Morphology | Morphometrics
Elongate pelvic and caudal fin rays held body above the sediment. These rays appeared flexible when the fishes swam and stiff when they were perched on the bottom (Ref. 7460).
Eastern Atlantic: scattered records in the Mediterranean, off Cape Blanc in Mauritania, Azores, Gulf of Guinea and off equatorial Africa. Western Atlantic: USA to Gulf of Mexico including Caribbean and along Rio Grande Rise. Western Indian Ocean: Mozambique Channel. Elsewhere, equatorial western Pacific (Ref. 3590) and eastern Pacific (Ref. 58302).
Benthic (Ref. 58302). Found on lower slope, continental rise and oceanic ridges. Solitary. Perches on substrate with the aid of specialized fin rays (tripod), facing the current. Feeds on nektonic copepods and other small planktonic crustaceans. Synchronously hermaphroditic (Ref. 6688).
