Description

The common seadragon, also called the weedy seadragon, is a remarkable relative of the seahorses (Syngnathidae) and is endemic to the cool coastal waters of southern Australia. The species reaches about 46 cm and has an elongate, reddish body with yellow spots and purple-blue bands, and bears leaf-like appendages that camouflage it superbly among seaweeds and kelp. With a long, tubular snout it sucks up small crustacean plankton. The species has no prehensile tail. As in seahorses the male carries the eggs, here on the underside of the tail.
