Etymology: Plesiops: Greek, plesios = near + Greek, ops = appearance (Ref. 45335); auritus: From the Latin 'auritus' (noun in apposition), referring to the dark spot at the upper edge of the opercle and appears to be eared..
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 15 m (Ref. 90102). Tropical
Indo-Pacific: known only from Sri Lanka to the west coast of the Malaysian Peninsula near Phuket, and south along the western coast of Sumatra to north of Java
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.6 cm SL male/unsexed; (Ref. 27772)
Adults occur in coral heads, on reefs or in rocky areas, to depths of 15 m, but often in shallower water (Ref. 27772). Eggs are guarded by the male parent (Ref. 205).
