Etymology: Stenatherina: Greek, stenos =narrow + Greek, atherina, the Greek name for the eperlane; 1770 (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; depth range 1 - 20 m (Ref. 86942). Tropical, preferred ?; 19°N - 20°S
Pacific Ocean: Sumatra and the northern Cook Islands, north to the Philippines, Caroline Islands, and Marshall Islands, south to Fiji.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 11.0 cm TL male/unsexed; (Ref. 9760)
Morphology | Morphometrics
(total): 5 - 8;
soft rays: 9 - 12. Vomerine teeth forming a characteristic T pattern. Ascending process of premaxilla long, extending past orbit into interorbital space; lateral process very long and pungent. Gill rakers long and slender, longer than half the diameter of pupil. Interdorsal scales 8-10. Distinct crescentic mark present on snout immediately in front of eye; upper part of midlateral band terminating as half crescent on upper lobe of caudal fin.
Preferred habitat appears to be deeper enclosed atoll lagoons, reefs, coastal waters and harbors. May gather in schools at night when attracted to light but generally not found in very large numbers. May be taken as food by larger commercial species (Ref. 9760).

Bayesian length-weight: a=0.00525 (0.00232 - 0.01188), b=3.11 (2.91 - 3.31), 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. 69278
