1. Florida panther – The Florida panther is an endangered subspecies of cougar that lives in forests and swamps of southern Florida in the United States. Its current taxonomic status is unresolved, but recent genetic research alone does not alter the legal conservation status, Florida panthers are usually found in pinelands, hardwood hammocks, and mix swamp forests. Males can weigh up to 160 pounds and live within a range that includes the Big Cypress National Preserve, Everglades National Park, and this population, the only unequivocal cougar representative in the eastern United States, currently occupies 5% of its historic range. In the 1970s, there were an estimated 20 Florida panthers in the wild, in 2013, it was reported that there are only 160 Florida panthers in the wild. In 1982, the Florida panther was chosen as the Florida state animal, Florida panthers are spotted at birth and typically have blue eyes. As the panther grows the spots fade and the coat becomes completely tan while the eyes typically take on a yellow hue, the panthers underbelly is a creamy white, and it has black tips on the tail and ears. Florida panthers lack the ability to roar, and instead make distinct sounds that include whistles, chirps, growls, hisses, Florida panthers are mid-sized for the species, being smaller than cougars from Northern and Southern climes but larger than cougars from the neotropics. Adult female Florida panthers weigh 29–45.5 kg whereas the males weigh 45. 5–72 kg. Total length is from 1.8 to 2.2 m, male panthers, on average, are 9. 4% longer and 33. 2% heavier than females. This is because males grow at a faster rate than females, the Florida panther has long been considered a unique subspecies of cougar, under the trinomial Puma concolor coryi, one of thirty-two subspecies once recognized. Following the research, the canonical Mammal Species of the World ceased to recognize the Florida panther as a subspecies, collapsing it. Despite these findings it is listed as subspecies Puma concolor coryi in research works. And the proposed change in taxonomy is not resolved at this time, the hunting season of the panther is greatly affected by the behavior of their prey, especially the deer. Deer are nocturnal in nature which makes hunting especially for type of prey more of a success for panthers since they are nocturnal hunters. When hunting, panthers shift their hunting environment based on where the base is. The female panther in particular is especially dependent on nutrition because their reproductive rates, home range size, Panther kittens are born in dens created by their mothers, often in dense scrub. The dens are chosen based on a variety of factors, including prey availability, kittens will spend the first 6–8 weeks of life in those dens, dependent on their mother. Once they are old enough to leave the den, they hunt in the company of their mother
2. L'Hoest's monkey – LHoests monkey, or mountain monkey, is a guenon found in the upper eastern Congo basin. They mostly live in mountainous forest areas in small, female-dominated groups and they have a dark coat and can be distinguished by a characteristic white beard. LHoests monkey is currently classified as a member of the genus Cercopithecus, formerly, LHoests monkey included the taxon preussi from the Gulf of Guinea region as a subspecies, but it is now considered a separate species, Preusss monkey. Together with the monkey, these make up the C. lhoesti group. Molecular studies published by Anthony Tosi in 2003 have raised doubts about the current classification of LHoests monkey as a member of the genus Cercopithecus. The studies indicated that LHoests monkey is more related to the vervet monkeys of the genus Chlorocebus. It is not yet clear how the situation will be resolved. Proposed solutions include moving both LHoests monkey and the monkey into the genus Chlorocebus or moving just LHoests monkey into a new genus, Allochrocebus. C. lhoesti has a short, dark coat, with a chestnut color across the back. Its cheeks are light gray with a pale moustache and it has a characteristic and prominent white bib, In body length it is 12.5 to 27 inches, with a 19-to-39-inch tail. The male weighs about 6 kilograms, while the female weighs 3.5 kilograms. Its tail is long and hook-shaped at the end and they are born fully coated and with their eyes open. LHoests monkey occurs in northeastern Democratic Republic of the Congo, Rwanda, Burundi and it is a forest monkey, which is typical of the moist and high primary forests. It will occupy a range of different kinds of forested areas, including gallery forest, mature lowland forests, wooded savanna at mountain slopes. However, it also live on cultivated lands. In lowland forests it shows a preference toward areas where the forest is regenerating, while in areas it will frequent the mature, tangled. One study found this population only above 900 metres but another found it as low as 610 metres, another mostly observed it from 1,500 to 2,500 metres. C. lhoesti lives in small groups dominated by females and have only a single male
3. Luzon montane forest mouse – The Luzon montane forest mouse is a species of rodent in the family Muridae, from the genus Apomys. It occurs only in the Philippines, where it has found on the large northern island Luzon. It is most closely related to the large Mindoro forest mouse, there may be another related species in the Sierra Madre, but this species is yet undescribed. The Luzon montane forest mouse is a large, ground-dwelling rat with a tail that is quite short for its genus. The Luzon montane forest mouse was the first species of Apomys ever to be discovered, in 1895, an expedition was organised which brought to Europe the first specimens of several genera, including Carpomys, Rhynchomys and Crunomys. Meyer described th animal as Mus datae in 1899, after its type locality – Mount Data, for a long time, little was known about Mus datae, until 1913, when American biologist Ned Hollister described eight rats from Luzon under the name Epimys datae. These were in fact examples of the Himalayan field rat, but they were identified as such in 1977. Meanwhile, in Britain, John Ellerman had finally placed Mus datae with its relatives in Apomys, eleven years later, in 1952, American zoologist Colin Campbell Sanborn announced that he had captured 54 specimens of A. datae on Mount Data. In a 1982 article, Musser defined the genus Apomys and gave the first modern description of A. datae, datae, while the other animals to have been identified as A. major were discovered to be examples of A. abrae. Since that time, Apomys major has been considered a synonym of A. datae. Musser identified A. datae as the member of the Apomys datae group within the genus. In 1993 and 1994, the species was observed in the Sierra Madre, at an altitude between 760 and 1,650 m, but this concerns a population of a separate. A second species within the A. datae group was described by Luis Ruedas, in 1995, in the 21st century, the knowledge about A. datae was expanded with data from genetic research. In 2002, the karyotype was revealed, and in 2003, most recently, the animal has been found on several new locations in North Luzon. Animals in this division share several morphological and genetic features, Apomys itself was divided into two groups, in the aforementioned article by Musser from 1982, the datae group, containing only A. datae, and the abrae-hylocetes group, containing all other species. Animals in these two groups differ in the way in which the head is supplied with blood from arteries, since the publication of Mussers article, another species has been described that falls into the datae group, A. gracilirostris. This relationship is supported by other similarities, both species are relatively large for the genus and have a relatively long snout. In 2003, a study was published which compared DNA sequences from the cytochrome b gene of thirteen species of Apomys
4. Red-crested tree-rat – Santamartamys is a monotypic genus of rodent in family Echimyidae, containing only the red-crested tree rat. It is nocturnal and is believed to feed on plant matter, IUCN list the species as critically endangered, it is affected by feral cats, climate change, and the clearing of forest in its potential range in coastal Colombia. Found at altitudes of 700 to 2,000 metres, the species is endemic to Colombia in an area with high levels of biodiversity. The species was identified as Isothrix rufodorsalis in 1899, re-classified as Diplomys rufodorsalis in 1935. On 24 December 1898, Herbert Huntingdon Smith identified the first specimen of Santamartamys in Ocana, Santa Marta, Magdalena and it is assumed that the specimen was obtained through a gift or was purchased. It was recorded as a Santamartamys specimen in 1913 at the American Museum of Natural History in New York, despite several organised searches, no other specimens were discovered. However, on 4 May 2011, two volunteers from Fundación ProAves identified a young specimen in nature reserve El Dorado, Sierra Nevada de Santa Marta. At 1,958 m above sea level, the animal was identified by five people at 11°06′02. 93″N 74°04′19. 36″W, Santamartamys specimens measure between 51 and 122 cm from head to the tip of their tail, with their tails measuring between 18 and 28 cm. The species can weigh up to 500 g, and has a woolly, soft, the hair on the dorsal region is of intense red colouring, and a large portion of the tail hair is black, but the last two-fifths of the tail are white. Its ears are small and light brown, and feature tufts of hair on the inner surface. Between the eye and the ear, there is a tuft of black hairs. The thin whiskers can reach up to 13 cm long, and has a strip of red fur around its neck, the upper surfaces of the front and rear legs are covered in a pale gray coat, and the hind legs are very short and wide. The feet lack small tubercles and the thumb is covered by a nail and its skull is short and wide, and it has a heavy, large, and uncurved zygomatic bone. The supraorbital ridge of the skull is large, and the region is very broad with nearly parallel sides. The facial portion of the skull is short, and the distance between the incisors and the molars is slightly less than the length of the coronary surface of its upper row of teeth. Santamartamys has large eyes, which is consistent with its nocturnal behaviour and it has two pairs of udders on the lateral edge of the abdominal side coat. Young specimens of Santamartamys have a grey coat, during the transition to the adult intense red coat, moulting begins at the anterior region and moves backward. Santamartamys is a rodent, and its diet is unknown
5. Reticulated giraffe – The reticulated giraffe, also known as the Somali giraffe, is a species of giraffe native to the Horn of Africa. It lives in Somalia, southern Ethiopia, and northern Kenya, there are approximately 8,500 individuals living in the wild. The species was described and given its name by British zoologist William Edward de Winton in 1899. The reticulated giraffes and the Masai giraffes are monotypic species, Reticulated giraffes can interbreed with other giraffe species in captivity or if they come into contact with populations of other species in the wild. Together with the Rothschild giraffe, it is by far the giraffe most commonly seen in zoos and its coat consists of large, polygonal, liver-colored spots outlined by a network of bright-white lines. The blocks may sometimes appear red and may also cover the legs. The extraordinary height of giraffes is attributed to a known as necking. The giraffes with the tallest and strongest necks are victorious and allowed to reproduce, the species was described and given its binomial name Giraffa reticulata by British zoologist William Edward de Winton in 1899. Morten Thrane Brünnich classified the genus Giraffa in 1772, all living giraffes were originally classified as one species by Carl Linnaeus in 1758. Reticulated giraffes historically occurred widely throughout Northeast Africa and their favored habitats are savannas, woodlands, seasonal floodplains, and rainforests. Reticulated giraffes are herbivorous and have recorded to feed on more than 100 species of plants, with a staple of Acacia, Commiphora. Giraffe have been eating the carcass of an antelope and chewing on dried bones for their calcium content. While leaves are preferred, a giraffe will browse on many kinds of vegetation. Giraffe food preferences change according to seasons, in the dry season, giraffes feed by browsing, which typically means they eat continuously throughout the day. A male is able to eat 75 pounds of food in a single day, giraffes use their sense of smell to locate the leaves they want. They ingest everything on the branch when eating, including insects, bark, the giraffe uses its massive tongue to scrape off the leaves. Giraffes have very tough lips to guard against scratching, while the acacia tree is their favorite, giraffes have also been known to eat mareola berries and other fruits. Reticulated giraffes are ruminants, just like cattle and other ungulates, the first stomach partially digests the twigs, leaves, and whatever else the giraffe has ingested whole
6. Buettikofer's epauletted fruit bat – Buettikofers epauletted fruit bat is a species of megabat in the family Pteropodidae. It is found in Ivory Coast, Ghana, Guinea, Guinea-Bissau, Liberia, Nigeria, Senegal and its natural habitats are subtropical or tropical moist lowland forests, dry savanna, and moist savanna. It is threatened by habitat loss, mickleburgh, S. Hutson, A. Bergmans, W. & Fahr, J.2004. 2006 IUCN Red List of Threatened Species
7. Tonkean macaque – The Tonkean black macaque or Tonkean macaque is a species of primate in the family Cercopithecidae. It is endemic to central Sulawesi and the nearby Togian Islands in Indonesia and it is threatened by habitat loss. Widespread mining in central Sulawesi and in the province of Gorontalo are believed to exacerbating the problems of habitat loss
8. Trinidad dog-like bat – The Trinidad dog-like bat is a species of bat from the family Emballonuridae. It is native to Aruba, French Guinea, Grenada, Trinidad and Tobago, the bat is considered to be rare everywhere in its geographic range, although this may be untrue, as the Trinidad dog-like bat was previously confused with the lesser dog-like bat. It is an insectivore that roosts in hollow trees, hollow rotten logs on the ground, under overhanging banks. The Trinidad dog-like bat has two subspecies, Peropteryx trinitatis trinitatis and Peropteryx trinitatis phaea
