Etymology: Aeoliscus: Derived from Aeolius, region from Asia Minor and Aeolus, the Greek god of winds (Ref. 45335). More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 42 m (Ref. 90102), usually - m (Ref. ). Tropical; 0°C - ; 32°N - 32°S, 38°E - 170°E
Indo-West Pacific: Tanzania (Ref. 51015) and Seychelles (Ref. 1623); then from southern Japan to New South Wales, Australia eastward to Vanuatu.

Morphology | Morphometrics
soft rays: 12. Recognized by hinged part of dorsal fin spine. Variable in color with habitat. Greenish-yellow with diffused stripe when in seagrass environment. Pale with black stripe when found on open substrate with white sand or rubble (Ref. 48635).
Form schools among the spines of Diadema or staghorn corals, and feed on minute crustaceans in the zooplankton. Remarkable for their strange body shape and swimming habit: the body is encased in an armor of thin, transparent plates; they swim in synchronized groups, each fish in a vertical position with the snout pointing downwards.

Bayesian length-weight: a=0.00282 (0.00106 - 0.00750), b=3.10 (2.86 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.48 se; based on food items.
Resilience (Ref. 120179
