Context_2 : Samuel Husbands Beckles (12 April 1814 in Barbados – 4 September 1890 in Hastings) was a Bajan/English 19th-century lawyer, turned dinosaur hunter, who collected remains in Sussex and the Isle of Wight. In 1854 he described bird-like trackways that he thought could have been made by dinosaurs, which he later identified as probably those of "Iguanodon" in 1862. In 1857, following the discovery of a mammal jaw at Durlston Bay, he directed a major excavation that became known as 'Beckles' Pit', removing five metres of overburden over a 600 square metre area, one of the largest ever scientific excavations. The collection of mammal fossils that resulted is now mainly held at the Natural History Museum. He discovered the small herbivorous dinosaur "Echinodon". The only known species "Echinodon becklesii", the mammal "Plagiaulax becklesii" and the dinosaur "Becklespinax" were named in his honour. Context_3 : The common hippopotamus ("Hippopotamus amphibius"), or hippo, is a large, mostly herbivorous and aggressive mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus ("Choeropsis liberiensis" or "Hexaprotodon liberiensis"). The name comes from the ancient Greek for "river horse" (ἱπποπόταμος ). After the elephant and rhinoceros, the common hippopotamus is the third-largest type of land mammal and the heaviest extant artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the Hippopotamidae are cetaceans (whales, dolphins, porpoises, etc.) from which they diverged about . The common ancestor of whales and hippos split from other even-toed ungulates around . The earliest known hippopotamus fossils, belonging to the genus "Kenyapotamus" in Africa, date to around . Context_4 : Handbook of the Mammals of the World (HMW) is a book series from the publisher Lynx Edicions. The nine volumes will be published from 2009. Each mammal family is assessed in a full text introduction with photographs and each species has a text account with a distribution map and illustrations on a plate. This is the second major project by Lynx Edicions since the release of the "Handbook of the Birds of the World" in 1992. The chief editors are Russell Mittermeier and Don E. Wilson in association with Conservation International, the Texas A&M University and the IUCN. Don E. Wilson is also editor of the reference work "Mammal Species of the World". Context_5 : This is a list of the mammal species recorded in Pakistan. There are 173 mammal species in Pakistan, of which 12 are critically endangered, 11 are endangered, 14 are vulnerable, and 10 are near-threatened. The largest mammal in Pakistan is the Asiatic brown bear. "Capra falconeri" is the national animal of Pakistan. Context_6 : Caen ( ; ] ; Norman: "Kaem") is a commune in northwestern France. It is the prefecture of the Calvados department. The city proper has 108,365 inhabitants (as of 2012 ), while its urban area has 420,000, making Caen the largest city in former Lower Normandy. It is also the third largest municipality in all of Normandy after Le Havre and Rouen and the third largest city proper in Normandy, after Rouen and Le Havre. The metropolitan area of Caen, in turn, is the second largest in Normandy after that of Rouen, the 21st largest in France. Context_7 : In mammalian oral anatomy, the canine teeth, also called cuspids, dog teeth, fangs, or (in the case of those of the upper jaw) eye teeth, are relatively long, pointed teeth. However, they can appear more flattened, causing them to resemble incisors and leading them to be called "incisiform." They developed and are used primarily for firmly holding food in order to tear it apart, and occasionally as weapons. They are often the largest teeth in a mammal's mouth. Most species that develop them normally have four per mammal, two in the upper jaw and two in the lower, separated within each jaw by its incisors; humans and dogs are examples. In most species, canines are the anterior-most teeth in the maxillary bone. Context_8 : Dolfinarium Harderwijk, better known as the Dolfinarium, is a marine mammal park in Harderwijk, the Netherlands. It is the largest marine mammal park in Europe. Visitor numbers were steady from 2005 to 2011, numbering between 700,000 and 800,000, with only the opening of new attractions responsible for a surge in numbers. In 2012 the Dolfinarium made €12 million in sales, which was around €2,4 million lower than the year before. This was mainly due to a decline in visitor numbers because of orca Morgan leaving the park, and the park temporarily closing down due to the start of construction at the end of the year. Context_9 : Igano Kabamaru (伊賀野カバ丸 , Igano Kabamaru , lit. "Hippo Mouth of Iga") is a Japanese manga created by Yu Azuki.

The plot deals mainly with Kabamaru adjusting to an urban lifestyle after spending a childhood in the mountains and how he finds himself caught up in the rivalry between two private schools. Context_10 : Mammal Species of the World: A Taxonomic and Geographic Reference is a standard reference work in zoology giving descriptions and bibliographic data for the known species of mammals. It is now in its third edition that was edited by Don E. Wilson and DeeAnn M. Reeder. An updated "Third Edition of Mammal Species of the World" was published late in 2005. fact_1 : Igano Kabamaru (伊賀野カバ丸 , Igano Kabamaru , lit. " fact_2 : The common hippopotamus ("Hippopotamus amphibius"), or hippo, is a large, mostly herbivorous and aggressive mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus ("Choeropsis liberiensis" or "Hexaprotodon liberiensis"). fact_3 :  After the elephant and rhinoceros, the common hippopotamus is the third-largest type of land mammal and the heaviest extant artiodactyl. Answer: Hippopotamus
Output: Which mammal, the third largest, is Igano Kabamaru a reference to?
