King crabs are decapod crustaceans in the family Lithodidae that are chiefly found in deep waters. King crabs are not true crabs and are generally thought to be derived from hermit crab ancestors within the Paguridae, which may explain the asymmetry still found in the adult forms. This ancestry is supported by several anatomical peculiarities which are present only in king crabs and hermit crabs. Although some doubt still exists about this hypothesis, king crabs are the most widely quoted example of carcinisation among the Decapoda. Several species of king crabs, especially in Alaskan and southern South American waters, are targeted by commercial fisheries and have been subject to overfishing.
Odontodactylus is a genus of mantis shrimp, the only genus in the family Odontodactylidae. Mantis shrimp of the genus Odontodactylus can not only detect circular polarisation of light, but can also detect polarised light reflecting off their telson and uropods.
Pinnotheridae is a family of tiny soft-bodied crabs that live commensally in the mantles of certain bivalve molluscs and the occasional large gastropod mollusc species in genera such as Strombus and Haliotis. Tunicotheres moseri is commensal with a tunicate. The earliest fossils attributable to the Pinnotheridae date from the Danian.
Gonodactylidae is a family of mantis shrimp. It contains these genera:
Squillidae is a family of mantis shrimp, the only family in the superfamily Squilloidea. The type genus is Squilla. It is the stomatopod family with the most genera, as follows:
Eurysquillidae is a family of mantis shrimp. Formerly placed in the superfamily Gonodactyloidea, it has since been recognised that eurysquillids are closer to families in the Squilloidea, and so Eurysquillidae has been placed in its own superfamily, Eurysquilloidea. The family was first described in 1977 by Raymond Manning.
Tetrasquillidae is a family of mantis shrimp containing ten genera:
Raymunida is a genus of squat lobsters in the family Munididae, containing the following 11 species:
Gonodactylellus is a genus of mantis shrimp. The genus was first described by Raymond Manning in 1995.
The Camptandriidae are a family of crabs, with 38 species in 21 genera:
Acanthosquilla is a genus of stomatopod crustacean. The American carcinologist Raymond B. Manning named and first circumscribed the genus in 1963. As of 2018, the World Register of Marine Species recognizes the following eight species:
Alain is a genus of crabs belonging to the family Pinnotheridae, and was first described in 1998 by Raymond Manning. The type species of this genus was collected in Indonesian territorial waters.
Erugosquilla is a genus of crustaceans belonging to the family Squillidae. The genus was first described in 1995 by Raymond Brendan Manning. The type species is Erugosquilla massavensis(Kossmann, 1880).
Acanthosquilla crosnieri is a species of stomatopod crustacean in the Nannosquillidae family. It has been found in waters off the Marquesas, at depths of 0 - 100 m but more usually at 7 - 25 m, and was first described by the Australian carcinologist Shane T. Ahyong in 2002.
Alima is a genus of shrimps belonging to the family Squillidae, and was first described in 1817 by William Elford Leach.
Alima pacifica is a species of shrimp in the Squillidae family, and was first described in 2001 by Shane Ahyong.
Alain raymondi is a species of crab in the Pinnotheridae family. It was first described in 2008 by Ahyong and Peter Ng. The species epithet, raymondi, honours Ray Manning.
