Hippocampus | Seahorse
LATIN NAME: Hippocampus
COMMON NAME: Seahorse (Hai Ma)
Species Profile
Seahorses, genus Hippocampus, are among the most recognizable fish in the sea, with their horse-like heads, prehensile tails and upright swimming posture. They live in shallow seagrass beds and mangroves around the world, and the dried fish, known as Hai Ma, is a classic item in Chinese tonic herbalism.
Seahorses are famous for male pregnancy: the female transfers her eggs to the male’s brood pouch, and he gives birth to fully formed young several weeks later.
Science & Biotechnology
Laboratory analysis of dried seahorse has identified amino acids, trace minerals and bioactive peptides, and preliminary studies have explored anti-fatigue and antioxidant effects, mostly in animal models. Their extraordinary biology, from camouflage to brood pouch development, also makes them important subjects in marine science.
Because wild seahorses are vulnerable, the entire genus is listed under CITES Appendix II, which regulates international trade. Captive breeding programs have expanded steadily and now supply a growing share of both the aquarium and tonic markets.
Uses & Benefits
In traditional practice, Hai Ma is considered a warming yang tonic, most often paired with meat in slow-simmered soups or infused in wine, and it is usually used in pairs, one larger and one smaller specimen, according to custom.
As with all animal tonics, tradition positions it as an occasional, small-quantity tonic rather than a daily supplement.
Source & Harvest
Good dried seahorse is complete and rigid with a curled tail, clear body rings and a clean sea smell; brittle fragments and sour or fishy odors signal poor handling. Size, species and dryness all affect grade and price.
Given the conservation status of seahorses, we recommend choosing documented, farmed or legally sourced material, and buyers should be aware that international shipment of seahorse products is regulated.
Our Take
Seahorse is a genuinely special tonic with a magical natural history behind it. Enjoy it the traditional way, in an occasional soup, and choose legally sourced, well-dried specimens.
