Leafy Seadragonリーフィーシードラゴン
Phycodurus equesLC— Least Concern
The leafy seadragon (Phycodurus eques) is a seahorse relative endemic to the cool coastal waters of southern Australia, from Wilsons Promontory in Victoria to Jurien Bay in Western Australia. Its body is covered in branching, leaf-like skin protrusions that camouflage it as drifting seaweed, while males carry and guard the eggs on a brood patch until they hatch. It is listed as Least Concern by the IUCN and serves as the official marine emblem of South Australia.
