Description

The Australian grayling is a migratory freshwater fish (Retropinnidae) from southeastern Australia and Tasmania. The species grows to about 33 cm and has a slender, silver-grey body with an adipose fin and a characteristic cucumber smell. It grows up in rivers; the larvae wash to sea and return as juveniles. As an omnivore it eats algae, insects and small invertebrates. Through dams and habitat loss the species is protected. The fish is harmless to humans.
