Information

Description:

Dorsal spines: 6; Dorsal rays (total): 9 (0ccasionally 10); Anal spines: 3; Anal rays: 38-43. Lateral-line scales 54–61; scales above lateral line to origin of dorsal fin 4.

Moderately full-bodied sweeper, laterally compressed. Dorsal profile of head convex. Snout short. Eye small for genus. Interorbital area slightly convex. Mouth strongly oblique, forming an angle of about 60° to horizontal axis of head and body, the slender lower jaw slightly protruding when mouth fully closed. Outer part of paired patch of small teeth anteriorly in lower jaw and narrow band of small teeth of upper jaw exposed when mouth fully closed. Maxilla usually reaching to below centre of eye.

Colour. Bronze to copper in life, suffused with yellowish green dorsally on head and body. Iris black with a bright yellow inner ring.

Size:

Maturity: Lm unknown. Range unknown. Max Length: 13.3cm SL.


Habitat and Ecology:

Shelters in aggregations in caves or beneath ledges by day. May also swim in small groups in the open, though close to the shelter of coral reef (depth 1-11m).


Fishery Status:

This species is not protected or subject to fishery regulations. Due to its small size it is rarely caught. This specimen was caught in a seine net.


Notes:

Pempheris is a very complex genus, with for example 34 new species from the western Indian ocean being described in 2015 (Randall & Victor 2015) including 3 species nominally endemic to Seychelles. However the physical characteristics of P. flavicycla are quite distinctive.
