Cambarellus chihuahuae

Chihuahua Dwarf Crayfish
(Cambarellus chihuahuae)

syn. -


Mexico: Ojo de Carbonera / Chihuahua

local name: -

size: (?)

extinction date: (?)

The Chihuahua Dwarf Crayfish was once thought to live only in a single spring (Ojo de Carbonera in the state of Chihuahua / Mexico), but was later found in three other springs within 3 km of the typus locality.

The reasons for its extinction are the same as in Alvarez's Dwarf Crayfish (Cambarellus alvarezi): pumping of groundwater for agriculture and thus the complete destruction of the ponds in which the crayfish species was living in.


The agricultural industry in this region itself has in the meantime collapsed - owing to a lack of groundwater!
