Context: Mexico (, modern Nahuatl ), officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost two million square kilometers (over 760,000 sq mi), Mexico is the sixth largest country in the Americas by total area and the 13th largest independent nation in the world. With an estimated population of over 120 million, it is the eleventh most populous country and the most populous Spanish-speaking country in the world while being the second most populous country in Latin America. Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León., Florida (Spanish for "land of flowers") is a state located in the southeastern region of the United States. It is bordered to the west by the Gulf of Mexico, to the north by Alabama and Georgia, to the east by the Atlantic Ocean, and to the south by the Straits of Florida and Cuba. Florida is the 22nd most extensive, the 3rd most populous, and the 8th most densely populated of the U.S. states. Jacksonville is the most populous municipality in the state and is the largest city by area in the contiguous United States. The Miami metropolitan area is Florida's most populous urban area. The city of Tallahassee is the state capital., The ground sloths of the extinct genus Megalocnus ("Great Sloth") were among the largest of the Caribbean ground sloths, with individuals estimated to have weighed up to when alive. Two species are known, "M. rodens" of Cuba, and "M. zile" of Hispaniola. Subfossils of "M. rodens" indicate survival well into the Holocene, prompting speculation that they may have survived in the montane forests of the Cuban highlands until the 15th or 16th century. However, the most recent AMS radiocarbon date reported is 4190 BP, calibrated to c. 4700 BP. This is similar to the most recent date reported for a Hispaniolan sloth, 4391 BP, calibrated to c. 5000 BP, for the small and probably arboreal "Neocnus comes", and some 1200 years after the earliest known date for human occupation of Cuba, 5140 BP, calibrated to c. 5900 BP.
Their relatives include other Caribbean ground sloths, such as "Acratocnus", "Mesocnus", "Miocnus", "Neocnus", "Parocnus", and "Paulocnus"., The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World"., Termites are eusocial insects that are classified at the taxonomic rank of infraorder Isoptera, or as epifamily Termitoidae within the cockroach order Blattodea. Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from close ancestors of cockroaches during the Jurassic or Triassic. However, the first termites possibly emerged during the Permian or even the Carboniferous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called white ants, they are not ants., The northern tamandua ("Tamandua mexicana") is a species of tamandua, a small anteater in the family Myrmecophagidae. They live in tropical and subtropical forests from southern Mexico, through Central America, and to the edge of the northern Andes., Sloths are mammals classified in the families Megalonychidae (two-toed sloths) and Bradypodidae (three-toed sloths), including six extant species. They are named after the capital sin of sloth because they seem slow and lazy at first glance; however, their usual idleness is due to metabolic adaptations for conserving energy. Aside from their surprising speed during emergency flights from predators, other notable traits of sloths include their strong body and their ability to host symbiotic algae on their furs., The southern tamandua ("Tamandua tetradactyla"), also called the collared anteater or lesser anteater, is a species of anteater from South America. It is a solitary animal, found in many habitats from mature to highly disturbed secondary forests and arid savannas. It feeds on ants, termites, and bees. Its very strong fore claws can be used to break insect nests or to defend itself., A sovereign state is, in international law, a nonphysical juridical entity that is represented by one centralised government that has sovereignty over a geographic area. International law defines sovereign states as having a permanent population, defined territory, one government, and the capacity to enter into relations with other sovereign states. It is also normally understood that a sovereign state is neither dependent on nor subjected to any other power or state., Meat is animal flesh that is eaten as food. Humans have hunted and killed animals for meat since prehistoric times. The advent of civilization allowed the domestication of animals such as chickens, sheep, pigs and cattle, and eventually their use in meat production on an industrial scale., Havana (Spanish: "La Habana") is the capital city, largest city, province, major port, and leading commercial centre of Cuba. The city proper has a population of 2.1 million inhabitants, and it spans a total of  making it the largest city by area, the most populous city, and the third largest metropolitan area in the Caribbean region. The city extends mostly westward and southward from the bay, which is entered through a narrow inlet and which divides into three main harbours: Marimelena, Guanabacoa and Atarés. The sluggish Almendares River traverses the city from south to north, entering the Straits of Florida a few miles west of the bay., The Gulf of Mexico is an ocean basin largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Alabama, Florida, Louisiana, Mississippi and Texas border the Gulf on the north, which are often referred to as the "Third Coast" in comparison with the U.S. Atlantic and Pacific coasts, or sometimes the "south coast", in juxtaposition to the Great Lakes region being the "north coast." One of the gulf's seven main areas is the Gulf of Mexico basin., Bees are flying insects closely related to wasps and ants, known for their role in pollination and, in the case of the best-known bee species, the European honey bee, for producing honey and beeswax. Bees are a monophyletic lineage within the superfamily Apoidea, presently considered as a clade Anthophila. There are nearly 20,000 known species of bees in seven to nine recognized families, though many are undescribed and the actual number is probably higher. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants., Santiago de Cuba is the second largest city of Cuba and capital city of Santiago de Cuba Province in the south-eastern area of the island, some south-east of the Cuban capital of Havana., Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones). Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 64,000 species described. Vertebrates include the jawless fish and the jawed vertebrates, which include the cartilaginous fish (sharks and rays) and the bony fish. , The gizzard, also referred to as the ventriculus, gastric mill, and gigerium, is an organ found in the digestive tract of some animals, including archosaurs (dinosaurs including birds, pterosaurs, crocodiles and alligators), earthworms, some gastropods, some fish and some crustaceans. This specialized stomach constructed of thick muscular walls is used for grinding up food, often aided by particles of stone or grit. In certain insects and molluscs, the gizzard features chitinous plates or teeth., Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists., Jamaica is an island country situated in the Caribbean Sea, consisting of the third-largest island of the Greater Antilles. The island, in area, lies about south of Cuba, and west of Hispaniola (the island containing the nation-states of Haiti and the Dominican Republic). Jamaica is the fourth-largest island country in the Caribbean, by area., Isla de la Juventud is the second-largest Cuban island and the seventh-largest island in the West Indies (after Cuba itself, Hispaniola, Jamaica, Puerto Rico, Trinidad, and Andros Island). The island was called the Isle of Pines (Isla de Pinos) until 1978. It has an area and is south of the island of Cuba, across the Gulf of Batabanó. The island lies almost directly south of Havana and Pinar del Río and is a Special Municipality, not part of any province and is therefore administered directly by the central government of Cuba. The island has only one municipality, also named Isla de la Juventud., The Dominican Republic is a sovereign state occupying the eastern two-thirds of the island of Hispaniola, in the Greater Antilles archipelago in the Caribbean region. The western one-third of the island is occupied by the nation of Haiti, making Hispaniola one of two Caribbean islands, along with Saint Martin, that are shared by two countries. The Dominican Republic is the second-largest Caribbean nation by area (after Cuba) at , and 3rd by population with 10.08 million people, of which approximately three million live in the metropolitan area of Santo Domingo, the capital city., Cuba, officially the Republic of Cuba, is a country comprising the island of Cuba as well as Isla de la Juventud and several minor archipelagos. Cuba is located in the northern Caribbean where the Caribbean Sea, the Gulf of Mexico, and the Atlantic Ocean meet. It is south of both the U.S. state of Florida and the Bahamas, west of Haiti, and north of Jamaica. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. Cuba is the largest island in the Caribbean, with an area of , and the second-most populous after Hispaniola, with over 11 million inhabitants., Mammals are any vertebrates within the class Mammalia (from Latin "mamma" "breast"), a clade of endothermic amniotes distinguished from reptiles and birds by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands. The sister group of mammals may be the extinct "Haldanodon." The mammals represent the only living Synapsida, which together with the Sauropsida form the Amniota clade. The mammals consist of the Yinotheria including monotrema and the Theriiformes including the theria., Hispaniola (Spanish: "La Española"; Latin: "Hispaniola"; Taíno: "Haiti") is the 22nd-largest island in the world, located in the Caribbean island group, the Greater Antilles. It is the second largest island in the Caribbean after Cuba, and the tenth most populous island in the world., Neocnus is an extinct genus of ground sloth , whose species ranged across Cuba and Hispaniola ( Haiti and Dominican Republic ) . Neocnus would have resembled a typical megalonychid ground sloth , though much smaller , with a longer tail and a broad trunk , as well as lissome limbs and long claws . This sloth was known for having caudal vertebrae that were broad , a trait shared with other ground sloths , indicating that this animal , like the tamandua of today , likely used its tail to stand upright . The caniniform teeth of the Neocnus were large and triangular , and its skull was deep and had a large , sagittal crest which , when used with the deep mandible likely allowed strong exertion by the masticatory muscles . The fossils of this sloth were found in Haitian cave deposits . They have been dated to as recently as 4391 BP , calibrated to c. 5000 BP . It is theorized that this sloth , in common with other Antillean sloths , was killed off by humans seeking its pelt and meat . Currently , this species of sloth is being studied by evolutionary historians . Neocnus is suspected of having been semi-arboreal ., A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus., In botany, a fruit is the seed-bearing structure in flowering plants (also known as angiosperms) formed from the ovary after flowering., Anteater is a common name for the four extant mammal species of the suborder Vermilingua (meaning "worm tongue") commonly known for eating ants and termites. The individual species have other names in English and other languages. Together with the sloths, they are within the order Pilosa. The name "anteater" is also colloquially applied to the unrelated aardvark, numbat, echidnas, pangolins and some members of the Oecobiidae., Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus., Grasslands are areas where the vegetation is dominated by grasses (Poaceae), however sedge (Cyperaceae) and rush (Juncaceae) families can also be found. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (ecosystem), which is one of eight terrestrial ecozones of the Earth's surface., Ground sloths are a diverse group of extinct sloths, in the mammalian superorder Xenarthra. The term "ground sloth" is used as a reference for all extinct sloths because of the large size of the earliest forms discovered, as opposed to the extant "tree sloths." However, this is a historical convention and should not imply that all extinct sloths were strictly terrestrial in nature. Their most recent survivors lived in the Antilles, where it has been proposed they may have survived until 1550 BCE; however, radiocarbon dating suggests an age of between 2819 and 2660 BCE for the last known occurrence of "Megalocnus" in Cuba. Ground sloths had been extinct on the mainland of North and South America for 10,000 years or more. Their later survival in the Caribbean correlates with the later colonization of this area by humans. Some insular sloth populations persisted 5,0006,000 years longer than their continental mainland relatives, in congruence with the global pattern of late Quaternary large vertebrate extinction due to human dispersal., In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs., Santo Domingo (meaning "Saint Dominic"), officially Santo Domingo de Guzmán, is the capital and largest city in the Dominican Republic and the largest metropolitan area in the Caribbean by population. In 2010, its population was counted as 965,040, rising to 2,908,607 when its surrounding metropolitan area was included. The city is coterminous with the boundaries of the Distrito Nacional ("D.N.", "National District"), itself bordered on three sides by Santo Domingo Province., A prehensile tail is the tail of an animal that has adapted to be able to grasp or hold objects. Fully prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees. If the tail cannot be used for this it is considered only partially prehensile - such tails are often used to anchor an animal's body to dangle from a branch, or as an aid for climbing. The term "prehensile" means "able to grasp" (from the Latin "prehendere", to take hold of, to grasp)., Tamandua is a genus of anteaters with two species: the southern tamandua ("T. tetradactyla") and the northern tamandua ("T. mexicana"). They live in forests and grasslands, are semiarboreal, and possess partially prehensile tails. They mainly eat ants and termites, but they occasionally eat bees, beetles, and insect larvae. In captivity, they will eat fruits and meat. They have no teeth and depend on their powerful gizzards to break down their food., The superorder Xenarthra is a group of placental mammals, extant today only in the Americas and represented by anteaters, tree sloths, and armadillos. The origins of the order can be traced as far back as the Paleocene, as early as 59 million years ago in South America. Xenarthrans developed and diversified extensively in South America during its long period of isolation in the early to mid Cenozoic Era. They had invaded the Antilles by the early Miocene and, starting about 9 Mya, spread to Central and North America as part of the Great American Interchange. Nearly all of the formerly abundant megafaunal xenarthrans, such as ground sloths, glyptodonts, and pampatheres, became extinct at the end of the Pleistocene., Subject: neocnus, Relation: parent_taxon, Options: (A) alabama (B) amniota (C) angiosperms (D) animal (E) anteater (F) anthophila (G) area (H) areas (I) blattodea (J) chordata (K) homo (L) honey bee (M) insects (N) juncaceae (O) la (P) mammal (Q) megalonychidae (R) mya (S) myrmecophagidae (T) pilosa (U) poaceae (V) sauropsida (W) sloth (X) tamandua (Y) theria (Z) vertebrata ([) xenarthra
