The Blue Crayfish (Cherax pulcher) is a species of crayfish indigenous to Hoa Creek in Western New Guinea, Indonesia. Although it was a popular species for over a decade in exotic pet stores across three continents for use in freshwater aquariums, it was not classified as a unique species until 2015.

EtymologyEdit

The specific name is derived from the Latin word pulcher, which means "beautiful". The name was chosen due to the species' bright coloration.

PhysiologyEdit

Blue Crayfish come in two known color variants: the primary colors are white, vivid blue and violet, while another is greenish-gray.

Males of the species measure 75–98 millimetres (3.0–3.9 in) in length, while females measure 83–90 millimetres (3.3–3.5 in) long. The body is slightly oval in shape. The species has notably large eyes.

The species is brightly colored, with a pink cephalothorax that fades into greenish-grey on the sides. The rostrum is a greenish-blue, and the pleon is dark blue or black, with pinkish-grey or cream coloration on the margins (in some individuals the pleon is greenish-grey with pink speckles). The tail fan is cream-colored or pink around the outside margin. The legs are blue, and the chelae are blue with varying intensities, with cream-colored or white margins.
