actinopyga agassizi (Selenka), by olfaction. Vision and rheotaxis are not used as alternative methods of' host location or in conjunction with olfaction. These findings are analyzed in terms of the present knowledge of sensory competence in fish.
