Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt): 11; Rückenflossenweichstrahlen (insgesamt): 15; Afterflossenstacheln 3; Afterflossenweichstrahlen: 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).
Inhabits an elaborate burrow, often fairly deep (12 inches), and with a terminal chamber; the vertical shaft lined with coral and shell fragments. An oral brooder (Ref. 5521).
