Etymology: Hippocampus: Greek, ippos = horse + Greek,kampe = curvature (Ref. 45335).

Issue
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 Ecology

Marine; demersal; non-migratory; depth range 12 - 60 m (Ref. 42735), usually 20 - 60 m (Ref. 42735).   Tropical

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

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.

Max length : 14.0 cm OT male/unsexed; (Ref. 42735)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (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).

Biology     Glossary (e.g. epibenthic)

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).

Estimates based on models

Preferred temperature (Ref. 115969): 23.7 - 28.8, mean 27.5 °C (based on 588 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00176 - 0.01132), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (11 of 100) .
