Leafy Sea Dragon

About

The leafy sea dragon (Phycodurus eques) is one of the most visually extraordinary fish in the ocean, and honestly one of the hardest to believe is real. Those elaborate, leaf-like appendages covering its body are purely for camouflage. They play no role in movement at all. Instead, this animal propels itself with near-invisible rippling fins, drifting through kelp beds and seagrass meadows along the southern coastline of Australia with uncanny patience. In the wild it feeds exclusively on tiny mysid shrimp and other small crustaceans, which it hoovers up through its long, pipe-like snout. Like its seahorse relatives, males carry the eggs during breeding, but unlike seahorses, leafy sea dragons attach their eggs to a patch of tissue on the underside of the tail rather than a brood pouch. In the aquarium world this species is almost exclusively the domain of public aquariums and a handful of licensed specialist keepers. Sourcing them legally is extremely difficult, as wild collection is heavily restricted in Australia, and captive breeding programs are limited. Even experienced marine keepers find them demanding. They require precise water conditions, live food, and considerable space to thrive.
