Maturity: Lm 17.4 range ? - ? cm
Max length : 30.5 cm TL jantan/; (Ref. 59122); 25.0 cm TL (female); common length : 15.0 cm TL jantan/; (Ref. 3397); Umur maksimum dilaporkan: 7 Tahun (Ref. 72462)
Duri punggung (Keseluruhan (total)) : 4; duri punggung lunak (Keseluruhan (total)) : 8 - 10; Sirip dubur lunak: 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).
