Morphology | Morphometrics
Northwest Pacific: Endemic to Japan. This name has been misapplied to Hippocampus sindonis (Ref. 30915). International trade is monitored through a licensing system (CITES II, since 5.15.04) and a minimum size of 10 cm applies.
Inhabits Sargassum belts near shore. Used in Chinese medicine (Ref. 12166). Length type OT refers to height (= TL - head length). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
