As the name Decapoda (from the Greek δέκα, deca-, "ten", and πούς / ποδός, -pod, "foot") implies, ten of these appendages are considered legs. They are the pereiopods, found on the last five thoracic segments. [2] In many decapods, one pair of these "legs" has enlarged pincers, called chelae, with the legs being called ...

Decapod, (order Decapoda), any of more than 8,000 species of crustaceans (phylum Arthropoda) that include shrimp, lobsters, crayfish, hermit crabs, and crabs. The presence of five pairs of thoracic legs (pereiopods) is the basis for the name decapod (from the Greek meaning “10 legs”).
Les Decapoda sont des animaux principalement carnassiers, charognards ou détritivores. La plupart sont marins. Certains, comme les écrevisses, vivent en eau douce et d'autres, comme le crabe de cocotier, mènent une existence terrestre, dans des endroits humides.
Crab, any short-tailed member of the crustacean order Decapoda (phylum Arthropoda)—especially the brachyurans (infraorder Brachyura), or true crabs, but also other forms such as the anomurans (suborder Anomura), which include the hermit crabs. Decapods occur in all oceans, in fresh water, and on.
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.
Abstract. This chapter describes the taxonomy of the Decapoda, the most species-rich order of Crustacea, with over 14,500 described extant species worldwide, commonly called shrimps, prawns, lobsters, or crabs. Decapods exhibit a vast diversity in shape, size, and colour.
11 juin 2018 · decapod (dĕk´əpŏd´) (Gr.,=10 feet), name for invertebrate animals of the crustacean [1] order Decapoda (phylum Arthropoda [2]) including the crabs, the lobsters and crayfish, and the true shrimps, all having five pairs of legs.
Although the familiar terms "shrimp," "lobster," and "crab" have no formal taxonomic meaning, they do represent three distinct and recognizable body plans. Of the shrimplike forms, the Dendrobranchiata and the Caridea are the most familiar; they include all commercially harvested shrimps and prawns.
