Caridina is a genus of freshwater Atyidae Caridea. They are widely found in tropical or subtropical water in Asia, Oceania and Africa. They are filter feeding and omnivorous . They range from 0.9 to 9.8 mm ( C. cantonensis) to 1.2–7.4 mm ( Caridina serrata) in carapace length.
Taxonomy and species
There is evidence for hybridization between
sympatric taxon, requiring care when interpreting molecular phylogenetic analyses that do not use a large number of specimens.
As of March 2022, the Integrated Taxonomic Information System lists the genus Caridina as having 340 species.[Klotz, Werner, et al. "Lake Poso's shrimp fauna revisited: the description of five new species of the genus Caridina (Crustacea, Decapoda, Atyidae) more than doubles the number of endemic lacustrine species." ZooKeys 1009 (2021): 81.]
