Environment: milieu / climate zone / depth range / distribution range
Ecologia
marino demersale; distribuzione batimetrica 3 - 50 m (Ref. 130224). Subtropical; 59°N - 20°N, 19°W - 36°E
Eastern Atlantic: North Sea to the Mediterranean, Morocco and Madeira. Reported from the Canary Islands (Ref. 3397).
Size / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 27.7 cm TL maschio/sesso non determinato; (Ref. 128593); common length : 10.0 cm TL maschio/sesso non determinato; (Ref. 4645); peso massimo pubblicato: 166.17 g (Ref. 128593)
Body elongate. Coloration grey-brown on the back and silvery-white on the sides. No spines in front of the eyes (Ref. 35388).
Littoral and benthic, on sandy, muddy or gravelly bottoms, from a few meters to about 150 m (in winter). Rest on the bottom, often buried with eyes and tip of first dorsal fin exposed. Considered as the most dangerous of the European weevers, both for its poison and for its frequent occurrence very near to beaches (Ref. 4675). There are venom glands on the first dorsal fin, which is totally black, and on the gill cover (Ref. 6790). Also Ref. 57406.
