Morphology | Morphometrics
Vertebrae: 178 - 188. Slender species with 38-44 preanal pores, dorsal fin origin over middle of pectoral fin, and body color of minute, closely packed, dark spots that are more prominent above lateral line, widely spaced dark spots along edge of dorsal fin, white postorbital patches, a silver iris prominently edged with black, and dark peritoneal pigment ventrally on abdomen.
In dense colonies of about 6 individuals per square meter. Feeds on zooplankton (Ref. 33408, 89972). Diet mainly composed of calanoid copepods, gelatinous plankton, invertebrate pelagic eggs, siphonophores, decapod larvae, fish eggs, particles of organic matter and larvaceans. (Ref. 33447).

Estimates based on models
Preferred temperature (Ref. 115969
): 26.4 - 28.5, mean 27.6 °C (based on 12 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (35 of 100) .
