Leafy Seadragon

The leafy seadragon is a relative of seahorses found only in southern Australia. Its elaborate, seaweed-like camouflage makes it one of the most beautiful fish in the world.

Interesting facts

  • Its leaf-like appendages are for camouflage, not for swimming.
  • It moves using tiny, almost transparent fins on its neck and back.
  • As in seahorses, the male carries the eggs, attached to the underside of his tail.
  • It is the marine emblem of South Australia.
  • It has no teeth and sucks up tiny shrimp through its tube-like snout.
  • It is protected in Australian waters.

Behaviour

Leafy seadragons drift slowly among kelp and seagrass, swaying like plants. They are solitary except during breeding.

Breeding and young

The female transfers about 120–250 eggs to a brood patch under the male’s tail. He carries them for about four to six weeks until they hatch.

Threats and conservation

Collection for aquariums (now restricted), habitat loss and pollution.
