COMMON (Weedy) SEADRAGON:
Common Seadragon, Phyllopteryx taeniolatus (Lacépède, 1804) The species is related to the seahorses. Unlike seahorses however, the seadragons do not have a pouch for rearing the young. Instead, male seadragons carry the eggs fixed to the underside of the tail. The standard name of the species in Australia is 'Common Seadragon', but many people know the fish by the name 'Weedy Seadragon'.
Leafy seadragons (Phycodurus eques) are exquisitely camouflaged fish. Belonging to the same family as seahorses and pipefish (Syngnathidae), they resemble these with their elongated snout and bony-plated body .
Leafy seadragons are yellowish-brown to green in colour, although they may vary depending on their age, diet or location.
The pectoral fins are located on the neck, and a dorsal fin runs along the seadragon's back. As their common name suggests, there are a number of leaf-like appendages along the body, which help to make these fish resemble the seaweed of their habitat. The eyes are located above the elongated snout and there are a number of defensive spines along the sides of the body
