Common seadragon

The common seadragon or weedy seadragon (Phyllopteryx taeniolatus) is a marine fish related to the seahorse. Adult common seadragons are a reddish colour, with yellow and purple markings; they have small leaf-like appendages that resemble kelp fronds providing camouflage and a number of short spines for protection.[3][4] Males have narrower bodies and are darker than females.[4] Seadragons have a long dorsal fin along the back and small pectoral fins on either side of the neck, which provide balance.[5] Common seadragons can reach 45 cm (18 in) in length.

The common seadragon is the marine emblem of the Australian State of Victoria.[6]
