Etymology: Halicampus: Greek, als, alis = salt + Greek, kampe = bend (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 3 - 25 m (Ref. 9710). Tropical
Indo-West Pacific: northern Red Sea (Gulfs of Suez and Aqaba), Indonesia off Sumbawa Islands, Queensland in Australia, Port Moresby in Papua New Guinea, New Britain Islands and Guadalcanal Islands in the Solomon Islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 48635)
soft rays: 4. Superior trunk and tail ridges discontinuous; inferior trunk ridge ending at anal ring; lateral trunk ridge continuous with inferior tail ridge; body rings 14 or 15 + 25-25. Colors vary with habitat, colorful on algae-rubble and dull on sand (Ref. 48635).
Adults inhabit reef flats where it is found in seagrass areas, among coral rubble and algae-covered rocks. Juveniles occur with round-leafed seagrasses on sand slopes, usually settling from pelagic state at about 8 cm long. Adults on sand or algae covered reefs to about 25 m depth (Ref. 48635). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Solitary or in pairs (Ref 90102).
