Rakali
Hydromys chrysogasterAlso known as Water-rat, Australian Otter, Golden-bellied Water-rat, Rabe
Rakali are sleek, semi-aquatic rodents well adapted to life along Australian waterways with webbed hind feet, waterproof fur, and a distinctive white-tipped tail. Active mostly around dawn and dusk, these opportunistic predators forage for yabbies, fish, and aquatic invertebrates, often returning to favorite feeding platforms on logs or rocks to consume their catch. Females construct burrow systems in riverbanks where they raise litters of two to four young during spring and summer.
