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. They are, from head to tail:
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 ...
Hermit Crab young develop in stages, with the first two (the nauplius and protozoea) occurring inside the egg. Most hermit crab larvae hatch at the third stage, the zoea. In this larval stage, the crab has several long spines, a long, narrow abdomen, and large fringed antennae. Several zoeal moults are followed by the final larval stage, the ...
William Elford Leach erected the genus Megalopa in 1813 for a post-larval crab; a copepod post-larva is called a copepodite; a barnacle post-larva is called a cypris; a shrimp post-larva is called a parva; a hermit crab post-larva is called a glaucothoe; a spiny lobster / furry lobsters post-larva is called a puerulus and a slipper lobster post ...
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.
