The decapod (crustaceans, such as a crab, lobster, shrimp or prawn) is made up of 20 body segments grouped into two main body parts: the cephalothorax and the pleon . [ 1 ] [ 2 ] Each segment may possess one pair of appendages , although in various groups these may be reduced or missing.
The Decapoda or decapods (lit. ' ten-footed ') is a large order of crustaceans within the class Malacostraca, and includes crabs, lobsters, crayfish, shrimp, and prawns.Most decapods are scavengers.
Haberma tingkok displays typical decapod anatomy. Ten limbs, arranged around the lower half of the carapace, are composed of eight multi-jointed legs used for mobility and two claws. The two equally sized claws are located on either side of the mouth and serve as the primary manipulation points for the crab. [5]

King crabs are decapod crustaceans of the family Lithodidae [b] that are chiefly found in deep waters and are adapted to cold environments. [2] [3] They are composed of two subfamilies: Lithodinae, which tend to inhabit deep waters, are globally distributed, and comprise the majority of the family's species diversity; [3] [4] and Hapalogastrinae, which are endemic to the North Pacific and ...
At the time of moulting, the crab takes in a lot of water to expand and crack open the old shell at a line of weakness along the back edge of the carapace. The crab must then extract all of itself – including its legs, mouthparts, eyestalks, and even the lining of the front and back of the digestive tract – from the old shell. This is a ...
Anomura (sometimes Anomala) is a group of decapod crustaceans, including hermit crabs and others. Although the names of many anomurans include the word crab, all true crabs are in the sister group to the Anomura, the Brachyura (the two groups together form the clade Meiura).
Pleocyemata is a suborder of decapod crustaceans, erected by Martin Burkenroad in 1963. [1] Burkenroad's classification replaced the earlier sub-orders of Natantia and Reptantia with the monophyletic groups Dendrobranchiata (prawns) and Pleocyemata.
