Description

The threadfin bass is a small grouper of the family Serranidae from the eastern Pacific. The species grows to about 28 cm and has a streamlined, pink to orangish body with yellow tints and elongated front dorsal rays. It inhabits rough bottoms and deeper reefs on the continental shelf. As a plankton feeder it feeds on small planktonic crustaceans and zooplankton picked from the water column above the reef; it often forms loose groups while doing so. Like many groupers it is probably a protogynous hermaphrodite. The species is harmless to humans.
