Actinopteri (ray-finned fishes) > Syngnathiformes (Pipefishes and seahorses) > Syngnathidae (Pipefishes and seahorses) > Syngnathinae
Etymology: Hippocampus:Greek, ippos = horse + Greek,kampe = curvature (Ref. 45335); hendriki:Named for Hendrik Kuiter in recognition of his keen interest in seahorses that he successfully conveyed to classmates and teachers..
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 16 - 25 m (Ref. 42735). Tropical
Western Central Pacific: Queensland, Australia. International trade is monitored through a licensing system (CITES II, since 5.15.04) and a minimum size of 10 cm applies.
Size / Weight / Age
Maturity: Lm? range ? - ? cm Max length : 10.4 cm OT (female)
Dorsalspines
(total): 0;
Dorsalsoft rays
(total): 17-18. Trunk rings 11; tail rings 34; subdorsal spines 3/0,1,0; nose spine of moderate length, angular in shape; spine above eye long, but shorter than eye diameter; spine behind eye of moderate size, followed by longer lateral head spine; coronet moderately high, sloping back in line with head profile; superior trunk ridge spines reduced to tubercles before dorsal fin in males, or entire ridge having irregular rugose parts with small spines on and in between junctions with rings (Ref. 42735).
Occurs over soft bottom of the continental shelf (Ref. 75154). 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). Minimum depth from Ref. 58018.
