It has been proposed that the Earth has experienced five mass extinction events, and the sixth is coming, and many animals are already in danger, such as the world's top ten critically endangered species, they are ai ai lemur, tree kangaroo, toothed dove, pangolin, giant soft shell turtle, crown seal, owl parrot, high-nosed antelope, kudu horned goat, western blunt salamander,
1. Ai Ai Lemur
Lemurs belong to the primate proto-monkey suborder Lemur family. Wild lemurs are found only on the island of Madagascar. The lemur has some similarities in appearance to bats, and it is the only species of primate mammals that use echolocation capabilities to hunt, and lemurs are unusually distant relatives of humans. According to the IUCN, lemurs are at risk of extinction. The increasing disappearance of habitats, combined with other threats, indicates that the lemur species has become vulnerable. To effectively protect the lemur, scientists are struggling to understand the habits and number of this mysterious animal.
2. Tree kangaroos
Tree kangaroos are kangaroos that live in trees. They are found in the rainforests of New Guinea, the far north-east of Queensland and neighboring islands. Although most live in mountainous areas, several species inhabit lowlands, such as the soap tree kangaroo. Most tree kangaroos are listed as endangered for hunting and loss of habitat.
3. Tooth-billed dove
The tooth-billed dove (scientific name: didunculus strigirostris) has only 1 genus and 1 species, and the mandible has two "teeth". Medium in size, ground or arboreal. The beak is short, the base is mostly soft and waxy; the wings are well-developed and good at flying; the tail is short and round; the legs are short and robust, webless, and the hind toes are on the same horizontal plane as the front three toes or lack the hind toes. Food is mostly seeds and fruits. It is found only on three small Pacific islands, including Samoa. Due to human activities, cats, dogs and other predators have been introduced, resulting in the endangerment of the epidemic. It is the national bird of Samoa.
4. Pangolins
Pangolin (scientific name: manis pentadactyla): head length 42-92 cm, tail length 28-35 cm, weight 2-7 kg; scales parallel to the body axis, a total of 15-18 columns. There are also 9-10 longitudinal scales on the tail. The scales are brown, the edges of the scales of the elderly are orange-brown or grayish brown, and the scales of the juveniles that have not yet been horned are yellow. The kiss is slender. The skull is large and conical in shape. Its natural habitats are moist woods in hills, foothills, and plains. Loves the heat and can climb trees. It can dig holes in the dirt that are 2-4 meters deep and 20-30 cm in diameter. The end of the nest is about 2 meters in diameter. Feed on termites, ants, bees, or other insects with long tongues. It is found in Bhutan, China, India, the Lao People's Democratic Republic, Myanmar, Nepal, Thailand and Viet Nam.
Pangolins are hunted extensively in Asia for food and traditional medicine. The species has been significantly reduced in its native habitat, and the Chinese pangolin has been listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora since 1990, stating that any commercial use of hunting from the wild is prohibited. Exports and trade are prohibited in a number of different countries and regions, including Bangladesh, China, India, Laos, Myanmar, Nepal, Thailand and Vietnam. In China, it is a national second-level protected animal, and it is forbidden to hunt and eat, illegally hunt, smuggle or sell, and can be sentenced to more than 5 years in prison, and the maximum sentence in the case is serious.
5. Soft-shelled turtle
Soft-shelled turtles, also known as turtles, refer to soft-shelled aquatic turtles belonging to the turtle family Turtle family. Soft-shelled turtles are found in light currents and lakes in Asia, Africa and North America. Soft-shelled turtles are characterized by round, pancake-like soft dorsal shells, webbed legs, a long head and neck, and nostrils that grow in front of a fleshy long nose (the female is significantly larger than the male).
6. Crowned seal
Crowned seals are a species of seal family that lives in the Arctic. Male crested seals have a swollen skull crown and nose ball, and when they are provoked, they exhibit this peculiar sign. The average male is 2.5 m long and weighs 192 to 352 kg; the female is 2 m, 145 to 300 kg.

Staple foods are squid, salmon, octopus, herring, cod and so on. It is found in the Arctic and subarctic regions of the North Atlantic; the species has been considered endangered by scientists.
7. Owl parrot
Parrot (scientific name: strigops habroptila), called "kakapo" in New Zealand, is the local Maori language, kaka is "parrot", po means "night". Chinese translates to Owl Parrot quite godlike, because the face of the Owl does resemble a nocturnal owl. It is a nocturnal parrot covered with yellow-green dots and is endemic to New Zealand. It has a distinctive arrangement of face plates and feathers unique to the order Owl, a unique receptor - feather whiskers, a large, gray beak, short legs and big feet, wings and a relatively short tail. Its different habits make it a rather unique breed – it is the only parrot in the world that cannot fly, and its size is the largest in its kind.
Nocturnal, herbivorous, exhibiting a gender-alien body structure, a slow basal metabolic rate, males not responsible for caring for the young, and the only parrot that practices polygamy and a courtship mating system. It is mainly herbivorous, eating native plants, seeds, fruits and pollen. It is one of the longest-lived birds in the world. It is a critically endangered species. It is found in southern New Zealand, Stewart and other islands.
As of 2012, there were 126 parrots, including 78 adult birds.
8. High-nosed antelope
High-nosed antelope (scientific name: saiga tatarica): Alias Saiga antelope, belongs to the bovine family. Medium in stature, 1.2-1.7 m long, yellow-brown back, white buttocks, tail and abdomen, short and smooth summer hairs; light, dense and long winter coats; thin limbs; nasal bones are highly developed and curled, covered with hairs, glands and mucus tubes, and each nostril has a special mucosal sac that heats and becomes more moist to adapt to the cold environment of the plateau, and is also related to the sensitive sense of smell. Because the nose is particularly large and puffed, bent downwards, and the nostrils are at the tip, it is named "high-nosed antelope". Only males have horns.
It inhabits desert and semi-desert areas. Living in small groups, sometimes forming large flocks of hundreds or even thousands of animals. Winter is mostly active during the day, and in summer, it is mainly active in the morning and evening. Good at running, fast, and endurance. Mating in early autumn and early winter. There is a fierce competition between males for females. Because antelope horn is a valuable medicinal herb and has been hunted for a long time, China's wild population has become extinct, originally distributed in southern Russia, Mongolia and northern Xinjiang, China, and is now only found in Russia.
9. Kushina goat

There are fewer than 2,500 existing wild populations, which have been listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora. In addition, this species is pakistan's national animal and is strictly protected by Pakistani laws.
10. Blunt salamander
The blunt-mouthed salamander , also known as the Mesa, also known as the hexagonal dinosaur , is found only in one lake in Mexico and is an amphibian with the order Cymbidium axoruptera. Famous for its peculiar cries , it is a popular amphibian. Hexagonal dinosaurs are well known as "juvenile mature" species of amphibians (from birth to sexual maturity and spawning, they are in the form of juveniles). The larvae live in the water all their lives and also lay eggs in the water. The variable body color is also one of their charms, there are more than 30 kinds of worldwide, common are ordinary body color, albino species (black eye), albino species (white eye), golden body color (white eye) and all-black individuals.
Wild populations are threatened due to the development of Mexican cities. In Mexican markets, blunt-mouthed salamanders are sold as food and play an important role in Aztec cuisine. They are listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora and are listed in the IUCN Endangered Wildlife.
