Ökologie
seewasser riff-verbunden; standorttreu (Ref. 52884); tiefenbereich 0 - 44 m (Ref. 26893). Tropical
Western Atlantic: southern Florida, USA and Bahamas to northern South America. Including Antilles but absent in Jamaica (Ref. 26938).
Größe / Gewicht / Alter
Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 20.0 cm TL Männchen/unbestimmt; (Ref. 7251)
Rückenflossenstacheln (insgesamt) : 11; Rückenflossenweichstrahlen (insgesamt) : 16 - 17; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 14 - 16. Black spot on upper half of dorsal fin from sixth or seventh to ninth spines. Males have long, upcurved extension of maxillary bone marked with black bands (Ref. 26938). Females appear to lack the long double-banded maxilla, and there is only a single blackish band at the corner of the mouth (Ref. 13442).
Body shape (shape guide): elongated.
Inhabits sandy bottoms near coral reefs (Ref. 9710). Feeds on gastropods, crabs and fishes (Ref. 13628). Oviparous, mouthbrooding by males (Ref. 205). Monogamous and always in home-ranging pairs, that is they do not defend an exclusive territory (Ref. 52884).
