Macromaxillocaris
''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. Description The holotype of ''M. bahamaensis'' has a total length (TL) of (carapace length, CL, ); the paratype is smaller at TL , CL . In common with other troglobitic species, the body lacks pigments, and the eyes are vestigial. Like other stenopodideans, ''Macromaxillocaris'' has chelae (claws) on the first three pairs of pereiopods (walking legs); it differs from them by the size of the third maxilliped, which is greatly enlarged in ''Macromaxillocaris'', and is the strongest of all the animal's appendages. Distribution and habitat ''Macromaxillocaris bahamaensis'' is the first species discovered among the Stenopodidea to be adapted to a troglobitic lifestyle. It was found in an anchialine ...

Troglobite
A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves. These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors ( subtroglophiles and trogloxenes). Land-dwelling troglobites may be referred to as troglofauna, while aquatic species may be called stygofauna, although for these animals the term ''stygobite'' is preferable. Troglobites typically have evolutionary adaptations to cave life. Examples of such adaptations include slow metabolism, reduced energy consumption, better food usage efficiency, decrease or loss of eyesight (anophthalmia), and depigmentation (absence of pigment in the integument). Conversely, as opposed to lost or reduced functions, many species have evolved elongated antenna and locomotory appendages, in order to better move around and respond to environmental s ...

Stenopodidea
The Stenopodidea or boxer shrimps are a small group of decapod crustaceans. Often confused with Caridea shrimp or Dendrobranchiata prawns, they are neither, belonging to their own group. Anatomy They can be differentiated from the Dendrobranchiata prawns by their lack of branching gills, and by the fact that they brood their eggs instead of directly releasing them into the water. They differ from the Caridea shrimp by their greatly enlarged third pair of legs. Taxonomy Stenopodidea belongs to the order Decapoda, and is most closely related to the Caridea and Procarididea infraorders of shrimp. The cladogram below shows Stenopodidea's relationships to other relatives within Decapoda, from analysis by Wolfe ''et al.'', 2019. There are 71 extant species currently recognized within Stenopodidea, divided into 12 genera. Three fossil species are also recognized, each belonging to a separate genus. The earliest fossil assigned to the Stenopodidea is '' Devonostenopus pennsylvan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Zoologische Mededelingen
''Zoologische Mededelingen'' was a peer-reviewed open access scientific journal publishing papers and monographs on animal systematics. The publisher was the National Museum of Natural History Naturalis in the Netherlands. The first issue appeared in 1915, as the official journal of Naturalis' predecessor, the Rijks Museum van Natuurlijke Historie. Earlier, the museum published ''Muséum d'Histoire Naturelle des Pays-Bas'' (volumes I-XIV, 1862-1908) and ''Notes from the Leyden Museum'' (volumes I-XXXVI, 1879-1914), which mainly covered the fauna of the Netherlands and the former Dutch colonies. ''Zoologische Mededelingen'' was indexed in ''The Zoological Record'' and ''BIOSIS''. A complete backlist of published volumes is presented on the institutional repository of Naturalis. The last article was published in 2014 and the journal was merged into the ''European Journal of Taxonomy The ''European Journal of Taxonomy'' is a peer-reviewed open access scientific journal for descrip ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
