Astacidea is an

crustaceans including lobsters (though not "lobsters" such as the spiny lobster etc.), crayfish
, and their close relatives.

Description

The Astacidea are distinguished from most other decapods by the presence of

Thaumastocheles, where the fifth pereiopod may have "a minute pincer".[2]

Distribution

Members of the infraorder Astacidea are found throughout the world – both in the oceans and in fresh water – except for mainland Africa and parts of Asia.[3]

Classification

Astacidea belongs to the group

sister clade to the infraorder Polychelida, a small group of crustaceans restricted to deep waters. The cladogram below shows Astacidea's placement within the larger order Decapoda, from analysis by Wolfe et al., 2019.[5]

Dendrobranchiata (prawns)

Pleocyemata

(crawling/walking decapods)

The infraorder Astacidea comprises five extant superfamilies, two of

Laurentaeglyphea neocaledonica) were formerly included here.[1]
