Etymology: Halichoeres: Greek, als, alis = salt + Greek, choiros = pig (Ref. 45335); socialis: From the Latin socialis meaning social, in reference to the behavioral trait of this species of forming a true school, as distinct from a loose aggregation, when stressed (Ref. 46844).

Morfologie | Morfometrie
Dorsale stekels (totaal): 8 - 9; Dorsale zachte stralen (totaal): 11-12; Anale stekels 3; Anale zachte stralen: 11 - 12; Wervels: 25. Head and back gray-green with a narrow midlateral black-brown stripe from front of snout to caudal fin base, ending in a prominent black spot; second narrow brown stripe on lower side, the pale gray zone on the lower side between the two black-brown stripes bisected by a narrow white stripe; a narrow brown stripe on body at each side of base of dorsal fin, continuing middorsally on nape as a double stripe; occiput dark brown; the black caudal base spot rimmed with blue and white except posteriorly (Ref. 46844).
Inhabits shallow coral reefs over coral, sand, rubble or seagrass substrata (Ref. 46844). Forms tight coherent schools when chased (Ref. 80499). Feeds on zooplankton and forms evasive, compact schools when threatened (Ref. 46844).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00451 - 0.02020), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.4 ±0.45 se; based on food items.
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
