Etymology: Hypoatherina: Greek, hypo = under + Greek, atherina, the Greek name for the eperlane; 1770 (Ref. 45335).
Eponymy: Dr Clifford Adrian Barnes (1905-1995) was an American marine scientist who was Professor of Oceanography at the University of Washington, Seattle (1947–1973) his alma mater and Professor Emeritus after retirement. [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 0 - 5 m (Ref. 86942). Tropical; 12°N - 20°S
Indo-Pacific: East Africa to the northern Cook Islands, north to New Guinea and the Marshall Islands, south to northern Australia, New Caledonia and Fiji.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 10.0 cm TL male/unsexed; (Ref. 48635); common length : 4.0 cm TL male/unsexed; (Ref. 2871)
Dorsal spines (total): 6 - 8; Dorsal soft rays (total): 8 - 12; Anal spines: 1; Anal soft rays: 12 - 17. Ascending process of premaxilla long and slender; ramus of dentary highly elevated posteriorly; midlateral band wide, broadest between anus and anal fin (Ref. 9760). First dorsal fin above middle of body; second dorsal fin originates behind the beginning of the anal fin; mid-lateral scales 40-43; transverse scales 5; predorsal scales 16-19 (Ref. 2334). Midlateral band width 2.3-3.3 in body depth (Ref. 37816).
Inhabits lagoons and along shorelines of outlying islands (Ref. 3302). During daylight, schooling fish may be periodically seen to jump out of the water to avoid predators. They are also easily attracted to light. The fish are gravid at about 4-4.5 cm SL by July in the northern hemisphere. Because of their large numbers, they are probably important as forage food for larger fishes (Ref. 9760).

Estimates based on models
Preferred temperature (Ref.
123201): 26.8 - 29.3, mean 28.6 °C (based on 1816 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00240 - 0.01320), b=3.15 (2.95 - 3.35), in cm total length, 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.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 127 [68, 248] mg/100g; Iron = 0.732 [0.406, 1.349] mg/100g; Protein = 19.5 [17.2, 21.8] %; Omega3 = 0.125 [0.054, 0.317] g/100g; Selenium = 16.1 [7.2, 38.6] μg/100g; VitaminA = 192 [57, 585] μg/100g; Zinc = 1.94 [1.27, 2.85] mg/100g (wet weight);
