Spotted Pipefish

Stigmatopora argus

The Spotted Pipefish is a ray-finned fish endemic to Australia, belonging to the Syngnathidae family, which also includes seahorses. It is characterized by its slender, eel-like body, typically green in color with distinctive black spots along its dorsal surface. This species can grow up to 27 centimeters in length. Divers can often spot them in shallow waters, as they are commonly found in bays and estuaries, often among seagrass or macroalgae. They have a prehensile tail that allows them to anchor themselves to vegetation. Spotted Pipefish primarily feed on small crustaceans such as copepods and mysids. They exhibit a unique reproductive behavior where the male carries the fertilized eggs in a brood pouch located under his tail. Males may start brooding at around 11.2 centimeters in total length. These pipefish are typically encountered at depths up to 8 meters, although they can occasionally be found among floating Sargassum offshore. The conservation status of the Spotted Pipefish is listed as Least Concern by the IUCN. Divers encountering this species can expect a harmless interaction, as they are not known to pose any threat to humans.
