Reef Fish
Seahorses
Hippocampus · Bony fish — genus Hippocampus, family Syngnathidae (seahorses and pipefishes); genus-level overview of roughly 50 species
Seahorses ask divers to recalibrate. Upright posture, prehensile tail, independently swiveling eyes, and a brood pouch in which the male carries and births the young — nothing else on the reef works quite this way. Roughly fifty species make up the genus, from thumbnail pygmies to the big-belly seahorse of southern Australia, most of them ambush feeders sucking tiny crustaceans through tubular snouts. They are weak swimmers and strong holders: find one gripping a sponge, sea whip, or net fragment and it will likely be within meters of that spot next month. That site fidelity, plus a huge dried-animal trade, is why the entire genus has sat on CITES Appendix II since 2004. Move slowly, keep lights short, and let the animal keep its grip — a dislodged seahorse spends real energy getting home.

最佳月份一览
深入了解
栖息地: Seagrass beds, sponge and soft-coral gardens, mangrove edges, jetty piles, and rubble; anything grippable in gentle water.
分布范围: Temperate and tropical coasts worldwide, from Caribbean seagrass to Indo-Pacific muck and the cool bays of southern Australia.
习性: Weak swimmers and strong holders — a prehensile tail anchors each animal to a home patch it may keep for months; the male incubates eggs in a brood pouch and gives birth to live young.
食性: Copepods, mysids, and other small crustaceans sucked through the tubular snout in enormous daily numbers.
体型: 通常约 0.1 m; 记录深度可达 0.35 m (height; the genus spans 1.5 cm pygmies to the 35 cm big-belly seahorse).
与它相处时的行为守则
Approach slowly on the animal's level, keep lights brief and angled, and never detach a seahorse from its holdfast; many sites cap photo time per group.
保育
All Hippocampus species are on CITES Appendix II; several are threatened and many are Data Deficient, with dried-trade and bycatch pressure far exceeding aquarium collection.
