Taille / Poids / Âge
Maturité: Lm ?  range ? - ? cm
Max length : 24.0 cm TL mâle / non sexé; (Ref. 11228)
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 11 - 13; Épines anales: 0; Rayons mous anaux: 8 - 10. Body brownish above, with 7 irregular blackish bars (Ref. 11228). Cheek usually not scaled to preopercular margin; membranous flap on anterior nostrils long and slender; pectoral fins not reaching a line connecting origins of dorsal and pelvic fins.
Body shape (shape guide): elongated; Cross section: circular.
Common on sand or sand-rubble areas of lagoon and seaward reefs to over 20 m depth (Ref. 1602, 9710, 48635). Benthic (Ref. 58302). Feeds on shrimps and small fishes (Ref. 89972). Frequently buries in sand leaving only eyes and nostrils exposed (Ref. 9710, 48635). Generally solitary (Ref. 1602). Sometimes in pairs or small groups (Ref 90102).
Cycle de vie et comportement reproducteur
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
Generally solitary, but up to four males may have been observed courting a single larger female. A courting male may station itself atop a female and puff out its opercula and spread its fins in a display of aggression towards other males (Ref. 37816).
