Common Seadragon facts | Weedy Seadragon | Amazing Animals

The common seadragon or weedy seadragon is a marine fish related to the seahorses. 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. Males have narrower bodies and are darker than females. Seadragons have a long dorsal fin along the back and small pectoral fins on either side of the neck, which provide balance. The common seadragon is the marine emblem of the Australian state of Victoria. It is endemic to Australian waters of the Eastern Indian Ocean, Southern Ocean and the South Western Pacific Ocean. It can be found approximately between Port Stephens and Geraldton, Western Australia, as well as Tasmania. It inhabits coastal waters down to at least 50 meters deep. It is associated with rocky reefs, seaweed beds, seagrass meadows and structures colonised by seaweed. These fish are slow-moving and rely on their camouflage as protection against predation; they drift in the water and with the leaf-like appendages resemble the swaying seaweed of their habitat. They lack a prehensile tail that enables similar species to clasp and anchor themselves. Individuals are observed either on their own or in pairs; feeding on tiny crustaceans and other zooplankton by sucking prey into their toothless mouths. Like seahorses, seadragon males are the sex that cares for the developing eggs. Females lay around 120 eggs onto the brood patch located on the underside of the males' tail. The eggs are fertilised and carried by the male for around a month before the hatchlings emerge. The young are independent at birth, beginning to eat shortly after. Common seadragons may live for up to six years. The Aquarium of the Pacific in Long Beach, California and the Tennessee Aquarium in Chattanooga, Tennessee in the US, and the Melbourne Aquarium in Melbourne, Australia are among the few facilities in the world to have successfully bred common seadragons in captivity, though others occasionally report egg laying.
