Three-spot Seahorse

The Three-spot Seahorse is a small marine fish identified by the two or three dark spots along the base of its dorsal fin and its bony, ring-plated body ending in a prehensile tail. Like other seahorses, it swims upright in a slow, deliberate manner, propelled by rapid undulations of its dorsal fin, and relies on camouflage to avoid predators. It feeds on small crustaceans and other zooplankton drawn in through its tubular snout.

Males carry fertilized eggs in a specialized brood pouch, giving live birth to fully formed young after gestation. As a predator of small invertebrates, it plays a modest role in regulating prey populations within its habitat.

This species inhabits coastal and inshore marine waters, typically found among seagrass beds, coral reefs, and soft sediment areas where it can anchor itself using its tail. Its known range spans the Indo-Pacific region, with recorded populations in Australia, Sri Lanka, Russia, India, and Japan.

The primary threat to this species is direct exploitation through fishing and harvesting, driven by demand for traditional medicine, curios, and the aquarium trade. Intentional hunting and trapping, both targeted and incidental through non-selective fishing gear such as trawl nets, further reduce numbers. These pressures are compounded by the species' low mobility and specific habitat requirements, which limit its ability to recover from population losses.

Conservation efforts include international trade regulation under CITES Appendix II, which requires permits for legal export, alongside regional fisheries management and habitat protection measures in parts of its range. Population trends remain in decline, and continued harvesting pressure suggests the species will likely remain vulnerable without stronger enforcement of existing trade controls and expanded habitat safeguards.
