Both the weedy seadragon (Phyllopteryx taeniolatus) and leafy seadragon (Phycodurus eques) are close relatives of seahorses. Seadragons have extra decorative fins that help them blend with the floating seaweed in which they live.

What They Eat

The small size of the seadragon’s snout limits the food it can eat. Seadragons eat tiny sea creatures, mostly shrimp-like animals called mysids. They may suck in as many as 1,000 a day.

Where They Live

Seadragons exist in only a very small part of the earth’s oceans, relying on particular kelp (seaweed) forests off the southern coast of Australia.

What They Do

Seadragons swim slowly with nearly invisible movements of their fins but mostly go with the flow of the water among the sea plants they resemble.

How They’re Doing

Seadragons came perilously close to disappearing in the 1990s due to pollution and habitat loss. Australia has officially protected the populations, but pollution remains a threat.

  • Seadragons are extremely delicate. They can be injured even by the simple touch of a human hand.
  • When seadragons need additional camouflage, they clump together in a group that looks like a floating mat of seaweed.
  • As with other members of the seahorse family, male seadragons carry fertilized embryos.
  • Unlike seahorses, seadragons cannot use their tail for gripping.
