Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
marin récifal; non migrateur (Ref. 52884); profondeur 1 - 8 m (Ref. 89891). Tropical; 29°N - 10°N, 98°W - 59°W
Western Atlantic: southern Florida, USA and Bahamas to Central America, West Indies and Caribbean Islands.
Taille / Poids / Âge
Maturité: Lm ?  range ? - ? cm
Max length : 13.0 cm TL mâle / non sexé; (Ref. 7251)
Épines dorsales (Total) : 11; Rayons mous dorsaux (Total) : 15; Épines anales: 3; Rayons mous anaux: 15. Black spot in the dorsal fin is in the lower half of the fin and is usually located between the 6th and 9th spines; there is some brown pigment at the corner of the mouth but no black and white bands inside the maxilla (Ref. 13442).
Body shape (shape guide): elongated.
Adults inhabit an elaborate burrow, often fairly deep (12 inches), and with a terminal chamber; the vertical shaft lined with coral and shell fragments. Males are oral brooders (Ref. 5521). Monogamous and always in home-ranging pairs, that is they do not defend an exclusive territory (Ref. 52884).
