生態學
海洋 居於水底的; 深度上下限 1 - 440 m (Ref. 5968), usually 5 - 30 m (Ref. 27115). 16°C - 20°C (Ref. 27115); 66°N - 16°N, 42°W - 42°E
Eastern Atlantic: southern Iceland and Norway south to Mauritania, including the northern Mediterranean, Gibraltar, and Algeria, western Black Sea, Aegean and Adriatic Sea, Azores and the Canary Islands.
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 17.4  range ? - ? cm
Max length : 30.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 59122); 25.0 cm TL (female); common length : 15.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 3397); 最大年齡: 7 年 (Ref. 72462)
背棘 (總數) : 4; 背的軟條 (總數) : 8 - 10; 臀鰭軟條: 9. Gill opening dorsal. Usually antrorse (forward-pointing) tip at base of preopercular spine. Rays of second dorsal unbranched except for the last, which is divided at base (Ref. 232). Snout length 2-3 times the diameter of the eye (Ref. 35388).
Occurs on sand and muddy bottoms from sublittoral to 200 m (Ref. 6444) and to 400 m or more (Ref. 9900). Feeds on small invertebrates, mainly worms and crustaceans. Territorial, males aggressive with each other. Complex courtship behavior consists of 4 phases: courtship, pairing, ascending, releasing eggs and milt. Pelagic eggs and larvae (Ref. 5968). Minimum depth reported from Ref. 27115. Neither opercular spine gland nor anterolateral glandular groove with venom gland is present (Ref. 57406).
Complex courtship behavior with 4 phases: courtship, pairing, ascending, releasing eggs and milt (Ref. 5968).
