1. West African Black Rhinoceros (2006)
The West African Black Rhinoceros went extinct in 2006. It had two horns, the first measuring 0.5-1.4 m, and the second 2-55 cm, and its horns were considered to have medicinal value, which is believed to be the main reason for its extinction, but this belief has no grounding in scientific fact. Like most black rhinos, they're nearsighted and have to rely on local birds to detect incoming threats.
2. Baiji or Yangtze River Dolphin (2006)
The Baiji or Yangtze River Dolphin went extinct in 2006. They lived in the Yangtze River in China. Nicknamed "Goddess of the Yangtze," and were regarded as the goddess of protection by local fisherman. Their population declined drastically in just a few decades, as the massive pollution caused by China's industrialization took hold. Now the species is considered "functionally extinct," meaning that even if there are a few old creatures alive, no new ones will be born.
3. Po'ouli (2004)

For example, the male was a faded grayish brown during the summer, and they were decorated with black in several places on the body such as the mane, forelegs, and forehead, whereas the female lacked the black coloring. Although there used to be a cloned ibex after the real Ibex went extinct, it died shortly after birth from lung complications. The Spanish government was blamed for failing to act in time to save the Ibex.

It can reach a size of 55 to 65 millimeters. The wings are pure white with a broad black tip on the apexes of the forewings. Unfortunately, we can only enjoy them from photos now thanks to pollution, making their habitat a chemical laboratory.
6. Golden Toad (1989)
The Golden Toad permanently disappeared in 1989. This bright amphibian was found in the high-altitude ridges of Costa Rica. Males and females are different in color, size, and other delicate traits. For example, females were typically larger than males being 42 to 56 mm compared with 39 to 48 mm body size of the males. They also had more colors including; black, yellow, red, green, and white. The males meanwhile were only orange and sometimes slightly mottled on the belly. They were also the victims of modern issues like pollution, global warming, and fungal skin infections.
7. Javan Tiger (1979)

Males had a mean body length of 248cm (98 in) and weighed between 100 and 141 kg (220 and 311 lb). Females were smaller than males and weighed between 75 and 115 kg (165 and 254 lb). They were native to the Indonesian island of Java. But facing the rapidly increasing loss of habitat and food, they failed to compete with humans and went extinct finally.

The Dutch Alcon Blue Butterfly permanently disappeared in 1979. This beautiful butterfly was endemic to the Netherlands and it's also called Maculinea Alcon. The last Dutch Alcon Blue was seen in the wild in 1979. Increases in farming and construction had a negative impact on their habitat and caused it to struggle for food.
9. Round Island Burrowing Boa (1975)

The Moghul emperor was said to have had 1,000 cheetahs at one time for assisting in his royal hunts."

11. Barbary Lions (1942?/1960?)
It's not clear when the wild Barbary Lions went extinct, some said around 1942, others said as late as 1960.

The head-to-tail length of stuffed males in zoological collections varies from 2.35 to 2.8 m, and females measure around 2.5 m." They used to be shining "stars" not just in Africa but also Europe, but still, couldn't escape the adversity of being slaughtered. The good news is that we can see the domesticated Barbary lion today.

16. Warrah (1876)
The Warrah went extinct in 1876. Warrah, or Falkland Islands wolf, may the only mammal native to the Falkland Islands. Their long-time solitary life makes them less experienced in contact with the human, so they exposed habitat to the settlers, which caused their race disappear.
17. Atlas Bear (mid 19th)
The Atlas Bear went extinct in the mid 19th century. As an old "native" species of Africa, they lived a free life in the northwestern region of the continent, around the Atlas Mountains.
