The Koolakamba is a supposed large ape said to lives in the thick jungles of Equatorial Africa. Most reports about it come from the 19th century, describing it as having features intermediate between those of a chimpanzee and a gorilla.

Today, scientists usually think these sightings are just unusual examples of known apes. However, the Koolakamba is still an interesting topic in cryptozoology.

Who or What Is Koolakamba?

The Koolakamba is a mysterious primate from Central Africa that became known through stories from European and American explorers in the 1850s. Its name comes from the Nkomi and Bakalai languages, referring to its unique call. Early reports say it was called “Kooloo” for its cry, and “Kamba” is a Commi word that means “to speak”.

Local tribes saw the Koolakamba as distinct from both chimpanzees and gorillas, treating it as a separate kind. People often described it as having a more human-like face and behavior than other apes.

Some early scientists tried to classify it as a new species, Pan troglodytes koolookamba, but modern biology has not found enough evidence to prove it is a separate species or a true hybrid.

Cryptozoology A To Z

What Does Koolakamba Look Like?

People who describe the Koolakamba often focus on its mix of features. They usually say it is bigger than a chimpanzee but smaller and lighter than a gorilla.

One of the Koolakamba’s main features is its very dark, almost black face, which is flatter than a chimpanzee’s. Its skull is round with high cheekbones and hollow cheeks, and some people have even compared its face to those of certain human groups.

The Koolakamba is said to have large, human-like ears and a strong brow ridge. Its body is covered in black hair, and its front teeth meet evenly, making a flat surface for chewing. People also say it has a short, wide pelvis, which might help it walk on two legs more often or more steadily than other African apes.



Habitat

People say the Koolakamba lives only in the thick, tropical forests of West Central Africa. Most sightings have happened in what is now Gabon, especially near the Ogooué and Ovenga Rivers. These forests are very humid, get a lot of rain each year, and have a dense canopy that keeps much sunlight from reaching the ground.

The land in these areas is rough, with both low swamps and high cloud forests. There is plenty of fruit, like the tondo, a soft, pear-shaped fruit that many primates in the region eat.

The Koolakamba is believed to live near groups of chimpanzees and gorillas. Still, people often say it stays on the edges of these groups or lives alone in hidden areas. Because these forests are so remote and densely vegetated, it is very hard for scientists to find and study rare primates like these.

Paul Du Chaillu (Ovenga River, 1860)

The best-known story about the Koolakamba comes from explorer Paul Du Chaillu, who traveled in equatorial Africa. While walking near the Ovenga River, he heard a strange cry he had never heard before.

When he found where the sound was coming from, he saw a large ape sitting high up in a tree. After the animal was shot and brought down, Du Chaillu noticed it looked very different from both chimpanzees and gorillas. He measured it at four feet three inches tall and pointed out its very round head and ears that looked like a human’s. His local guides said right away that it was a Koolakamba.

The Case of Mafuca (Dresden, 1874)

In 1874, an ape called Mafuca was brought from the Loango coast to the Dresden Zoo. Mafuca was very large and had a wild, hard-to-control nature. Scientists who studied her could not agree on what species she was. Some thought she was a gorilla, while others said she was a chimpanzee.

Some experts at the time concluded that Mafuca was a genuine Koolakamba. Drawings of her show a black face, a nose like a gorilla’s, and strong brow ridges, matching what Du Chaillu had described before.

Evidence & Investigations

Most of the evidence for the Koolakamba comes from old specimens, reports from 19th-century naturalists, and some recent photos. Paul Du Chaillu gave the first major evidence by bringing back skulls and skins from his hunts, which were later sold to the Natural History Museum in London. Still, many scientists at the time argued that his findings were just unusual examples of known species.

In the 20th century, people started to see the Koolakamba more as a cryptozoological mystery than a real species. In 1929, Dr. Robert Yerkes reported seeing “unclassifiable apes” that seemed to be between chimpanzees and gorillas. In November 1996, a photo of a primate named Antoine at the Yaounde Zoo in Cameroon brought new attention to the topic.

This ape had a much wider face and bigger skull than a normal chimpanzee, so some people thought it might be a modern Koolakamba. However, DNA tests have never shown that a separate hybrid species exists in the wild, and most of these “in-between” apes are now seen as just large male chimpanzees.



Theories

The Chimpanzee-Gorilla Hybrid Theory

The most common theory among cryptozoologists and early explorers is that the Koolakamba is a natural mix between a male gorilla and a female chimpanzee. People who support this idea say its size and mixed features are proof of cross-breeding.

Even though gorillas and chimpanzees are close genetically, most scientists today think it is very unlikely they would mix in the wild. This is because they have different social lives, mating habits, and belong to different groups (Pan and Gorilla).

Individual Morphological Variation

A more widely accepted scientific idea is that the Koolakamba is not a new species or a hybrid, but just a type of chimpanzee with unusual features.

Like people, chimpanzees can look very different from each other, with things like darker skin, bigger brow ridges, or different ear shapes. This theory says that explorers like Du Chaillu probably just saw a special group of chimpanzees that looked more like gorillas to someone who was not used to them.

The Bili Ape Connection

Some researchers have compared the Koolakamba to the Bili Ape, also called the Bondo Mystery Ape, from northern Congo. Bili apes are a group of chimpanzees known for being large and for building nests on the ground like gorillas.

While the Koolakamba is said to live in West Africa and the Bili ape in Central or North Africa, both are examples of big, gorilla-like chimpanzees that make scientists rethink how they classify these animals.

Is Koolakamba Real?

Whether the Koolakamba is real depends on how you define it. If you mean a totally new, undiscovered species of great ape, most scientists today think that is very unlikely. Most experts believe that the old reports and specimens are probably just unusual chimpanzees or mistaken gorillas.

Still, the Koolakamba is “real” in the sense that animals with these unusual, mixed traits have been seen and even photographed in recent years. It is still debated whether these animals are rare genetic throwbacks, a special local group, or a true but rare hybrid.

While the Koolakamba is not as famous as cryptids like Bigfoot, it is an interesting mystery that sits right at the edge of what science knows about apes.
