This is the crayfish's primary mode of locomotion. [2] [3] The abdominal section of the crayfish is divided into seven segments. These segments are flexibly interconnected, forming the tail. Normally, the tail is held in an extended position to aid in maneuvering and balancing.
Crayfish can be cooked more humanely by first freezing them unconscious for a few hours, then destroying the central nervous system along their abdomen by cutting the crayfish lengthwise with a long knife down the center of the crayfish before cooking it. [46] Global crayfish production is centered in Asia, primarily China.
A 2014 study [72] on crayfish (Procambarus clarkii) tested their responses in a fear paradigm, the elevated plus maze in which animals choose to walk on an elevated cross which offers both aversive and preferable conditions (in this case, two arms were lit and two were dark). Crayfish which experienced an electric shock displayed enhanced ...
The common yabby (Cherax destructor) is an Australian freshwater crustacean in the Parastacidae family.It is listed as a vulnerable species [1] of crayfish by the International Union for Conservation of Nature (IUCN), though the wild yabby populations remain strong, and have expanded into new habitats created by reservoirs and farm dams.

Tunas such as the bluefin swim fast with their large crescent-shaped tails. The thunniform group contains high-speed long-distance swimmers, and is characteristic of tunas [5] and is also found in several lamnid sharks. [6] Here, virtually all the sideways movement is in the tail and the region connecting the main body to the tail (the peduncle).
