Rakali, the swimming rat.
- Rakali are also known as ‘water rats’, or ‘Australian water rat’ and are native to Australia and Papua New Guinea.
- Rakali are amphibious rats that have webbed back feet, waterproof fur, a flat head and a long and thick, white tipped rudder like tail.
- The scientific name of rakali is ‘Hydromys chrysogaster’ and they are one of the largest rodents native to Australia.
- Rakali live in fresh or salt water environments, and burrow and dig along riverbanks, lakes, and estuaries.
- The diet of a rakali includes water insects, mussels, fish, crustaceans, frogs, birds and their eggs.

- Rakali have bodies that grow to 23 to 37 cm (9 to 15 inches) in length, and have a total length of approximately 60 cm (23 inches), including the tail, and are grey, black or brown in colour, with an orange, cream, white or golden belly.
- The original name of ‘rakali’ was ‘water rat’ until an agreement occurred to change the name to the Australian indigenous name for the rat, ‘rakali’.
- Rakali are most commonly seen and observed a little before sunset and look like otters when swimming in the water.
- The typical litter of rakali is three to four babies, with up to five litters in a year.
- Rakali are preyed on by large fish, birds, cats and foxes.

It was an amazing experience seeing one so close to our home.
Yesterday,while out for my daily walk along the river a long thin animal that I had never seen before dived into the flooded water and swam off. I grabbed my phone to hopefully get a picture, I was impressed by its long thin white tipped tail. I managed a distant shot as it swam along and off and on the river bank. Icame home and googled Australiam water rat and there was my Rikali. I am 72 and never thought I would ever see one, so I am thrilled. I managed to get an albeit poor shot of it and am happy to send on if I knew who or where.
We saw one tonight at sunset swimming and diving along the wharf and under the bridge around the old punt launching area at Forster NSW
