New Species of Freshwater Crayfish Discovered by Czech Researchers

The previously unidentified species, Cherax pulverulentus, was found in a pet trade shipment and originates from Papua New Guinea.

Czech scientists identified a new crayfish species, Cherax pulverulentus, after ordering specimens from a major pet trade supplier.
The species, native to freshwater rivers in Papua New Guinea, had been exported globally for over 20 years under various trade names like 'Hoa Creek' and 'Blue Moon.'
Genetic analysis revealed that the DNA of Cherax pulverulentus differs by at least 2% from that of related crayfish species, confirming its unique classification.
The crayfish is characterized by its smooth body, large eyes, and distinctive spotted coloration, with two primary color variations: turquoise with purple spots and darker shades ranging from blue to black.
The species has also been found in unexpected locations, such as a thermal spring in Hungary, likely due to discarded aquarium specimens, though its natural behavior remains largely unknown.
