Knowra Crayfish Crayfish Crayfish are decapod crustaceans, usually living in freshwater, with elongated bodies and large front claws. They resemble small lobsters and are also called crawfish or freshwater lobsters.
Decapoda : An order of crustaceans characterized by five pairs of walking legs. Crayfish belong to this order alongside crabs, lobsters, and shrimp.
Autotomy : The voluntary shedding of a body part, often as a defense against predators. Crayfish can shed a limb to escape a grasp and later regenerate it.
Crayfish aquaculture : The farming of crayfish for food, stocking, or other commercial uses. Aquaculture raises crayfish in ponds and other managed systems.
Invasive species : A non-native organism whose establishment and spread cause ecological, economic, or other harm. Crayfish introductions can turn some species into damaging invaders.
Red swamp crayfish : A burrowing crayfish native to the south-central United States and northeastern Mexico, widely introduced elsewhere. This highly adaptable species is both commercially farmed and invasive in some regions.
Astacoidea : A superfamily of freshwater crayfish found primarily in the Northern Hemisphere. Many familiar Northern Hemisphere crayfish belong to this lineage.
Regeneration (biology) : The regrowth or replacement of lost or damaged body parts in living organisms. Lost crayfish legs and claws can regrow across successive molts.
Louisiana Creole cuisine : A cuisine of Louisiana shaped by French, Spanish, African, Caribbean, and other influences. Crawfish are central ingredients in dishes such as étouffée and crawfish boils.
Signal crayfish : A North American crayfish introduced to Europe and other regions beyond its native range. Its spread in Europe has contributed to declines of native crayfish.
Murray crayfish : A large freshwater crayfish native to rivers of southeastern Australia. Its size, habitat needs, and declining populations make it a notable Australian case.
