Description synthétique
Clés d'identification | Morphologie | Morphométrie
Adults are found near rocks, mainly in eel-grass beds (Ref. 4742). Mainly solitary (Ref. 4742). Nest of seaweed built by male (Ref. 4742). Feed on mollusks, bivalves, gastropods, shrimps, sea-urchins and hydroids (Ref. 4742). Males grow faster than females (Ref. 4742). Oviparous, distinct pairing during breeding (Ref. 205).
Oviparous, distinct pairing during breeding (Ref. 205). Each male builds a nest of seaweed for one or two females to spawn in (Ref. 4742).
