8. Hainan Gibbon
The Hainan Gibbon also referred to as the black-crested Hainan Gibbon, is one of the rarest primates in the world. This particular species of gibbon, which is a small ape, is only found in one particular forest range on the tropical island Hainan off the southern coast of China. All attempts to breed this species in captivity have failed. There are only approximately 25 of these gibbons left in the wild.
9. Greater Bamboo Lemur
Also known as the broad-nosed gentle lemur and the broad-nosed bamboo lemur (because of its broad nose), the greater bamboo lemur is found only in southeastern regions of Madagascar. This lemur only eats bamboo, which has left experts baffled as to how its body processes the cyanide present in bamboo shoots – a chemical extremely toxic to people. Bamboo is frequently cut down illegally and sold to create a variety of different items, which has caused a steady decline in the population of this lemur. There are an estimated 200-500 of these lemurs in the wild, and it is listed as critically endangered on the IUCN Red List.
10. Red Wolf
The red wolf is a member of the canine family, named after the reddish-tawny shade of its fur. This wolf is native to river forests and swamps across the southeastern states of the US. There are approximately 200 of this species in captivity, but only 40 in the wild. Because there is still much debate regarding the lineage of the red wolf, that is, whether it is a mixture of a wolf and a coyote or a different species, this species has not been considered endangered for certain. It is listed as critically endangered on the IUCN Red List.
11. Spoon-Billed Sandpiper
This bird spends winters in Southeast Asia and the mating season in north-eastern Russia. It is a small wader, which means it inhabits coastal shore and usually wades through the water to forage for food in mud and sand. Their population in captivity and in the wild collectively is estimated to be between 250 and 500. The IUCN lists this bird as critically endangered.
12. Roloway Monkey
This black, white and brown monkey is a native of the tropics of West Africa. They live in the canopies of the old-growth forests of the Eastern Ivory Coast and Ghana. They are frequently hunted for their bushmeat, which has caused a heavy decline in their population. All populations of this monkey in Ghana’s Bia National Park have been completely wiped out. There are only 2000 mature individuals of this species In the wild, resulting in these species being categorized as endangered on the IUCN Red List.
13. California Condor
This gorgeous fowl is the largest bird in North America with a wingspan of 10 feet. In 1982, there were only 22 California Condors left. This vulture has been extinct in the wild since 1987, at which point the few remaining wild birds were placed in captive breeding programs across Arizona and Utah. Thanks to these programs, 2019 saw the hatching of the 1000th California condor chick. It is, however, very much still considered a critically endangered species according to the IUCN Red List.
