Achelata

Southern rock lobster or crayfish Jasus edwardsii, copyright Stemonitis.

Belongs within: Reptantia.
Contains: Stridentes.

The Achelata, spiny and slipper lobsters, are a group of marine decapods characterised by the lack of chelae on most pereiopods.

Synapomorphies (from Dixon et al. 2003): Eyestalks with row of hairs alongside eye; second antenna greatly enlarged, basal articles of second antennae fused with epistome; pereiopods (except fifth) achelate. Carapace held to body by knob emanating from last thoracic somite; lineae absent; pleon with prominent hinges; pleurites pointed; tail fan soft distally; telson with fixed lateral spines. Phyllosoma larva present.
