Sargocentron spiniferumSabre Squirrelfish | Giant Squirrelfish | Longjaw Squirrelfish | Spinecheek Squirrelfish | Spiny Squirrelfish
Large, red with distinctive pale markings on face giving a 'skeletal' apperance, and a long, thick spine on cheek before gill cover. Pectoral, pelvic and anal fins and lower lobe of tail yellow. Usually hiding well back in caves or underledges. Lack of a white tail base distinguishes it from smaller but similar S. caudimaculatum (Whitetail Squirrelfish).
