Crustacean biology and ecology

The stomatopods or mantis shrimps are malacostracan crustaceans of the subclass Hoplocarida. All extant hoplocarids belong to the order Stomatopoda and suborder Unipeltata. The Unipeltata comprises the extinct, stem-lineage sculdids, and the crown-group which includes the 19 extant families with more than 400 species. A cladistic analysis of all 20 families of the Unipeltata, rooted with four fossil outgroups, resulted in a single, fully resolved topology. The results largely support the existing five-superfamily classification. The Squilloidea, not the Bathysquilloidea, were the earliest derived crown-group superfamily. The Lysiosquilloidea and Erythrosquilloidea are derived as sister groups, which together are sister to the gonodactyloids. The Bathysquilloidea and Gonodactyloidea, however, were not monophyletic, supporting the erection of new superfamilies for the extinct Sculdidae and the extant Parasquillidae.
