In the aquarium, the sailfin plunderfish sits quietly on the bottom. The barbel is extended and occasionally twitched, mimicking a small worm. Histological examination shows that the barbel is highly innervated, with many tiny capsules resembling Pacinian corpuscles (a comomn type of pressure-sensitive sense organ amongst the vertebrates). Touching the barbel with forceps elicits a feeding lunge. This behavior implies that natural feeding may target mobile foragers, such as fish and amphipods.
