Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7 - 9; Raggi dorsali molli (totale) : 12 - 14; Spine anali: 0; Raggi anali molli: 10 - 13. Caudal fin rounded. Head greyish-brown above, body lighter, with large, irregular dark spots forming cross-bands; stripes on all fins orange, pectoral tips white; oval black spot on hind part of spinous dorsal fin in males (Ref. 4698).
Found on sand-mud bottoms, mostly in brackish waters with bottom temperatures mostly near to or below 0°C and salinities of 10-15 ppt (Ref. 4698). Benthic (Ref. 58426). Feeds on small bottom invertebrates (Ref. 4698).
