Abstract

New behavior by spotted goatfish Pseudupeneus maculatus (Bloch, 1793) was observed. Spotted goatfish interacted by wriggling, touching, and twisting each other's barbels. Detailed observations suggest agonistic encounters of two males as interpretation of this behavior. This observed use of barbels by goatfish differs from their common uses in feeding, and from their previously noted use in courtship. This new behavior also suggests an interpretation for the latter.
