The Weedy Sea Dragon or Common Sea Dragon (Phyllopteryx taeniolatus) is a marine fish related to the seahorse. It is the only member of the genus Phyllopteryx. They occur in water 3 to 50 metres deep round the southern coastline of Australia, approximately between Port Stephens, New South Wales and Geraldton, Western Australia, as well as around Tasmania. Weedy Sea Dragons are named for the weed-like projections on their bodies that camouflage them as they move among the seaweed beds where they are usually found.
