Discovering the aquatic life on and under the Swan-Canning River in Perth, Western Australia. Where does the freshwater ecosystem transition into a marine one? Lets find out!

Includes the Swan, Canning, Avon, Helena etc rivers and their tributaries. Aquatic-related submissions from all watercourses directly connecting to the Swan-Canning are welcome.

Submissions must be aquatic in nature. These may be creatures that are fully aquatic- eg fish; spend much of their life in the water- eg ducks, frogs, rakali; or spend most of their life intrinsically entwined with the water- eg dragonflies, osprey. Please also have a look at the plants in the water! These are very important to the river ecosystem so snap a few pics of those too.

Please exclude non-aquatic life that lives adjacent to the river- eg parrots, possums. less ↑
