Etymology: Hippocampus: Greek, ippos = horse + Greek,kampe = curvature (Ref. 45335). More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; non-migratory; depth range 1 - ? m (Ref. 30915). Tropical
Western Pacific: Japan and Viet Nam; occurrence along Chinese coast needs confirmation. Status: International trade is monitored through a licensing system (CITES II, since 5.15.04).
Length at first maturity / Size / Weight / Age
Maturity: Lm 5.5  range ? - ? cm
Max length : 8.0 cm OT male/unsexed; (Ref. 30915); common length : 5.0 cm OT male/unsexed; (Ref. 30915)
In Zostera seagrass beds; also in estuaries. Length type 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).
