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.

"مقيم" تعني أن معظم الغطسات في هذه الوجهة ستُمكّنك من مشاهدتها؛ "موسمي" تعني أنها متواجدة بشكل موثوق خلال الأشهر المذكورة؛ أي شيء آخر فهو مكسب غير متوقع، وليس شيئًا يُعتمد عليه في التخطيط.

فهمها
الموئل: Seagrass beds, sponge and soft-coral gardens, mangrove edges, jetty piles, and rubble; anything grippable in gentle water.
النطاق: Temperate and tropical coasts worldwide, from Caribbean seagrass to Indo-Pacific muck and the cool bays of southern Australia.
السلوك: 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.
النظام الغذائي: Copepods, mysids, and other small crustaceans sucked through the tubular snout in enormous daily numbers.
الحجم: عادةً حوالي 0.1 m; موثَّق حتى عمق 0.35 m (height; the genus spans 1.5 cm pygmies to the 35 cm big-belly seahorse).
كيف تتصرف في حضوره
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.
الحفاظ على البيئة البحرية
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.
