| Cherax quadricarinatus Von Martens, 1868 |
The Australian red claw crayfish, also called Queensland red claw or just redclaw, Cherax quadricarinatus, is an Australian freshwater crayfish. Eduard von Martens (1831–1904 sometimes known as Carl or Karl Eduard von Martens, was a German zoologist For a topic outline on this subject see List of basic Australia topics. Crayfish, crawfish, crawdads, or crodgers are freshwater Crustaceans resembling small Lobsters to which they are closely It is found in permanent freshwater streams, billabongs and lakes on the north coast of the Northern Territory and northeastern Queensland. The Northern Territory is a federal territory of Australia, occupying much of the center of the mainland continent as well as the central northern regions Queensland is a state of Australia, occupying the north-eastern corner of the mainland continent Populations are also found in Papua New Guinea. Papua New Guinea (or ˈpæpjuːə in Tok Pisin: Papua Niugini) officially the Independent State of Papua New Guinea, is a country in Oceania Through translocation by humans, the range has spread down to southern Queensland and into the far north of West Australia. Western Australia is a state occupying the entire western third of the Australian continent. This tropical crustacean is very tolerant of environmental changes, and is primarily a detritivore. Detritivores, also known as detritus feeders or saprophages, are Heterotrophs that obtain Nutrients by consuming Detritus (decomposing
Redclaw colour ranges from dark brown to blue-green body and adult males have a distinct red patch on the outer margin of the claws. A claw is a curved pointed appendage found at the end of a toe or finger in most Mammals, Birds, and some Reptiles. They can reach up to 600 g. For other uses of the words gram or gramme see Gram (disambiguation. Redclaw are farmed commercially in Queensland and the Northern Territory, and are harvested at between 35 - 130 grams. Redclaw is a sought-after product with a delicate crustacean flavour. They are both non-aggressive in nature and highly fertile, and can therefore be bred in large numbers in captivity. Females, which are smaller than males, spawn approximately 300 olive green eggs which are fertilised from a spermatophore which the male has deposited at the base of her walking legs (periopods) during mating. Fertilised eggs are affixed to the females pleopods situated on the underside of the tale. Incubation takes approximately six weeks and the newly hatched juveniles rapidly become independent. The life cycle is simple and the animal reaches sexual maturity, and harvest size, somewhere between six to twelve months in optimal farmed conditions. Queensland Department of Primary Industries provides information to prospective farmers.
Some variaties of the species may be kept as pets but if the exuvia is removed from the tank after sheding, the crayfish has an 80 percent chance of death. Exuvia (alternative spelling exuvium, plural exuviae) is a term used in Biology to describe the remains of an Exoskeleton that is left after This is because the crayfish requires the calcium from its cast after sheding.
A subspecies known as rainbow lobster can be found off the coast of Thailand. In Zoology, as in other branches of Biology, subspecies is the Taxonomic rank immediately subordinate to a Species.
