Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8; Vertebrae: 26. This species is distinguished from its congeners by the following characters: longitudinal scales 35-39; vertebrae 10 + 16 + 26; males with first dorsal fin high and falcate, non-filamentous, the longest seond and/or third spine(s) extending posteriorly to a space between bases of first and fourth second dorsal-fin branched rays when adpressed; fifth pelvic-fin segmented ray divided into 4 branches at its first (most proximal) segmenting point; pectoral-fin base and the prepelvic areas are naked; belly with small cycloid scales except for a narrow area around ventral midline or anterior half of ventral midline; longitudinal rows of sensory-papillae on cheek with no tranverse rows. Colouration: pectoral fin base with a black oval spot; temporal region with 2 red stripes, reaching posteriorly to, or around, dorsum of body below the first dorsal fin; caudal fin of males with 6-8 vertical deep-red or reddish-orange lines, in females, a black bifurcated blotch posteriorly at the base when alive or freshly collected (Ref. 123096).

Biology     Glossary (e.g. epibenthic)

A species that is amphidromous but landlocked in few freshwater reservoirs ok Okinawa-jima I. (Ref. 123096).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
