Caridina typus, also known as the Australian Amano shrimp, is a species of amphidromous atyid shrimp. It was first described by H. Milne-Edwards in 1837. It has a broad distribution in tropical freshwater habitats in the Indo-West Pacific region, with its western range extending to eastern Africa and its eastern range extending to Polynesia. It is commonly found in rivers and streams in coastal areas or on islands. C. typus is known to play a role in sediment distribution and shredding leaf litter, manipulating the environment using their pereiopods and setaceous chelae. The species is also an important component of the food web, both as scavengers and as prey items, and is considered a keystone species for the stream ecosystems it inhabits. According to Choy and Marshall, the species can be characterized by a "short, dorsally unarmed rostrum, the presence of epipods on the first four pairs of pereiopods, and the presence of an appendix interna on the endopod of the first pleopod of both sexes." It can be kept in captivity by aquarists as pets.
