Distribution

Widespread from South Africa to Fiji and Australia to Japan and India.

Habitat

Freshwater in rivers.

Remarks

Caridina typus revealed to be a species complex, all characterized by the lack of teeth on the dorsal margin of the rostrum. Three clades were recognized by Bernardes et al. (2017), named SUL, TAL and ARC. The latter one corresponds to the true C. typus , while SUL is C. jeani and TAL is C. zhujiangensis (publication in prep.).
