Male seadragons are dedicated fathers that brood and nourish around 250 to 300 fertilised eggs in a brood patch on the underside of their tails. When these eggs are deposited, the seadragon’s skin forms a cup around each of them. After 30 to 38 days, the eggs hatch, and the young rely on their yolk sacs for two to three days before beginning to hunt independently.

Seadragons have long, tubular, toothless mouths that can suck up a prey whole by expanding a joint in the lower snout. Their keen eyes can move independently of each other, aiding in precise hunting. Using pivot feeding, they rapidly rotate their snouts with the help of elastic recoil of tendons to catch small, fast-moving prey with remarkable accuracy.

Found only around Australia, this species is affected by the ongoing degradation and loss of coastal habitats. Seagrass meadows and coral reefs are declining in both quality and size due to human activities, threatening the survival of Weedy Seadragons that rely on them for shelter and protection.
