Are there animals in the world that scientists mistakenly believe are extinct but have not actually been discovered?

The first is the crested ibis. As a symbol of the Japanese royal family, this bird can be seen in many works of art, but it is difficult to capture it in real life. It is said that in the 1970s, there were only 7 birds left, which actually meant functional extinction. Because they are too rare and destroy the ecological environment, in order to prevent extinction, people can capture them in artificial breeding bases. With the help of humans, the number of crested ibises can be restored. Soon, Japan announced that there were only three crested ibises left. ?

However, my country’s natural science survey team discovered two crested ibis nests in Shaanxi Province. Finally, under the protection of the team members, the number of crested ibises increased, once reaching more than 1,500. Even now, the number of crested ibises is very small, but not as high as the danger of extinction. According to scientists, only about 11% of all leopards have this disease. Leopards are endangered wild animals, so you can imagine how rare the number of panthers is. In Africa, there has been no evidence of its existence for more than a hundred years.

So many scientists say that black panthers are actually completely extinct in the world, but until Wilblood-Lucas, he was a British wildlife photographer. Leopards know it well. Living in Africa and Asia, have you ever heard of a black panther? In fact, as you can tell from the name, the fur is black. Why it is black is mainly because of melanism, which is not uncommon among animals. ?

Due to excess melanin in the body, not only will the skin color be affected, but the eyes will also undergo certain changes. Paul's giant earthworm, which is much longer than the earthworms we usually see, was originally thought to be extinct in the 1980s. But scientists discovered an adult Paul's giant earthworm in 2005, and again in 2009 by Idaho State University professor Judy Johnson-Maynard. Later, research revealed that Paul the Giant earthworm only lived in the U.S. states of Iowa and Washington, as well as in the Pulse region known as the Prairies.
