Tantulocarida is a highly specialised group of parasitic crustaceans that consists of about 33 species, treated as a class in superclass Multicrustacea. They are typically ectoparasites that infest copepods, isopods, tanaids, amphipods and ostracods.
Cumoniscidae is a family of crustaceans in the class Tantulocarida, classified under the superclass Multicrustacea. The family was previously known as Deoterthridae, but Cumoniscidae was determined to be senior subjective synonym.
Thompsonia is a genus of barnacles which has evolved into an endoparasite of other crustaceans, including crabs and snapping shrimp. It spreads through the host's body as a network of threads, and produces many egg capsules which emerge through joints in the host's shell.
Epicaridea is a former suborder of isopods, now treated as an infraorder in suborder Cymothoida. They are ectoparasites that inhabit other crustaceans, namely ostracods, copepods, barnacles and malacostracans. Epicarideans are found globally. Epicaridea are generally less well researched than other isopods.
The Cirolanidae are a family of isopod crustaceans, including these genera:
Cymothoida is the name of a suborder of isopod crustaceans with a mostly carnivorous or parasitic lifestyle. It contains more than 2,700 described species in four superfamilies. Members of the suborder are characterised by their specialised mouthparts which include a mandible with a tooth-like process which is adapted for cutting or slicing.
Pruvotinidae is a diverse taxonomic family of cavibelonian solenogasters, shell-less, worm-like marine mollusks.
The Bopyridae are a family of isopod crustaceans in the suborder Cymothoida. There are 1223 individual species contained in this family. Members of the family are ectoparasites of crabs and shrimp. They live in the gill cavities or under the carapace where they cause a noticeable swelling. Fossil crustaceans have occasionally been observed to have a similar characteristic bulge.
Cancricepon is a genus of isopod crustaceans in the family Bopyridae. It has been synonymised with Merocepon Richardson, 1910.
The Dajidae are a family of marine isopod crustaceans in the suborder Cymothoida. The original description was made by Giard and Bonnier in 1887. Members of this family are ectoparasites of krill. They resemble a fleshy growth on the krill's back, and make the host look as if it is wearing a rucksack. These genera are included in the family Dajidae:
The Entoniscidae are a family of marine isopod crustaceans in the suborder Cymothoida. Members of this family are parasites of brachyuran and anomuran crabs, living in their hosts' haemocoel. A small chitinised hole develops through the host's exoskeleton through which the isopod can communicate with the environment. The female isopod bears little resemblance to any free-living isopod, but the morphology of the larvae show their taxonomic affiliations.
Parasymmetrorbione is a genus of isopod containing a single species, Parasymmetrorbione bicauda.
Harriet Richardson Searle was an American carcinologist. She was known as the first lady of isopods and was one of the first female carcinologists, with only Mary Jane Rathbun before her.
Hugo Frederik Nierstrasz was a Dutch zoologist, known for his research in the fields of malacology and carcinology.
The clade Multicrustacea constitutes the largest superclass of crustaceans, containing approximately four-fifths of all described crustacean species, including crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, barnacles, copepods, amphipods, mantis shrimp and others. The largest branch of multicrustacea is the class Malacostraca.
Allorbimorphus is a genus of Isopoda parasites, in the family Bopyridae, containing the following species that can be found on the coasts of Australia, and Asia:
Aporobopyrus is a genus of Isopoda parasites, in the family Bopyridae, that contains the following 20 species:
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).
Boreomysis sibogae is a species of mysid crustaceans from the subfamily Boreomysinae. It is also a member of the nominotypical subgenus Boreomysis sensu stricto. The species is an epi-bathypelagic mysid, widely distributed in the Indo-Pacific and possibly also in the Atlantic Ocean.
Anacepon is a genus of Isopoda parasites, in the family Bopyridae, containing the following species that can be found on the coast of Indonesia:
