Wildlife of Sierra Leone
Sierra Leone has 15 identified species of primates that include bushbaby, monkeys and a great ape, the common chimpanzee which is Sierra Leone's largest primate. Chimpanzees are found across the country with the 2010 chimpanzee census estimated a wild population in excess of 5500 more than double the number previously thought to live in the country. This is the second largest population of the endangered subspecies of western chimpanzee, after Guinea,
with the largest density in the Loma area, 2.69 individuals per km2, and the Outamba, with 1.21 individuals per km2.
List of mammals of the Philippines
Elephants comprise three living species and are the largest living land animals. One species, the Asian elephant - unknown subspecies like those on Sabah, once lived in both the Sultanate of Sulu and Maguindanao, though became extinct on those areas because of hunting and/or were transported back to Sabah for unknown reasons.Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered. One species occur in the Philippines. One fossil species has been discovered in the Philippines in 2011. The fossil hasn't yet been extracted from the rocks in fear of destroying the natural heritage caves of Palawan which are protected by Philippine Law. Future technology in fossil extraction is the only way to get and identify the fossil remain in peace according to the scientists who found the remains.The treeshrews are small mammals native to the tropical forests of Southeast Asia. Although called treeshrews, they are not true shrews and are not all arboreal. Three species occur in the Philippines, though the Calamian treeshrew is not yet fully considered by the IUCN as a full separate species because assessment is not yet done at present to confirm the movement as of 2013.The two species of colugos make up the order Dermoptera. They are arboreal gliding mammals found in Southeast Asia. Only one species occurs in the Philippines and is endemic to the Mindanao Faunal Region.The order Primates contains humans and their closest relatives: lemurs, lorisoids, monkeys, and apes. Three endemic species occurs in the Philippines.Rodents make up the largest order of mammals, with over 40 percent of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing. Most rodents are small though the capybara can weigh up to 45 kg (100 lb). As of 2014, 86 native species occur in the Philippines, most endemic to the archipelago. One discovered fossil species has been extinct since the Pleistocene Epoch. The number of species is speculated to rise more because of the high endemic concentration on the islands, which were mostly isolated from Mainland Asia in prehistoric times. There are also three introduced species of rodents in the archipelago; the most common introduced rodents: the house mouse, black rat, and the brown rat, which are considered worldwide pests.The order Erinaceomorpha contains a single family, Erinaceidae, which comprise the hedgehogs and gymnures. The hedgehogs are easily recognised by their spines while gymnures look more like large rats. Two species occurs in the Philippines as of 2013, though speculation persists that perhaps there will be future moonrat species on Leyte, Samar, Basilan, or even Bohol because they were also once part of the Mindanao Faunal Region like Mindanao and Dinagat. The "shrew-forms" are insectivorous mammals. The shrews and solenodons closely resemble mice while the moles are stout-bodied burrowers. Twelve species occur in the Philippines, most of which are endemic.The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals in the world naturally capable of flight. Bat species account for about 20% of all mammals. Ninety species occur in the Philippines, though the exact number of species is truly unknown because of the uneven distribution of bat species in Southeast Asia and Australasia. More additional field survey is needed in all of the 7,107 islands of the country archipelago to determine the exact species that occur in the country, and to know the exact number of species that actually live in the archipelago.The order Philodota comprises the eight species of pangolin. Pangolins are anteaters and have the powerful claws, elongated snout and long tongue is seen in the other unrelated anteater species. One species occurs in the Philippines, the Philippine pangolin which was elevated to full species status from the Sunda pangolin.The order Cetacea includes whales, dolphins and porpoises. They are the mammals most fully adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion underwater. The number of Cetacea species that occur in the Philippines is critically unsure. More research and field work is needed to confirm the exact number. 
There are over 260 species of carnivorans, the majority of which feed primarily on meat. They have a characteristic skull shape and dentition. Seven native species occurs in the Philippines, the second smallest number of carnivore species in any of the Asia-Pacific region countries, next to East Timor. And the smallest number in Southeast Asia compared to land size. One species or subspecies has been introduced: the domestic cat, although its origin is uncertain whether it originated from the leopard cat (though thought by some as introduced in the Visayas from Palawan) in the country or migrated with the Malays, or from Spain and America, or more than two of the former theories. Two subspecies are introduced to the country, the dingo which became extinct 15,000 years ago (dingo migration theory), and the aspin ( the term for the domestic dog in the Philippines) which probably evolved from the dingo.The odd-toed ungulates are browsing and grazing mammals. They are usually large to very large and have relatively simple stomachs and a large middle toe. One species was introduced from Malaysia (probably from Saudi Arabia) and was bred with those that were imported from Spain when the Spaniards built the Spanish East Indies in the Philippines in the 16th century.The even-toed ungulates are ungulates whose weight is borne about equally by the third and fourth toes, rather than mostly or entirely by the third as in perissodactyls. There are about 220 artiodactyl species, including many that are of great economic importance to humans. 10 native species occur in the Philippines, including the "Sus" populations in Tawi-tawi Province which are the only Bornean bearded pigs in the country. 5 introduced species occurs in the country: 1.) The carabao, which originated from the water buffalo in Mainland Asia, 2.) The domesticated goat - Philippine breed, 3.) The domesticated pig, though some domesticated pigs in the country originated from native "Sus" species like those of Banaue, 4.) The domestic cattle, which hybridized from the banteng, and Mexican domestic cattle, forming the breed, Philippine cattle which is further divided into 4 varieties, 5.) The Jolo sika deer which was anciently introduced to Sulu (unknown date, unknown subspecies origin), though it might be already extinct.
