The report assumes that the violent reaction of lobsters to boiling water is a reflex response (i.e. does not involve conscious perception) to noxious stimuli. [ 3 ] A European Food Safety Authority (EFSA) 2005 publication [ 82 ] stated that the largest of decapod crustaceans have complex behaviour, a pain system, considerable learning ...
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. [47] Global crayfish production is centered in Asia, primarily China.
Crayfish often find themselves in a conflicting situation where they are performing the highly motivated behavior of feeding when they suddenly receive a tail flip stimulus. Often, the crayfish will not perform a tail flip in this situation. This is because when a crayfish is actively feeding, the LGI itself is modulated by the behavior.
A shed carapace of a lady crab, part of the hard exoskeleton Body structure of a typical crustacean – krill. The body of a crustacean is composed of segments, which are grouped into three regions: the cephalon or head, [5] the pereon or thorax, [6] and the pleon or abdomen. [7]
Output of a computer model of underwater acoustic propagation in a simplified ocean environment. A seafloor map produced by multibeam sonar. Underwater acoustics (also known as hydroacoustics) is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries.
The structure can be only a few mud balls or can be as big as 40 cm in height, although this behaviour is seen in the entire genus, it is unknown why the burrowing crayfish do this. Additionally, during hot periods, the crayfish will plug the chimney, potentially to retain as much moisture as possible in their tunnelling systems. [5]

On the other hand, if a rat forages in the leaves and makes a sound that attracts a predator, the sound itself is a cue and the interaction is not considered a communication attempt. Air and water have different physical properties which lead to different velocity and clarity of the signal transmission process during communication. [4]
