Branchiopoda is a class of crustaceans. It comprises fairy shrimp, clam shrimp, Diplostraca, Notostraca and the Devonian Lepidocaris. They are mostly small, freshwater animals that feed on plankton and detritus.
Rheidae is a family of flightless ratite birds which first appeared in the Paleocene. It is today represented by the sole living genus Rhea, but also contains several extinct genera.
Guaiacum, sometimes spelled Guajacum, is a genus of flowering plants in the caltrop family Zygophyllaceae. It contains five species of slow-growing shrubs and trees, reaching a height of approximately 20 m (66 ft) but usually less than half of that. All are native to subtropical and tropical regions of the Americas and are commonly known as lignum-vitae, guayacán (Spanish), or gaïac (French). The genus name originated in Taíno, the language spoken by the native Taínos of the Bahamas; it was adopted into English in 1533, the first word in that language of American origin.
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.
Notodiaphana fragilis is a species of marine snail, gastropod mollusk in the clade Architectibranchia.
The Cephalocarida are a class in the subphylum Crustacea comprising only 12 benthic species. They were discovered in 1955 by Howard L. Sanders, and are commonly referred to as horseshoe shrimp. They have been grouped together with the Remipedia in the Xenocarida. Although a second family, Lightiellidae, is sometimes used, all cephalocaridans are generally considered to belong in just one family: Hutchinsoniellidae. Though no fossil record of cephalocaridans has been found, most specialists believe them to be primitive among crustaceans.
Pancrustacea is the clade that comprises all crustaceans and hexapods. This grouping is contrary to the Atelocerata hypothesis, in which Myriapoda and Hexapoda are sister taxa, and Crustacea are only more distantly related. As of 2010, the Pancrustacea taxon is considered well accepted, with most studies recovering Hexapoda within Crustacea. The clade has also been called Tetraconata, referring to having four cone cells in the ommatidia. This name is preferred by some scientists as a means of avoiding confusion with the use of "pan-" to indicate a clade that includes a crown group and all of its stem group representatives.
Speleonectidae is a family of remipedes in the order Nectiopoda. There are at least two genera and about seven described species in Speleonectidae.
Godzilliidae is a family of remipedes in the order Nectiopoda. There are at least two genera and four described species in Godzilliidae.
Phreatogammarus is a genus of amphipod crustaceans that are endemic to New Zealand. It is the only genus in the family Phreatogammaridae, and contains four species, three of which were described by Charles Chilton.
Samoana is a genus of tropical, air-breathing, land snails, terrestrial pulmonate gastropod mollusks in the family Partulidae.
Chthamalus is a genus of barnacles that is found along almost all non-boreal coasts of the northern hemisphere, as well as many regions in the southern hemisphere. These small barnacles have been studied in part because of the taxonomic confusion over a group of species that, by and large, are morphologically and ecologically quite similar. In recent years, molecular techniques have identified a number of cryptic species that have been subsequently confirmed by taxonomists using morphological measurements. Most recently the genus has been shown to be paraphyletic, with the genus Microeuraphia nested within Chthamalus.
Morlockia atlantida is a species of eyeless crustacean in the order Nectiopoda. It was discovered in August 2009 in the Túnel de la Atlántida, the world's longest submarine lava tube on Lanzarote in the Canary Islands off the west coast of North Africa. Originally named Speleonectes atlantida, it was transferred to genus Morlockia in 2012. Like other remipedes, the species is equipped with venomous fangs.
Chickcharnea is a monotypic genus in the family Buccinidae, the true whelks, containing one species of sea snail, a marine gastropod mollusk, Chickcharnea fragilis.
Crustaceans may pass through a number of larval and immature stages between hatching from their eggs and reaching their adult form. Each of the stages is separated by a moult, in which the hard exoskeleton is shed to allow the animal to grow. The larvae of crustaceans often bear little resemblance to the adult, and there are still cases where it is not known what larvae will grow into what adults. This is especially true of crustaceans which live as benthic adults, more-so than where the larvae are planktonic, and thereby easily caught.
Godzilliognomus schrami is a species of Remipedia discovered in 2007, representing one of five extant species of the family Godzilliidae. It generally reaches about 7 millimetres (0.28 in) in length and inhabits a single anchialine cave on Eleuthera Island. The specific epithet commemorates Frederick Schram.
Macromaxillocaris bahamaensis is a species of stenopodidean shrimp, the only species in the family Macromaxillocarididae. It is a troglobite, known only from an anchialine pool in a cave in the Bahamas. It differs from other stenopodideans by the enlargement of its third maxilliped.
Crustaceans form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans are more closely related to insects and the other hexapods than they are to certain other crustaceans.
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.
Lucayan National Park is a national park in Grand Bahama, the Bahamas. The park was established in 1982 and has a land area of 40 acres (16 ha), and 1,937 acres (7.84 km2) in total. The park contains an underwater cave system with 6 mi (9.7 km) of charted tunnels.
