Family Serranidae

Groupers & Basslets

This is a large and diverse family of carnivores from warm and temperate seas worldwide.  They have large, upturned mouths and continuous dorsal fin.

Anthias and Basslets

Basslets and Anthias are among our favorites.  These little groupers are quite rare in Hawai'i at deeper scuba depths and normally shy away from cameras.  They feed upon zooplankton at current-swept ledges, pinnacles and wrecks.  Males maintain harems of smaller, somewhat less-colorful females.  Four species most likely to be seen by divers are shown here; several more live in very deep water.
