Sabre squirrelfish, Sargocentron spiniferum, common name giant squirrelfish and spiny squirrelfish, is a large Indo-Pacific species of squirrelfish belonging to the family Holocentridae. It is a species linked to the coral reef environment where it occupies a vast range of habitats: from atoll lagoons to reefs exposed to the open sea to coastal ones and even at depth. Juveniles are found among corals in shallow waters in environments sheltered from the force of the sea.
