Etymology: Hippocampus: Greek, ippos = horse + Greek,kampe = curvature (Ref. 45335); biocellatus: From the Latin bi meaning two, and ocellus meaning eye, in reference to the double eye-like spot on its back.
This species is a synonym of Hippocampus planifrons Peters, 11877 according to Lourie et al., 2016 (Ref. 115213). This species record will be removed.

形態学 | 形態計測学
背面の脊椎 (合計): 0; 背鰭 (合計): 22-23; 肛門の骨 0; 臀鰭: 4 - 5. Anal fin rays divided at base; tail rings 36-38; subdorsal spines 4/0,0,1,1 or 5/0,0,1,1,1; nose ridge slightly raised, without a spine; spine above eyes moderately large, angled back and laterally outward; lateral head spine moderately large and recurved; coronet slightly raised, apex with 5 blunt diverging spines; upper shoulder-ring spine of small to moderate size, situated beside gill openings; central shoulder-ring spine of moderate size and directed laterally outward; superior trunk and tail ridges with broad thorn-like blunt spines, enlarged on some rings, at regular intervals; superior tail ridge with tubercle-like spines of moderate size, angled backward; trunk ridges followed by connecting tail ridges with spines and tubercles becoming gradually smaller posteriorly; lateral line with distinct pores, on trunk rings just above lateral ridge, continuing onto tail to 18th-23rd tail ring, each pore between raised papillae (Ref. 42735).
Adults inhabit shallow algae or weedy reef areas from the intertidal to about 20 m depth (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).
