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.
