Etymology: Hippocampus: Greek, ippos = horse + Greek,kampe = curvature (Ref. 45335).
This species is a synonym of Hippocampus angustus Günther, 1870 according to Lourie et al., 2016 (Ref. 115213). This species record will be removed.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; non-migratory; depth range 12 - 60 m (Ref. 42735), usually 20 - 60 m (Ref. 42735). Tropical
Western Central Pacific: northern Australia (Dampier Archipelago, Western Australia to Northern Territory) and southern Papua New Guinea. International trade is monitored through a licensing system (CITES II, since 5.15.04) and a minimum size of 10 cm applies.

Morphology | Morphometrics
(total): 18. Pectoral fin rays usually 17; trunk rings 11; tail rings 30-35; spines long and sharp, spine above eye equal in length or longer than eye diameter, perpendicular to snout; nose-spine sharp, angled forward 45° to snout, anterior spines on superior tail longer than spaces between them (Ref. 42735).
Found on the continental shelf (Ref. 75154). Probably inhabiting more weedy areas (Ref. 42735). Maximum length is based on a straight-line length measurement from upper surface (ignoring spines) of first trunk ring, to tip of tail (Ref. 42735). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
