Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 12; Raggi dorsali molli (totale) : 19 - 20; Spine anali: 3; Raggi anali molli: 14 - 16.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Usually solitary. Found in rocky, boulder strewn areas (Ref. 5227). Close relatives are known to pinch off and eat tube feet of sea urchins and other echinoderms. Also feed on crustaceans, worms and other small invertebrates (Ref. 4930). Because they live in relatively deeper waters, they are seldom collected, thus, rarely seen in the aquarium trade (Ref. 4930). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
