The 25 Most Endangered Primates in the World

There are 703 species and sub-species of primates in the world, from apes to monkeys to lemurs. And more than half of them are facing extinction.

Most of the endangered statuses of these primates are caused by habitat loss and destruction, like burning forests, as well as poaching and the illegal wildlife trade.

Leading primatologist and director of conservation at Bristol Zoological Society in Britain, Christoph Schwitzer says:

“This research highlights the extent of the danger facing many of the world’s primates. We hope it will focus people’s attention on these lesser-known primate species, some of which most people will probably have never heard of.”

First timers on the most endangered list include the Philippine tarsier and the Lavasoa dwarf lemur from Madagascar – a species discovered just two years ago. Other primates on the list, like the Roloway monkey from Ghana and the Ivory Coast, are on the brink of extinction.

The red colobus monkey in Africa and some of South America’s howler monkeys and spider monkeys are also threatened. These species are larger primates, which makes them easy targets for bushmeat hunting.

In a statement, Schwitzer added:

“Some of these animals have tiny populations remaining in the wild. Support and action to help save them is vital if we are to avoid losing these wonderful animals forever.”

Here is the list of the 25 most endangered primates for 2014-2016, along with their estimated remaining population size. Five of the primates are from Madagascar, five from Africa, 10 from Asia, and five from Central and South America:

    1. Lavasoa dwarf lemur – unknown
    2. Lac Alaotra bamboo lemur – about 2,500-5,000
    3. Red ruffed lemur – unknown
    4. Northern sportive lemur – around 50
    5. Perrier’s sifaka – 1,700-2,600
    6. Rondo dwarf galago – unknown, but remaining habitat is just 40 square miles
    7. Roloway monkey – unknown, but thought to be on the verge of extinction
    8. Preuss’s red colobus monkey – unknown
    9. Tana River red colobus monkey – 1,000 and declining
    10. Eastern lowland gorilla – 2,000-10,000
    11. Philippine tarsier – unknown
    12. Javan slow loris – unknown
    13. Pig-tailed langur – 3,300
    14. Cat Ba langur (golden-headed langur) – 60
    15. Delacour’s langur – 234-275
    16. Tonkin snub-nosed monkey – less than 250
    17. Kashmir grey langur – unknown
    18. Western purple-faced langur – unknown
    19. Hainan gibbon – 25
    20, Sumatran orangutan – 6,600
    21. Ka’apor capuchin – unknown
    22. San Martin titi monkey – unknown
    23. Northern brown howler monkey – less than 250 mature animals
    24. Colombian brown spider monkey – unknown
    25. Ecuadorian brown-headed spider monkey – unknown

The list comes from a report that was put together by the IUCN, Bristol Zoological Society, International Primatological Society and Conservation International and is updated every two years

Meet the Animals that Became Endangered Last Year

As we venture farther into 2016, it’s always good to reflect back on the previous year. Today, we are reflecting on animals that were either declared endangered or were upgraded from endangered to critically endangered in 2015.

1. Mexican Wolf

The U.S. Fish and Wildlife Service (USFWS) declared the Mexican Wolf as endangered earlier in 2015. Over-hunting almost wiped out the entire population 40 years ago. Now, the Mexican Wolf has new protections to conserve this rare mammal.

2. Sawfish

The USFWS placed multiple species of sawfish on the endangered species list in 2015. Several populations have fallen victim to overfishing and negative human factors.

3. Steppe Eagle

The Steppe Eagle was upgraded to “endangered” this year by the IUCN because of changes to the raptor’s environment. Habitat disturbances, such as agricultural development and a veterinary drug spreading toxic effects through its ecosystem, have caused the eagle’s population to drastically drop.

4. New Zealand Sea Lion

The IUCN classified the New Zealand Sea Lion as endangered due to “fishing-related mortality” and other threats from disease and food limitations. It is one of the rarest sea lions in the world with a population of around 10,000 and decreasing.

5. White Headed Vulture

In 2015, the IUCN upgraded the status of the White Headed Vulture from threatened to critically endangered. The vulture’s population has declined because of human threats, including poisonings and persecution.

6. Great Green Macaw & Military Macaw

The USFWS listed both the Great Green Macaw and the Military Macaw as endangered in October, 2015. The two species’ already small populations are declining due to poaching and habitat loss, fragmentation and degradation.

7. Ishikawa’s Frog

The IUCN declared the Ishikawa’s Frog, a Japanese amphibian, as an endangered species in 2015. The frog population is in serious decline because of habitat loss from dam and road construction.

8. Honduran Emerald Hummingbird

The USFWS classified the Honduran hummingbird as endangered in 2015, which gives federal officials in the U.S. the authority to prosecute anyone smuggling the bird across the border. The population has dropped to 5,000-10,000 breeding pairs after facing habitat loss and other human-related changes.

9. Narrow-striped Mongoose (also known as Boky Boky)

In 2015, the IUCN placed the Narrow-striped Mongoose, also know as the boky boky, on the endangered list. The small Madagascan mammal’s population has been negatively affected by hunting, logging and several environmental factors.

10. Splendid Toadfish

The IUCN upgraded the Splendid Toadfish from threatened to endangered in 2015 because of tourism and over-fishing. It is a mud-dwelling fish that lives in the waters of Cozumel and Belize, but has experienced habitat loss with decreasing coral reefs.
