Abstract

The relative degree of aggressive behavior displayed by territorial male garibaldi, Hypsypops rubicunda is studied by placing a Linckia Columbia near the garibaldi's nest. Males guarding reproductive nests show significantly faster reactions to the presence of a Linckia starfish than those guarding nonreproductive nests. Other * qualitative observations indicate inpreased defensiveness of males with,reproductive nests. The relationship of these findings to the theory of territoriality is proposed as being primarily related to reproduction.
