Species

Around 340,[2] see text

Caridina is a genus of freshwater atyid shrimp. They are widely found in tropical or subtropical water in Asia, Oceania and Africa. They are filter-feeders and omnivorous scavengers. They range from 0.9 to 9.8 mm (C. cantonensis) to 1.2–7.4 mm (C. serrata) in carapace length.

Taxonomy and species

Caridina serratirostris, a widespread freshwater species from the Indo-Pacific region
Caridina dennerli, one of several species restricted to the Indonesian island of Sulawesi
Caridina cantonensis is widely kept in aquariums and several color forms have been achieved through selective breeding

There is evidence for hybridization between sympatric taxa, requiring care when interpreting molecular phylogenetic analyses that do not use a large number of specimens.[3]

As of March 2022, the Integrated Taxonomic Information System lists the genus Caridina as having 340 species.[4] These include the following species:[5][6][7][8][9]

A number of phylogenetic studies have questioned the monophyly of Caridina.[12]

Threats and Conservation

As of March 2023, the IUCN Red List lists 56 Caridina species as threatened, with 18 listed as critically endangered, 5 listed as endangered, and 33 listed as vulnerable.[13] Of these, two (Caridina apodosis and Caridina yilong) are listed as possibly extinct and one (Caridina dennerli) is listed as possibly extinct in the wild.
