Spotted drum by Tom Byrnes

The spotted drum is an elusive, yet flamboyant, fish.

The spotted drum, Equetus punctatus, is a member of the family Sciaenidae.

This fish is a nocturnal plankton feeder, sparingly found in about 50-foot depths on reefs throughout the Caribbean. It quickly grows out of its spectacular juvenile stage, which sports a flamboyantly flowing black-and-white dorsal and tail fin.

The juvenile spotted drum is distinguished from the young jackknife fish by its black-spotted nose, as the latter has a black vertical dash.

It is not unusual for my divers to stop and admire one of these delicate fish do a swimming ballet in the confines of their lair, which is typically under a coral overhang.
