Leafy Seadragon
Phycodurus eques
Overview
The leafy seadragon is a marine fish in the same family as seahorses. It is famous for its elaborate leaf-like camouflage, which makes it nearly indistinguishable from floating seaweed. It is the only member of the genus Phycodurus.
Fun Fact
The 'leaves' are not used for swimming but only for camouflage; they swim using tiny, nearly transparent fins that are hard to see.
Physical Characteristics
Elongated body covered in leaf-shaped appendages. Their color can change slightly depending on diet and location to match the surrounding seaweed.
Behavior & Ecology
Slow-moving and peaceful. They float like seaweed to avoid detection by predators, relying entirely on camouflage for protection.
Diet & Hunting Strategy
They lack teeth and swallow tiny crustaceans (mysid shrimp) and plankton whole by creating a suction with their long snout.
Reproduction & Life Cycle
Like seahorses, the male carries the eggs. The female deposits eggs onto a 'brood patch' under his tail, where they stay for about 8 weeks.
Human Interaction
A major icon of Australian marine life and a favourite for underwater photographers. They are protected by law.
