Hoplocarida

Belongs within: Eumalacostraca.Contains: Squillidae, Gonodactyloidea, Lysiosquillidae. The Hoplocarida, including the mantis shrimps and their fossil relatives, are a group of malacostracan crustaceans bearing a small carapace and at least four free thoracic segments, together with a large abdomen ending in a tail fan. They differ from other living crustaceans in being active, rapacious hunters (Schram… Continue reading Hoplocarida

Belongs within: Malacostraca.Contains: Hoplocarida, Decapoda, Syncarida, Euphausiacea, Thermosbaenacea, Mysidacea, Isopoda, Cosinzeneacea, Cumacea, Tanaidacea, Amphipoda. The Eumalacostraca are a clade containing most of the familiar macroscopic crustaceans, such as amphipods, isopods and shrimps, characterised by rod-shaped appendages on thoracic segments 1–8 and association of the uropods and telson to form a tail fan (Ax 1999). Authors… Continue reading Eumalacostraca

The Grapsinae are a group of shore crabs in which the inner half of the suborbital margin is dominated by the suborbital crest, with the true infraorbital margin ending far from the inner end of the suborbital. The Sally lightfoot Grapsus grapsus is a common species on the Pacific coast of Central… Continue reading Grapsinae

Grapsoidea

Belongs within: Brachyura.Contains: Grapsinae, Varuninae. The Grapsoidea are a diverse group of crabs including both terrestrial and aquatic taxa, with the highest diversity in the marine intertidal and supratidal zones. The group is poorly defined but members tend to have a rectangular carapace. Terrestrial adults are found in the families Gecarcinidae and Sesarmidae though only… Continue reading Grapsoidea

Caprelloidea

Belongs within: Corophiida.Contains: Cyamus, Caprella. The Caprelloidea are a group of amphipods characterised by an extremely long basal segment on the urosome. Members include the Caprellidae, skeleton shrimp, which are small, elongate amphipods that are mostly found living among larger, camouflaging organisms such as bryozoans or seagrasses. Caprellinoididae resemble Caprellidae in body form but have… Continue reading Caprelloidea
