The dwarf cassowary (Casuarius bennetti), also known as Bennett's cassowary, little cassowary, mountain cassowary or muruk, is the smallest of the three species of cassowaries.
The dwarf cassowary is a large bird but is smaller than other living cassowaries (the southern cassowary and northern cassowary). It is between 99 and 150 cm long and weighs between 17.6 and 26 kg. It is a flightless bird with hard and stiff black plumage, a low triangular casque, pink cheek and red patches of skin on its blue neck. Compared to other cassowaries, the dwarf cassowary is shorter, with a tarsi length of 24.5 cm, with a slightly smaller bill, at 11 to 12.2 cm. The feet are large and powerful, equipped with dagger-like claws on the inner toe. Both sexes are similar. Females have longer casques, brighter bare skin colour and are larger in size.
