reef-associated; marine; depth range 111 - 130 m |
| Distribution: |
Western Pacific: Yap I. (Caroline Islands, Micronesia) and probably in the Marshall and Mariana islands. |
| Diagnosis: |
Dorsal spines (total): 14-14; Dorsal soft rays (total): 12-13; Anal spines: 2-2; Anal soft rays: 13-14. This species is distinguished by the following characters: Dorsal rays XIV,12-13, usually 13; anal rays II, 13-14, usually 13; pectoral rays 18-19; spiniform caudal rays 3; tubed lateral-line scales 16-17; gill rakers 6-7 + 20-21, total 26-27; body depth 1.68-1.86 in SL. The color when fresh is mahogany brown with bright yellow distally on spinous portion of dorsal fin; the soft portion of dorsal fin, caudal fin, and anal fin is bright yellow. |
| Biology: |
This species was observed at Yap (Caroline Islands), in a group of about a dozen individuals living among large (about 1-2 m) rock boulders just above the upper edge of a precipitous drop-off. A juvenile of approximately 4 cm SL was observed at a depth of 120 m, below the site where the type specimens were collected. Its color pattern was consistent with that of the adults (Ref. 59379). Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). |
