Cherax boesemani is a relatively large crayfish, adult body length is 5–6 in (13–15 cm). [2] Variable blues, reds, and oranges are the predominant carapace colours, which has led to extensive selective breeding to create new commercial strains , with names such as Blue Moon , Supernova , Papuan red , tricolor and Red Brick .
These crayfish often burrow alongside the riverbank when breeding and hibernating. Studies have shown that Cambaroides japonicus preferentially select artificial burrows based on their relative size, leading to the conclusion that burrow patterns are related to size characteristics of the organism.

Murray crayfish have large white claws and a dark olive/grey/black carapace, all of which are covered in short robust spikes. [2] In small individuals, the claws are green and yellow. [2] The crayfish begin to breed when they are 15–20 cm (6–8 in) long, which takes between 6 and 9 years. [2]
Crayfish usually have limited home range and so they rest, digest, and eliminate their waste, most commonly in the same location each day. Feeding exposes the crayfish to risk of predation, and so feeding behaviour is often rapid and synchronised with feeding processes that reduce such risks — eat, hide, process and eliminate.
The Everglades crayfish [2] (Procambarus alleni), sometimes called the Florida crayfish, the blue crayfish, the electric blue crayfish, or the sapphire crayfish, is a species of freshwater crayfish endemic to Florida in the United States.
The genus Cambarus is the second largest freshwater crayfish genus inhabiting the Northern Hemisphere, with only sixty fewer species than the genus Procambarus. [2] Though Cambarus are varied across species, the two terminal elements that make up the male form I gonopod form ninety degree angles with the central appendage, allowing for their identification.
