Short description Morphology | Morphometrics

A moderately-sloped head and bicuspid teeth in the outer row of the jaws place this species in Metriaclima. The absence of a black submarginal band in the dorsal fin in conjunction with a yellow gular region and branchiostegal membranes, and the light-brown colored females that have yellow fin margins distinguish M. glaucos from other members of Metriaclima, except M. chrysomallos and M. benetos. There are generally fewer teeth in the outer row of the lower left jaw (mode 16, range 14–19) of M. glaucos compared to M. chrysomallos (mode 22, range 15–25) and more compared to M. benetos (mode 12, range 9–13). On the basis of color pattern, females of M. glaucos cannot reliably be distinguished from those of most other members of the Aurora group, but they differ from those of M. xanthos new species by a shorter lower jaw (mean 30.8, range 28.8–32.8 % HL vs. mean 35.4, range 34.6–36.7 % HL) and from those of M. aurora by 8–11 vertical bars below the dorsal fin vs. 6 in M. aurora (Ref. 86409).

Biology     Glossary (e.g. epibenthic)

Found in intermediate habitat, where transition between rocks and sand occurs; 3-20 m deep; males hold territories mainly over sand near rocks and excavate beneath rocks to construct their spawning burrow; feeds on sediment-rich aufwuchs on rocks from which it rakes diatoms and loose algal strands (Ref. 86409).
