How many animals have become extinct because of human destruction of the environment? Give more pictures, don't kill time, just names. Thank you, thank you!

Beijing time 65438+February 4th news, according to foreign media reports, in the face of the terrible extinction crisis, some animals showed amazing viability, and finally took off their "extinction" hats, including Banggai crows, turtles that feed on rhinoceros dung, pygmy glasses monkeys that look like Phoebe, Vietnamese turtles and reed warblers.

According to the recent assessment of 47,677 species of animals and plants by IUCN, there are 1729 1 species in danger of extinction, and the Rabe's trimmed tree frog (figure 1) in the picture is one of them. This frog is only found in the mountains around the Anton Valley in central Panama. Deforestation and fungal diseases are the two main culprits leading to their sharp decline. According to the Red List of Endangered Animals published by the International Union for Conservation of Nature, only one male Raber fringe tree frog has been found since 2006, and artificial propagation has also proved to be a failed attempt.

Many environmentalists say that overfishing, deforestation and global climate change will lead to the extinction crisis. Although the situation is depressing, good news comes from time to time. Some species labeled as "extinct" are still alive and have been discovered. The following eight belong to this category. Although the final result may be tragedy, their story is not over yet.

1. Indonesia reappears the trail of crows.

Indonesia reappears great chicken crow.

The picture shows a rare crow-Bungai crow. In the impression of scientists, this crow is just two specimens described in 1900, and they have long been labeled as "extinct". But surprisingly, this crow reappeared on a remote and mountainous island in Indonesia.

A biologist at the University of Michigan confirmed the rediscovery of the crowbar. He compared two birds caught in Pelen Island in 2007 with two specimens preserved in new york Museum of Natural History. The unique eye color distinguishes Banggai crows from similar beaked crows that also live in Indonesia.

Due to the small number and the accelerated deforestation rate in Pelen Island, the International Union for Conservation of Nature listed the Bungai crow as an extremely endangered species. Relevant protection measures for Bungai crow include taking actions to stop local people from hunting this kind of crow, and strengthening the protection of remaining forest habitats through developing sustainable agriculture. Developing sustainable agriculture can reduce the need for deforestation and reclamation.

2. Turtles that feed on rhinoceros droppings

Turtles that feed on rhinoceros droppings

The Arakan forest turtle living in Asia is called "Pyant Cheezar" by local people (meaning a turtle that feeds on rhinoceros dung). This turtle was found in the dense forest area of Yoma Elephant Reserve in Rakhine State, Myanmar. Environmentalists say that the name "Pyant Cheezar" is out of date, because the Sumatran rhinoceros was extinct in this area as early as 50 years ago because of hunting. Pyant Cheezar has long been listed as an extinct species, and it was not until 1994 that they reappeared in a vegetable market in China.

Many Asian turtles, including Arakan forest turtles, are popular food, but at the same time, they have no choice but to become extinct. The five Arakan forest turtles found in elephant reserve are the first batch of wild specimens since 1908. Scientists from the Wildlife Conservation Association of new york called for improving the safety of this reserve to help these animals survive. Arakan forest turtle is listed as an extremely endangered species by IUCN.

3. In Indonesia, a pygmy glasses monkey appeared, which looks like Phoebe.

A pygmy tarsier similar to Phoebe appeared in Indonesia.

On a mountain in Sulawesi, Indonesia, a primate was found, which looks like a miniature version of Phoebe's electric toy. This is a gnome glasses monkey. Scientists have long chosen to give up looking for this dwarf tarsier. In 2000, a pygmy tarsier was found in a mousetrap. This discovery aroused the great interest of Sharon Guski-Doyle, an anthropologist at AM University in Texas, USA, and she embarked on a journey of searching. In the summer of 2008, she finally found three living specimens of pygmy tarsiers, which confirmed that this small primate still exists.

The reason why IUCN lists pygmy tarsiers as a species with insufficient information is because we know very little about this species. Guski-Doyle and his colleagues hope that the rediscovery of pygmy tarsiers will put pressure on the Indonesian government to protect the primate's habitat in Lordulin National Park. There are about 60 villages in this park, covering an area of 2,000 square kilometers, and the mountain habitat of pygmy tarsiers is constantly being eroded.

4. The photos are helpful to rediscover the bayonet petrel.

The photo helps to rediscover the bayonet petrel.

Bayonet Haiyan disappeared in the 1920s and recently appeared on some islands in the northeast of Papua New Guinea. The conclusive evidence that this seabird still exists comes from more than 30 photos taken by Israeli ornithologist Hadoram Shriha. In order to find this bird with dark brown body, gray belly and tubular nose, he led a scientific research team to Bismarck Islands.

The World Conservation Union lists Haiyan as an extremely endangered species. The exact location of this seabird breeding ground is still a mystery. What worries environmentalists is that foreign mice and cats may prey on Berberis. They plan to conduct a carpet search in this area with a large number of atolls to learn more about the living conditions of this seabird.

The terrible kettle fungus disease didn't let the frog with onychomycosis hit the wall.

The terrible kettle fungus disease didn't let the frog with onychomycosis hit the wall.

Frogs are few in number, with a body length of only 1.5 inches (about 3.8 1 cm), and live in the rainforest area of northwest Australia. Because of the devastating kettle fungus disease, people once thought that this animal was extinct. In 2008, several frozen frogs were found for the first time since 199 1. The vast majority of researchers believe that the pitcher fungus makes frogs all over the world face a severe survival test, and the number of frogs suffering from onychomycosis has plummeted under the erosion of this fungus.

The frog suffering from onychomycosis is light brown and covered with dark brown spots, and is listed as an extremely endangered species by the International Union for Conservation of Nature. According to IUCN, Nepenthes is the main threat to this frog. Their habitat has been protected since 1988.

6. A rediscovered wetland bird, the big-billed reed warbler

Rediscovered wetland bird, big-billed reed warbler

Since 1867, they were discovered in the Satlej Valley in India, and the reed warbler with big mouth has never appeared in people's sight. In 2006, people finally found this little-known wetland bird again in a place more than 1900 miles (about 3058 kilometers) from a sewage treatment plant on the outskirts of Bangkok, Thailand. The results of DNA test confirmed this discovery. Six months later, a mislabeled reed warbler specimen was found in the showcase of the Natural History Museum in Trane, England.

IUCN listed the big-billed reed warbler as a species with insufficient data, and said that it may be a very rare bird, but it may also be a "big family", because the shape of the big-billed reed warbler is similar to other reed warblers, and its real number is underestimated. Although little is known about this kind of bird, scientists think that the big-billed reed warbler found in Thailand is unusual. Compared with Thailand, this bird is more famous in India.

7. The Vietnamese turtle is back.

The Vietnamese turtle is back.

Vietnamese sea turtle Swinhoe is an extremely endangered species. Scientists once thought that this kind of turtle was extinct in the wild. But they were found in a lake in northern Vietnam. This Swinhoe soft-shelled turtle in the picture is the only known wild specimen.

At that time, researchers from the Metropolitan Park Zoo in Cleveland, USA, formed an expedition to look for this soft-shelled turtle. Before Thanksgiving in 2008, they experienced a "labor pains". At that time, the Vietnamese turtle washed down the dam and fell into the lake because of the flood. A local fisherman caught it and almost sold it to a guy who wanted to make soup with soft-shelled turtle for 1000 dollars, but after being persuaded by environmentalists, he finally put the soft-shelled turtle back into the lake.

The World Conservation Union lists Vietnamese tortoise as an extremely endangered species. The Metropolitan Park Zoo said that a large number of deaths of this reptile were mainly caused by human hunting. Some people catch and kill them for food, or use their bones for traditional medicine. Habitat loss and environmental pollution along major rivers are also the reasons for the sharp decline of turtle population in Vietnam. Swinhoe turtle is the largest freshwater turtle in the world, with a maximum weight of 300 pounds (about 136 kg), a maximum length of 3 feet (about 0.9 1 m) and a life span of over 100 years.

8. Will ivory-billed woodpeckers take off their extinct hats?

In April 2005, after scientists announced that the ivory-billed woodpecker lived in a swamp in Arkansas, USA, birdwatchers all over the world were excited. This woodpecker was last seen in 1944. After this discovery, experts traveled all over the swamp forest in the southeastern United States, hoping to prove that this unique bird really existed, but in the end they returned empty-handed.

Some ivory-billed woodpeckers may still live in nearby inaccessible swamps, but in 2009, scientists from Cornell University's ornithology laboratory ended their five-year search because they found nothing. Environmentalists are calling for a search in Cuba, where ivory-billed woodpeckers may still exist. IUCN listed the ivory-billed woodpecker as an extremely endangered species.
