Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 7; Rayons mous dorsaux (Total) : 8; Épines anales: 0; Rayons mous anaux: 6. Pectoral fin very large and fan-like, with front 6 rays separated as small lobe (Ref. 26938).
Found on sand, mud or over rocks in sandy areas, exploring the bottom with the free part of the pectoral fins (Ref. 6544). Feeds primarily on benthic crustaceans, especially crabs, clams and small fishes. Neither anterolateral glandural groove nor venom gland is present (Ref. 57406).
