Cambarellus patzcuarensis is a small, threatened species of crayfish in the family Cambaridae.[1][2] It is native to Mexico and often kept in aquariums.[3]


It measures 4–5 centimetres (1.6–2.0 in) in total length, including claws. Most specimens found in the wild are brown, sometimes with a gray or blue tint. Cambarellus patzcuarensis var. "Orange" (Mexican dwarf crayfish, sometimes Mexican dwarf orange crayfish) is an orange-coloured mutation often held in aquariums, but this form is rarely found in the wild.[3]


The species is named after Lake Pátzcuaro, at an altitude of 2,035 metres (6,677 ft) in Michoacán, Mexico. As well as Lake Pátzcuaro, C. patzcuarensis also occurs in springs in Chapultepec, Opopeo and Tzurumutaro.[1]


C. patzcuarensis is listed as an endangered species on the IUCN Red List.[1]
