One, whales.
Whales are divided into two groups, baleen whales and toothed whales. Whales belong to the phylum Chordates, vertebrate subphylum, mammals, euphropods, containing about 98 species of fetal mammals living in the oceans and rivers.
There are more than 30 species in China's waters. All species of whales, with the exception of a few, live in freshwater, the rest inhabit the ocean. Whales themselves are vaguely defined, and whales can contain all cetaceans, as well as cetaceans of specific families. All dolphins are also included in the whales. Whales are mainly divided into two species: baleen whales (mysticeti) and toothed whales (odontoceti).
Baleen whales are fewer species but large, with the smallest known species also exceeding 6 meters in length, and the world's largest animal, the blue whale, also belongs to the baleen whale. However, the size of toothed cetaceans varies greatly, with the smallest species only about 30 cm long and the largest sperm whales growing more than 20 meters. Whales do not belong to the fish, but to mammals.
Two, lions.
Lion (scientific name: panthera leo; English name: lion): Referred to as lion, ancient Chinese name fox. It is a large cat that lives in Africa and Asia, is the largest average weight cat in existence, and is the only hermaphrodite in the world.
Lions are large, homogeneous, with medium-long limbs and toes. The head is large and round, the snout is short, and the sense of sight, hearing, and smell is very developed. The canine teeth and split teeth are extremely developed; the upper split teeth have three tooth tips, and the lower split teeth have two tooth tips; the molars are more degenerate, and the diameter of the crown is smaller than the height of the lateral incisors. Soft fur. The forefoot has 5 toes and the hind feet have 4 toes; the claws are sharp and retractable. The tail is more developed. Known as the "King of the Prairie", it is the top cat carnivore in Africa. Wild African male lions weigh an average of 240 kg and can reach a total length of 3.2 meters. Lions have short hairs, light gray, yellow or brown in color, and male lions also have long manes, such as light brown, dark brown, black, etc., and the long mane extends to the shoulders and chest.
It lives in savannas and meadows, but also in shrubs and dry forests. Meat-eating, often ambushing and killing other warm-blooded animals. It is found in the African steppe and in Asia and India. Lions live for 10 to 14 years in the wild, and live longer in captivity, generally for more than 20 years.
Three, wolves.
Wolves (Latin name: canis lupus linnaeus), protected animals with a "three haves" level. There are 46 subspecies, medium-sized, well-proportioned, slender limbs, and toe-like, which is conducive to running fast. The head and palate are pointed, the face is long, the nose is prominent, the ears are pointed and upright, the sense of smell is sensitive, and the hearing is developed. Canine teeth and split teeth are well developed; the upper molars have obvious tips, the medial side of the lower molars have a small tip and heel tip; the diameter of the molar crown is greater than the height of the lateral incisors; the tooth type is. The hair is thick and long. The forefoots are 4 to 5 toes, and the hind feet are generally 4 toes; the claws are thick and blunt, and cannot be or slightly retractable. The tail is hairy and more developed. Good at running fast and long distances, living in groups, often chasing and hunting. Feeds on herbivores and rodents. Its natural habitats are forests , deserts , mountains , boreal grasslands , coniferous forests , and grasslands. It is found all over the world except Antarctica and most of the islands. Similar in appearance to dogs and jackals, the foot is long and thin, the eyes are oblique, the upper jawbone is pointed, the mouth is wide and curved, the ears are erect, the chest is slightly narrow, and the tail is straight and droopy between the two hind legs. The coat color varies with the origin of origin, with a brownish yellow or grayish yellow, slightly mixed with black, and the lower part is white. It has a wide range of habitats and strong adaptability, and wolves live in mountains, forest areas, grasslands, and even ice sheets. Nocturnal activity, keen sense of smell, good hearing. Alert, suspicious, good at running, strong endurance, often using the method of exhaustive pursuit to obtain prey. Wolves are carnivores, mainly feeding on deer, antelopes, rabbits, but also eat insects, rats, etc., and can tolerate hunger. Wolves are predators, and wolves are formed as nuclear families, including a spouse and their children, and sometimes adopted juvenile wolves. Wolves are typical food chain sub-predators. Usually acting in groups, wolves prey on domestic animals such as sheep, so they were hunted by humans by the end of the 20th century, and some subspecies such as the Japanese wolf, the Newfoundland wolf, the Florida black wolf, and the Kenai mountain wolf were extinct. The exact number of present-day subspecies remains uncertain.
Four, mongoose.
The fox (scientific name: suricata suricatta), with a head and tail length of 42-60 cm, is a small mammal. Bulky. The limbs are short , with 5 toes on the hind feet , webbed between the toes ; the tail is long and round , about 2/3 of the body length , covered with small scales and sparse hairs. The dorsal coat is dark brown with a yellow tip and dark brown hairs; the tail is two colors, the top is brownish black, and the base and lower part of the tail are pale yellow.
It inhabits grasslands and open plains, and its distribution depends on the soil type, with tropical hard soils as a promised soil, mainly in deserts or sand dunes of terrestrial biomes.
They are very social animals, living in colonies of up to forty, specializing in burrowing, resting at night and working during the day, feeding mainly on insects, but they also eat lizards, snakes, spiders, plants, eggs and small mammals. There is no strict seasonality in breeding. The gestation period is about 130 days, and each litter is 6-8 litters, which can be delivered twice a year. It is found mainly in the Kalahari Desert of South Africa.
Five, wildebeest.
Wildebeest (genus name: connochaetes zimmermann, 1780, English name: wildebeest), also known as wildebeest, is a large herbivorous animal that lives on the African steppe. Taxonomically , it belongs to the genus Wildebeest of the subfamily Oryx of the bovine family. There are two species of wildebeest, the white-tailed wildebeest and the spotted wildebeest.
Wildebeest is a large antelope that lives on the African savannah and grows a bull's head, horse's face, and sheep's whiskers. The head is thick and shoulder-width, much like a buffalo; the rear is slender, more like a horse; and the neck has black mane. The whole body has long hairs, smooth and has short markings. The body ranges from blue-gray to dark brown, with a black face, tail, beard, and markings, and the color varies according to subspecies, sex, and season. Wildebeests are large, weighing up to 270 kilograms, and generally have a lifespan of about 15 to 20 years.
It is mainly found in sub-Saharan Africa.
Wildebeests are large herbivores. The body is large, the limbs are thick, the shoulder height is larger than the hips, the tail is shorter, the snout nose is high and curved, the body length is about 1.8 meters, and the adult male can reach more than 2 meters. The shape resembles an ox, the body is strong and between the goat and the antelope, so it is also called wildebeest. The snout nose and limbs are black. Wildebeests have fluttering manes and whiskers, growing into clusters of tails, both males and females have curved angles, bending from the top of the head to the sides, and then twisting backwards and upwards, the horn tips are wide and thick inward, very smooth, and there are long beard-like long hanging hairs under the jaw and under the neck. Adult males weigh 200 to 270 kg and are 125 to 145 cm tall, while female wildebeest weigh 168 to 233 kg and are 115 to 142 cm tall. The horns are thick and curved to the sides, generally the male horn is 55 to 80 cm long, and the female horn is 45 to 63 cm long, hence the name wildebeest.
Six, antelope.
In the Classic of Mountains and Seas, the Western Mountain Classic mentions the líng, which is now the antelope. Antelope is a collective term for a class of even-hoofed cattle. There are a total of 86 species of antelope animals, belonging to 11 families and 32 genera. For taxonomy, antelope does not have a specific specific reference to which family or genus. Antelopes are characterized by hollow and strong horns, which are ruminants that distinguish them from cattle and sheep. There is a consensus on antelope as a taxon, and the "antelope expert group" established by the Species Survival Committee treats this group of animals as a unit of zoological research and conservation.
Seven, vultures.
Birds of the genus Vulture are large birds of prey. Length 80-150 cm, tail length 24-40 cm, wingspan 220-300 cm, weight 6-12 kg. It is large in size, with a well-developed beak but underdeveloped claws. The beak has an arc-shaped vertical protrusion at the end of the beak, suitable for tearing prey to swallow; the base has wax membranes or whisker-like feathers; the wings are strong, the wings are wide and round and blunt, the fan wings and soar, the fan wings are slower than the Falcon family; the tarsals are mostly relatively long, about the length of the tibia. Females are significantly larger than males.
The Eurasian vulture is a large brown vulture. The head and neck feathers are degenerate and exposed. The base of the neck has a soft, nearly white jaw, and the head and neck are yellowish and white. The body and upper wing feathers are pale brown, contrasting with the black feathers on the remaining wings and tail. This contrast is particularly pronounced in young feathers, which have particularly pale upper wing feathers. Sub-adult birds have brown jaws. Much like the alpine vulture, the difference is that the upper body is yellowish brown instead of light earth yellow when flying, and the light feathers on the thorax are thinner. It differs from vultures in that it is lightly colored on the underbody and has a flat or rounded tail rather than a wedge. The iris is brown; the corners of the mouth are colored with black wax film; the feet are dull greenish yellow.
The head and upper part of the neck of the alpine vulture are covered with dirty yellow hair-like feathers, to the lower neck feathers gradually turn white and become down feathers, and at the base of the neck there are long, lanceolate tufts of feathers forming a collar around the neck, pale yellow or yellowish brown, with a central white feather axis. The dorsal and wingtops are pale yellowish brown , the feathers are browner in the centre , forming irregular brown spots , the outer large coverts , flight feathers , and tail feathers are dark brown , and the inner secondary flight feathers have pale tips. The upper thorax is densely packed with white down feathers and is covered with pale brown thorax spots, while the rest of the lower body is pale yellowish brown, and the and subtail coverts are all white with unclear feather lines. Juveniles have brown heads and more down feathers than adult birds. The upperparts are dark brown , the covert feathers on the back , shoulders and wings have thick yellow-white longitudinal stripes , and the primary flight feathers and tail feathers are dark brown. The underparts are dark brown with pale feathers.
