Context: Elephants are large mammals of the family Elephantidae and the order Proboscidea. Two species are traditionally recognised, the African elephant ("Loxodonta africana") and the Asian elephant ("Elephas maximus"), although some evidence suggests that African bush elephants and African forest elephants are separate species ("L. africana" and "L. cyclotis" respectively). Elephants are scattered throughout sub-Saharan Africa, South Asia, and Southeast Asia. Elephantidae is the only surviving family of the order Proboscidea; other, now extinct, members of the order include deinotheres, gomphotheres, mammoths, and mastodons. Male African elephants are the largest extant terrestrial animals and can reach a height of and weigh . All elephants have several distinctive features, the most notable of which is a long trunk or proboscis, used for many purposes, particularly breathing, lifting water, and grasping objects. Their incisors grow into tusks, which can serve as weapons and as tools for moving objects and digging. Elephants' large ear flaps help to control their body temperature. Their pillar-like legs can carry their great weight. African elephants have larger ears and concave backs while Asian elephants have smaller ears and convex or level backs., Tropical rainforests occur in areas of tropical rainforest climate in which there is no dry season  all months have an average precipitation of at least 60 mm  and may also be referred to as "lowland equatorial evergreen rainforest". They rarely extend more than 10 degrees north or south of the equator and are a sub-set of the tropical forest biome type that occurs roughly within the 28 degree latitudes (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). Within the World Wildlife Fund's biome classification, tropical rainforests are a type of tropical moist broadleaf forest (or tropical wet forest) that also includes tropical seasonal forests., A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material., A rhinoceros (meaning "nose horn"), often abbreviated to rhino, is one of any five extant species of odd-toed ungulates in the family Rhinocerotidae, as well as any of the numerous extinct species. Two of these extant species are native to Africa and three to Southern Asia., Ethiopia ('), officially known as the Federal Democratic Republic of Ethiopia"' (   , "yetiyoya Fdralaw Dmokirasyaw Rpebilk" ), is a country located in the Horn of Africa. It shares borders with Eritrea to the north and northeast, Djibouti and Somalia to the east, Sudan and South Sudan to the west, and Kenya to the south. With nearly 100 million inhabitants, Ethiopia is the most populous landlocked country in the world, as well as the second-most populous nation on the African continent after Nigeria. It occupies a total area of , and its capital and largest city is Addis Ababa., A Mangrove swamp is a distinct saline woodland or shrubland habitat formed by mangrove trees. They are characterized by depositional coastal environments, where fine sediments (often with high organic content) collect in areas protected from high-energy wave action. The saline conditions tolerated by various mangrove species range from brackish water, through pure seawater (3 to 4%), to water concentrated by evaporation to over twice the salinity of ocean seawater (up to 9%)., Arsinoitherium is an extinct genus of paenungulate mammal belonging to the extinct order Embrithopoda. It is related to elephants, sirenians, hyraxes and the extinct desmostylians. Arsinoitheres were superficially rhinoceros-like herbivores that lived during the late Eocene and the early Oligocene of northern Africa from 36 to 30 million years ago, in areas of tropical rainforest and at the margin of mangrove swamps. A species described in 2004, "A. giganteum", lived in Ethiopia about 27 million years ago., The Paleogene (or ; also spelled Palaeogene or Palæogene; informally Lower Tertiary) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago (Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The Paleogene is most notable for being the time during which mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of the CretaceousPaleogene extinction event that ended the preceding Cretaceous Period. , Desmostylia (from Greek  "desma", "bundle", and  "stylos", "pillar") is an extinct order of aquatic mammals that existed from the late Oligocene (Arikareean) to the late Miocene (Tortonian)., The Eocene Epoch, lasting from , is a major division of the geologic timescale and the second epoch of the Paleogene Period in the Cenozoic Era. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope C in the atmosphere was exceptionally low in comparison with the more common isotope C. The end is set at a major extinction event called the "Grande Coupure" (the "Great Break" in continuity) or the EoceneOligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the epoch are well identified, though their exact dates are slightly uncertain., Sirenia, commonly referred to as sea cows, is an order of fully aquatic, herbivorous mammals that inhabit swamps, rivers, estuaries, marine wetlands, and coastal marine waters. Sirenia comprises the families Dugongidae (the dugong), Trichechidae (manatees), Protosirenidae (Eocene sirenians), and Prorastomidae (terrestrial sirenians). There are currently four extant species of sirenians. Sirenians are classified in the clade Paenungulata, alongside the elephants and the hyraxes, and evolved in the Eocene 50 million years ago. The Dugongidae diverged from the Trichechidae in the late Eocene or early Oligocene., The transition between the end of the Eocene and the beginning of the Oligocene is marked by large-scale extinction and floral and faunal turnover (although minor in comparison to the largest mass extinctions). Most of the affected organisms were marine or aquatic in nature. They included the last of the ancient cetaceans, the Archaeoceti., Embrithopoda ( `` heavy - footed '' ) is an order of extinct mammals known from Asia , Africa and eastern Europe . Most of the embrithopod genera are known exclusively from jaws and teeth dated from the late Paleocene to the late Eocene , but the order is best known from its terminal member , the elephantine Arsinoitherium ., Subject: embrithopoda, Relation: parent_taxon, Options: (A) animal (B) archaeoceti (C) area (D) areas (E) cancer (F) desmostylia (G) dugong (H) elephantidae (I) elephas (J) embrithopoda (K) loxodonta (L) mammal (M) mya (N) paenungulata (O) plant (P) proboscidea (Q) rhinoceros (R) sirenia (S) trichechidae
