The Rakali (Hydromys chrysogaster) is well adapted to hunt in the river and billabongs for fish, crustaceans and birds. It has a slim torpedo-like body, bushy whiskers for sensing prey and partially-webbed back feet for propulsion. The largest males grow to well over a metre in length from the nose to the white-tipped tail (see photo).
Like the platypus, rakalis come out from their burrows at dawn and dusk. They are easily disturbed and unless you are really quiet are rarely seen. When underwater they leave a trail of bubbles on the surface. Motion-sensing cameras set up in the wetlands regularly photograph them in the river and the Frog Pond.
