Etymology: Halicampus: Greek, als, alis = salt + Greek, kampe = bend (Ref. 45335). More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 20 m (Ref. 90102). Tropical; 30°N - 23°S
Western Pacific: Viet Nam to Fiji, north to Ryukyu Islands, south to Rowley Shoals and New Caledonia; Belau in Micronesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.3 cm SL male/unsexed; (Ref. 1602)
soft rays: 3. Superior trunk and tail ridges discontinuous; inferior trunk ridge ending at anal ring; lateral trunk ridge continuous with inferior tail ridge; body rings 13-15 + 30-32.
Adults inhabit reef flats to a depth of over 17 m. Easily recognized by color but secretive and not often seen (Ref. 48635). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Also seen in coral reefs in 1-20 m (Ref 90102).
