Etymology: Corythoichthys: Greek, korys, korythos = helmet + Greek, ichtys = fish (Ref. 45335).
The species Corythoichthys waitei Jordan & Seale, 1906 is considered as valid in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697) following Allen & Erdmann (2008: Ref. 74959).
Environment / Climate / Range
Marine; reef-associated; depth range 20 - 68 m (Ref. 9710), usually ? - 68 m (Ref. 37816). Tropical, preferred ?; 16°N - 23°S
Western Central Pacific: Borneo to Samoa, north to Marshall and Mariana Islands, south to Rowley Shoals and New Caledonia; throughout Micronesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 16.0 cm SL male/unsexed; (Ref. 1602)
Adults occur in shallow sandy or mixed sand, rubble, or coral areas of reef flats and lagoons, also sometimes on seaward reefs (Ref. 1602). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Males may be brooding at 6.5-7.0 cm SL. Usually in pairs or may form small aggregations (Ref 90102).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Monogamous mating is observed as both obligate and genetic (Ref. 52881). Male carries the eggs in a brood pouch (Ref. 205).
