Note
Color variants and behavior of scamp, Mycteroperca phenax, and gag, M. microlepis, are described from 64 submersible dives made on reef structures at depths between 20 and 100 m off the east coast of Florida from February 1977 to September 1982. These dives yielded 146 h of observations augmented with video and 35 mm photography. Both species display a variety of color phases associated with social behavior. They are expressed in each case by an aggressive, dominant territorial individual which displays to a group of smaller subordinates. Social hierarchy is evident in both species, with the alpha individual being a male in the gag and of undetermined sex in the scamp.
