Big-belly Seahorse
Hippocampus abdominalisAlso known as Pot-bellied Seahorse, Eastern Potbelly Seahorse
Big-belly seahorses are majestic marine giants of the shallow seas, instantly recognizable by their prominent, swollen abdomens and long, prehensile tails. They navigate kelp forests and seagrass meadows with delicate, upright grace, using their highly mobile eyes to track tiny drifting prey. During the breeding season, males inflate their brood pouches to perform elaborate courtship dances, eventually carrying and birthing hundreds of fully formed miniature offspring.

Safe to observe at a normal distance.
Protected under CITES Appendix II due to threats from habitat loss and targeted collection for traditional medicine and the aquarium trade.
Observe quietly from a respectful distance without touching, crowding, or removing them from their anchoring spots.- Look around structures: Search among jetty pylons, sponge gardens, and seaweed clumps where they anchor themselves.
- Avoid flash photography: Use ambient light to photograph them, as bright flashes can stress these sensitive fish.
- Maintain distance: Do not touch or attempt to handle them, as their protective skin layer is easily damaged.
