Common Seadragon

Phyllopteryx taeniolatus

In terms of size and biology, the Common Seadragon is generally smaller than its close relative, the Leafy Seadragon, reaching only about 30 cm in length. It has an elongated, slender body, and its leaf-like appendages provide it with excellent camouflage in its aquatic environment. It also has a long, snout-like mouth that it uses to suck up its small prey.

The Common Seadragon, also known as the Weedy Seadragon, is a species of fish that belongs to the Syngnathidae family, along with Seahorses and Pipefish. It is known for its elaborate, leaf-like appendages and vibrant colors, which help it blend in with its surroundings.

The Common Seadragon is found in the waters of southern and western Australia, where it inhabits shallow, coastal waters and seagrass beds. It can be found along the southern coast of Western Australia, as well as in areas such as Victoria, South Australia, and New South Wales.


The diet consists primarily of small crustaceans such as mysids and amphipods. It uses its long, snout-like mouth to suck up its prey, and it has specialized gills that allow it to filter out small particles from the water.

In terms of behavior, the Common Seadragon is a relatively slow-moving fish that relies on its camouflage for protection. It is a solitary creature and tends to move slowly through the water, using its leaf-like appendages to blend in with its surroundings.


The Common Seadragon is scientifically known as Phyllopteryx taeniolatus, and is the only species in the Phyllopteryx genus. It is a member of the Hippocampinae subfamily within the Syngnathidae family, and is closely related to seahorses and pipefish

Despite its name, these unique fish are considered to be vulnerable to extinction due to habitat loss and pollution.
