Most recently described class of crustaceans

In 1979, while diving in Lucayan Cavern, a water-filled cave beneath the island of Grand Bahama, American biologist Dr Jill Yager encountered some tiny worm-like crustaceans that proved to be not only a new species, dubbed Speleonectes lucayensis, but also one so different from all others that in 1981 an entirely new taxonomic class of crustaceans - Remipedia - was created in order to accommodate it. Several additional, related species have since been discovered, all of which are blind and characterised by their oar-like limbs, hence these crustaceans are termed remipedes ('oar-footed').
