Short description Morphology | Morphometrics

A moderately-sloped head and bicuspid teeth in the outer row of the jaws place this species in Metriaclima. Both males and females are light blue, fading to white ventrally, distinguishing them from all other members of Metriaclima, except M. callainos. Male M. nkhunguensis are distinguished from those of the similarly colored M. chrysomallos from the Gome population, M. estherae, and M. callainos, the latter two species of the sediment-free rocky habitat, by the yellow base of the pectoral fin (vs. no yellow pigment in males of the other three species). Female M. nkhunguensis are light blue, lighter than those of the only other known species with allblue females, M. callainos, which are a darker cobalt-blue (female M. estherae are either brown or orange/red). Metriaclima nkhunguensis is further distinguished from M. callainos by a shorter lower jaw (mean 31.2, range 29.4-34.1 % HL vs. mean 37.5, range 34.9-43.3 % HL) (Ref. 86409).

Biology     Glossary (e.g. epibenthic)

Occupies intermediate habitats at Minos and Nkhungu reefs; these reefs are shallow, less than 7 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).
