Which mammal, the third largest, is Igano Kabamaru a reference to?
Hippopotamus 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 .
Pika A pika ( ; archaically spelled pica) is a small mammal, with short limbs, very round body, rounded ears, and no external tail. They resemble their close cousin the rabbit, but with shorter ears. They live in mountainous countries in Asia, with two species also in North America. Most pikas prefer rocky slopes. The large-eared pika of the Himalayas and nearby mountains is one of the highest living mammals, found at heights of more than 6000 m . Pikas graze on a range of plants, mostly grasses, flowers and young stems. In the autumn, they pull hay, soft twigs and other stores of food into their burrows to eat during the long, cold winter. The name "pika" is used for any member of the Ochotonidae, a family within the order of lagomorphs, which also includes the Leporidae (rabbits and hares). One genus, Ochotona, is recognised within the family, and it includes 30 species. It is also known as the "whistling hare" due to its high-pitched alarm call when diving into its burrow. In the United States, the pika is colloquially called a "coney", a nonspecific term also used for rabbits, hares, and hyraxes. The name "pika" appears to be derived from the Tungus "piika" and the scientific name "Ochotona" is from the Mongolian word "ogdoi" which means pika.
