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).
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).
