Etymology: Hippocampus: Greek, ippos = horse + Greek,kampe = curvature (Ref. 45335);  grandiceps: From the Latin for large and head, in reference to its head which is proportionally larger than most other Hippocampus species..

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.

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 18. Pectoral fin rays usually 18; trunk rings 11; tail rings 32-33; head long, 94-103% of trunk length; head angled down to near trunk (Ref. 42735).

Biology     Glossary (e.g. epibenthic)

Collected from shallow water (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).
