Remipedia is a class of blind crustaceans found in coastal aquifers which contain saline groundwater, with populations identified in almost every ocean basin so far explored, including in Australia, the Caribbean Sea, and the Atlantic Ocean. The first described remipede was the fossil Tesnusocaris goldichi. Since 1979, at least seventeen living species have been identified in subtropical regions around the world.
Speleonectidae is a family of remipedes in the order Nectiopoda. There are at least two genera and about seven described species in Speleonectidae.
Anaspididae is a family of freshwater crustacean that is endemic to Tasmania, Australia. The family contains 3 genera and 5 species. This group of crustaceans are considered living fossils. They are commonly and collectively known as the Tasmanian anaspid crustaceans. Anaspidids have stalked eyes, long antennae and antennules, and a slender body with no carapace. The two species of Allanaspides and the single species of Paranaspides are all listed as vulnerable on the IUCN Red List.
Arubolana aruboides is a species of crustacean in the family Cirolanidae. It is endemic to Bermuda.
Bermudamysis speluncola is a species of crustacean in the family Mysidae, endemic to Bermuda, and the only species in the genus Bermudamysis.
Bermudagidiella bermudiensis is a species of crustacean in the family Bogidiellidae. It is the only species in the genus Bermudagidiella, and is endemic to Bermuda.
Cocoharpinia iliffei is a species of crustacean in the family Phoxocephalidae. It is endemic to Bermuda.
Curassanthura bermudensis is a species of isopod crustacean in the family Leptanthuridae, endemic to Bermuda. It was described in 1985 by Johann Wägele and Angelika Brandt on the basis of a single immature specimen. This holotype specimen, which is 3 millimetres (0.12 in) long, was collected from Church Cave in Hamilton Parish, Bermuda, and is now stored at the Zoological Museum Amsterdam.
Erebonectes is a genus of crustacean in family Epacteriscidae, containing two troglobitic species. E. nasioticus was discovered in Bermuda and described in 1985; it is listed as critically endangered on the IUCN Red List. E. macrochaetus was found on Middle Caicos and described in 1994.
Idunella sketi is a species of crustacean in family Liljeborgiidae. It is endemic to Bermuda.
Ingolfiella longipes is a species of amphipod crustacean in the family Ingolfiellidae. It is known from a single specimen held at the Naturalis Biodiversity Center. It was collected from Walsingham Sink Cave, an anchialine cave in Hamilton Parish, Bermuda, and is thus considered to be critically endangered.
Platyops sterreri is a species of crustacean in the family Mysidae, endemic to Bermuda, the only species in the genus Platyops.
Pseudoniphargus grandimanus is a species of crustacean in family Hadziidae. It is endemic to Bermuda.
Parhippolyte sterreri is a species of marine decapod crustacean in the family Barbouriidae, formerly placed in the genus Somersiella. It is found in marine caves around the Bahamas, Cuba and Mexico and inland anchialine caves in Bermuda.
Spelaeoecia bermudensis is a species of ostracod in the family Deeveyidae.
Speleoithona bermudensis is a species of crustacean in the family Speleoithonidae. It is endemic to Bermuda. Its natural habitat is karsts.
Speleophria scottodicarloi is a species of crustacean in the family Speleophriidae. It is endemic to Chalk Cave, a collapsed cave in Smith's Parish, Bermuda, and it listed as critically endangered on the IUCN Red List. The pool it inhabits also contains Barbouria cubensis, Somersiella sterreri and Paracyclopia naessi.
Typhlatya is a genus of shrimp in the family Atyidae. These are small, stygobitic shrimp found in the West Mediterranean region, Caribbean region, Ascension Island and the Galápagos, although the individual species often have very small ranges. Species in this genus are found in salt, brackish and fresh waters, mostly in anchialine habitats and none in the open sea.
Cypridinidae is a family of ostracods, containing the following genera:
Xibalbanus tulumensis is a venomous, hermaphroditic crustacean found in anchialine caves on the Yucatán Peninsula in the Caribbean Sea. This blind remipede liquefies the body contents of other crustaceans with a venom similar to that of rattlesnakes, and which includes digestive enzymes and a paralysing toxin.
