Actinopteri (ray-finned fishes) > Tetraodontiformes
(Puffers and filefishes) > Balistidae
Etymology: Xanthichthys: Greek, xanthos = yellow + Greek, ichthys = fish (Ref. 45335). More on authors: Jordan & Gilbert.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 6 - 130 m (Ref. 89972), usually - m (Ref. ). Subtropical; 0°C - ; 35°N - 31°S
Pacific Ocean: antitropical, from southern Japan, Hawaiian Islands, Clipperton Island, Revillagigedo Islands, southern California, Easter Island, and Pitcairn Islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm NG male/unsexed; (Ref. 89467)
soft rays: 26 - 29. Males are straw-yellow with each scale outlined in black creating a crosshatched appearance, and a red tail with neon submarginal blue band. Females are also crosshatched, but with a slate gray to blue ground color and tail.
Found mainly around oceanic islands and near reefs along the continental coasts (Ref. 9276). Found in schools in seaward reefs above drop-offs (Ref. 9710). Benthopelagic (Ref. 58302). Feeds on zooplanktons (Ref. 89972).
Males establish a territory for spawning and parental care but not for feeding (Ref. 116451). Only females tend the eggs but both parents keep guard (Ref. 116451).
