Etymology: Hypoatherina: Greek, hypo = under + Greek, atherina, the Greek name for the eperlane; 1770 (Ref. 45335).
Eponymy: Gilbert Percy Whitley (1903–1975) was a British-born Australian ichthyologist and malacologist. [...] (Ref. 128868), visit book page.
More on author: Whitley.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; pelagic-neritic; depth range 0 - ? m (Ref. 9760). Tropical
Western Pacific: New Guinea, northern and eastern Australia, Madang, Maron and Bougainville Islands. Possibly present over a wide range in Melanesian waters. Aso found around Lord Howe Island.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 12.5 cm TL male/unsexed; (Ref. 9760)
Dorsal spines (total): 6 - 9; Dorsal soft rays (total): 8 - 11; Anal spines: 1; Anal soft rays: 11 - 14. Lips absent. Ascending process of premaxilla, short and broad. Gill rakers in first lower gill arch 18-22. Midlateral scales 39-46. Predorsal scales 17-22.
Inhabits waters close inshore. Often seen to jump out of the water, especially after sunset when they appear as fluorescent streaks. At night they appear to aggregate with Atherinomorus capricornensis around One Tree Island (eastern Australia). Probably eaten by larger commercial species (Ref. 9760).

Estimates based on models
Preferred temperature (Ref.
123201): 24 - 29.3, mean 28.4 °C (based on 1430 cells).
Phylogenetic diversity index (Ref.

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.
