Introduction: Crayfish also known as Procambarus clariia are classified as a decapod crustaceans related to lobsters‚ crabs‚ and shrimp. They breathe through the gills as they are aquatic animals but they can survive for short time outside the water. They have a hard‚ calcified exoskeleton that must be shed as they grow. In front of the first abdominal segment locates crayfish heart in the dorsal portion of cephalothorax. Crayfish are poikilothermic as their internal temperature is proportional

Aspects of Decomposition: A Brief Overview Kyle Jackman Animals are complex creatures. The animal can perform such tasks as reproduction‚ digestion‚ and simply movement. This is leaving out the more basic functions of respiration‚ circulation‚ and various maintenance functions. All of these processes are very complex‚ from the superficial all the way to the chemical level. Decomposition is one of these processes. It is common belief in our society to believe that death is an event‚ but
