Key Takeaways Show

Most Endangered Primates

Primates play a crucial role in maintaining the diversity of the planet and unquestionably help maintain the health of the global ecology. Unfortunately, the majority of primate species are on the list of endangered species due to the sharp decline in their population.

Large-scale habitat loss, particularly from the burning and clearing of tropical forests, food hunting, and the illegal wildlife trade, is eliminating our closest living relatives.

60% of the primate species are on the verge of extinction, and 75% of their populations are dramatically decreasing.

That’s according to the most recent edition of “Primates in Peril: The World’s 25 Most Endangered Primates”, compiled by the primate specialist group The International Union for the Conservation of Nature (IUCN), the Bristol Zoological Society (BZS), Global Wildlife Conservation (GWC), the International Primatological Society (IPS), Species Survival Commission (SSC), and Conservation International scientists just updated their list of the 25 most endangered primates on Earth (CI). They update it every two years.

The rising threat to primates is serious for the entire world. Therefore, the only important action that can prevent them from going extinct in the near future is to conserve them right away.

Here’s the list of the Top 25 most endangered primates –

1. Lake Alaotra Gentle Lemur

Lake Alaotra Gentle Lemur

The Lac Alaotra Bamboo Lemur, also known as the highly endangered Lake Alaotra Gentle Lemur, is referred to as the bandro by locals. The only primate that only inhabits wetlands, this lemur is found in Madagascar’s Lake Alaotra marsh, which is fading fast.

It feeds on papyrus reeds specifically and doesn’t eat bamboo. It typically has a brownish-gray appearance with a body and tail length of 40 cm each. It is between 1.1 and 1.4 kilograms in weight.

Lemur hunting for food has been prohibited thanks to conservation efforts, but the Lake Alaotra marshes’ agricultural use still threatens the species’ population.

Scientific Name

Hapalemur alaotrensis

Current Population

A 2018 IUCN estimate put the total number of Lac Alaotra lemurs at 2,500.

Reasons Why They are Endangered

The main factors that have led to the critically endangered status of the Alaotran gentle lemur are hunting for food and a pet, destroying habitat, and burning the marshland.

Status of conservation

The International Union for Conservation of Nature lists this primate as a critically endangered species.

2. James’ Sportive Lemur

James’ Sportive Lemur

The Manombo Special Reserve area in southeast Madagascar is home to the James’ Sportive Lemur. In forest reserves, there are currently two populations. Lemurs are taken out of their burrows by hunters using traps and cutting down the trees they live in.

The primary and secondary lowland forests of southeast Madagascar are home to Jame’s sportive lemur.

This lemur is 60 to 67 cm long, with a tail that is between 28 and 32 cm in length, making it one of the larger sportive lemurs.

Scientific Name

Lepilemur jamesorum

Current Population

Only 1,386 Manombo sportive lemurs are left in existence,

Reasons Why They Are Endangered

Their critically endangered position and an estimated population of 1,386 individuals were caused by deforestation, pet trading, and hunting for bushmeat.

Status of Conservation

The IUCN study states that James’ Sportive Lemur is a critically endangered primate.

Lepilemur jamesorum1,386Deforestation, pet trading, hunting for bushmeatCritically Endangered


3. Tana River Red Colobus

Tana River Red Colobus

This red colobus lives along the Tana River in northern Kenya. Its tail is more than 31 inches long, and its body is almost 2 feet long. This critically endangered monkey has a red or dark red coat. In northern Kenya, close to the Tana River, the red colobus has its homes.

This species’ population has declined as a result of the development of hydroelectric dams and the region’s quickly expanding human population. The region’s vegetation is changing as a result of the dam construction, which lowers the availability of suitable food.

Scientific Name

Piliocolobus rufomitratus

Current Population

There are less than 1,000 individuals left, according to the IUCN, making it critically endangered.

Reasons Why They Are Endangered

The development of hydropower dams and the region’s fast-rising human population are the main factors contributing to their declining population. Certain parasite illnesses and human hunting are further important contributors to their endangerment.

The vegetation along the Tana River is undergoing change as a result of the construction of dams. As a result, the red colobus’ ideal meal is almost impossible to get; as a result, they are suffering and becoming threatened.

Status of Conservation

The red colobus of the Tana River is regarded as a highly endangered species.

Piliocolobus rufomitratus< 1,000Hydropower dams, human population growth, parasites, human huntingCritically Endangered


4. Ecuadorian White-Fronted Capuchin

Ecuadorian White-Fronted Capuchin

In the ecoregions of Chocó and Tumbes in Ecuador and Peru, only 1% of the original range of the Ecuadorian white-fronted capuchin is still present.

The inhabitants, especially those who reside near corn, banana, cocoa, and plantain plantations, view these monkeys who live in trees as pests.

In mangrove areas, they offer competition for crab hunting. With an unknown number of mature individuals, this animal is classified as highly endangered.

Scientific Name

Cebus aequatorialis

Current Population

There are currently just 300 Ecuadorian White-Fronted Capuchins in the wild.

Reasons Why They Are Endangered

Since Cebus aequatorialis has been subject to numerous dangers for a long time, it is currently considered as an endangered species. They frequently face dangers like Grazing, fragmenting of the habitat, Unlawful mining, anthropogenic elements, and deforestation.

10. Bemanasy Mouse Lemur

Bemanasy Mouse Lemur

The Bemanasy mouse lemur lives in a patch of forest in southeast Madagascar. It was identified as a distinct species in 2016.

This species of mouse lemur is the largest of all of them. There is a greyish-brown coat that appears on their tail and back. The many species of mouse lemurs are thought to be cryptic species, differing very slightly morphologically but differing greatly genetically.

Recent data suggests that these calls, which are extremely varied, differ from one another. Since mouse lemurs are nocturnal animals, it is possible that they did not evolve distinct facial features but rather a variety of hearing and vocal systems.

Scientific Name

Microcebus manitatra

Current Population

The precise number of this species’ remaining individuals is unknown, but it is extremely low.
