This cladogram is used across so, so many articles that I made it a template to 1) save time, 2) save space, and 3) more easily coordinate possible future changes to Decapoda. |

The Achelata is an infra-order of the decapod crustaceans, holding the spiny lobsters, slipper lobsters and their fossil relatives.
Description[edit]
The name "Achelata" derives from the fact that all the members of this group lack the chelae (claws) that are found on almost all other decapods (from the Ancient Greek ἀ-, a- = "not", χηλή, chela = "claw"). They are further united by the great enlargement of the second antennae, by the special "phyllosoma" form of the larva, and by a number of other characters.[2]
Classification and fossil record[edit]
The infraorder Achelata belongs to the group Reptantia, which consists of the walking/crawling decapods (lobsters and crabs). The cladogram below shows Achelata's placement within the larger order Decapoda, from analysis by Wolfe et al., 2019.[3]

Achelata contains the spiny lobsters (Palinuridae), the slipper lobsters (Scyllaridae) and the furry lobsters (Synaxidae, now usually included in Palinuridae),[4] as well as two extinct families, Cancrinidae and Tricarinidae.[1]
Both Palinuridae and Scyllaridae have a fossil record extending back to the Cretaceous.[5][6] The two fossil families contain a single genus each;[1] Tricarina is known from a single Cretaceous fossil,[7] while Cancrinos is known from the Jurassic and Cretaceous.[6] One estimate of the divergence between Achelata and its closest relatives places it at about 341 million years ago.[8]
