The Nigeria-Cameroon Chimpanzee: A Fascinating Primate in Danger

   Chimpanzees are one of the most iconic and beloved primate species, known for their high intelligence, complex social behaviors, and striking physical appearance. However, many people may not be aware of the unique and endangered subspecies known as the Nigeria-Cameroon chimpanzee. This fascinating primate is found only in a narrow range of forested habitats in West and Central Africa, and its population is threatened by habitat loss, poaching, and other human activities. In this article, we will explore the scientific name and classification, history, physical description, social structure, behavior, reproduction, diet, threats, and relationship with humans of the Nigeria-Cameroon chimpanzee. We will also reveal some incredible and fun facts about this amazing primate.

Scientific Name and Classification:

  The Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti) is a subspecies of the common chimpanzee (Pan troglodytes), which belongs to the family Hominidae and the order Primates. There are four recognized subspecies of the common chimpanzee, including the Nigeria-Cameroon chimpanzee, the Western chimpanzee (Pan troglodytes verus), the Central chimpanzee (Pan troglodytes troglodytes), and the Eastern chimpanzee (Pan troglodytes schweinfurthii).

Type:

  The Nigeria-Cameroon chimpanzee is a primate species that belongs to the great ape family. It is one of the largest and most robust chimpanzee subspecies, with a muscular body, long arms, and powerful jaws. It is known for its unique vocalizations, complex social behavior, and tool-making abilities.

History:

  The Nigeria-Cameroon chimpanzee was first described in 1906 by the American naturalist Joel Asaph Allen, who named it after the British zoologist Daniel Giraud Elliot. However, it was not recognized as a distinct subspecies until 1933, when the British primatologist Colin Groves studied the geographic and morphological variation of chimpanzees across Africa.

Evolution and Origins:

  Chimpanzees are believed to have diverged from the human lineage about 6 million years ago, and they share more than 98% of their DNA with humans. The Nigeria-Cameroon chimpanzee is thought to have evolved as a separate subspecies about 500,000 years ago, when a population of common chimpanzees became isolated in the forested region between the Cross and Sanaga Rivers in Nigeria and Cameroon.

Physical Description:

  The Nigeria-Cameroon chimpanzee is one of the largest chimpanzee subspecies, with males weighing up to 70 kg (154 lb) and females weighing up to 50 kg (110 lb). It has a thick, dark brown or black coat, with a bare face and hands, and a protruding brow ridge. Its long arms are adapted for climbing and swinging through the trees, and its opposable thumbs and toes allow it to grasp and manipulate objects with great dexterity.

Social Structure:

  The Nigeria-Cameroon chimpanzee lives in complex and dynamic social groups, typically consisting of 20-80 individuals led by a dominant male. Females stay with their natal group for life, while males usually disperse to other groups at adolescence. Chimpanzees communicate with each other through a variety of vocalizations, gestures, and facial expressions, and they engage in a wide range of social behaviors, such as grooming, playing, hunting, and sharing food.

Anatomy and Appearance:

  The Nigeria-Cameroon chimpanzee has a muscular body, with a broad chest, strong arms, and powerful legs. Its skull is large and robust, with a protruding brow ridge and a wide, flattened nose. Its teeth are also large and strong, adapted for crushing and grinding tough plant material and occasionally hunting small animals. Its coat is thick and coarse, providing insulation and protection from parasites and the elements. Chimpanzees have highly expressive faces, with a range of emotions conveyed through subtle changes in eyebrow, mouth, and eye movements.

Distribution and Habitat:

  The Nigeria-Cameroon chimpanzee is found only in a small and fragmented range of forested habitats in Nigeria and Cameroon, between the Cross and Sanaga Rivers. Its habitat includes dense tropical rainforests, gallery forests, and wooded savannahs. However, much of its range has been destroyed or degraded by human activities, such as logging, farming, and mining.

Population – How Many Are Left?:

  The Nigeria-Cameroon chimpanzee is listed as Endangered on the IUCN Red List of Threatened Species, with an estimated population of only 6,000-9,000 individuals remaining in the wild. This represents a decline of at least 80% over the past three generations, primarily due to habitat loss and hunting for bushmeat and the pet trade.

Size:

  The Nigeria-Cameroon chimpanzee is one of the largest chimpanzee subspecies, with males measuring up to 1.7 m (5.6 ft) in height and females measuring up to 1.3 m (4.3 ft) in height. Its arms are longer than its legs, allowing it to brachiate through the forest canopy with ease.

Weight:

  The Nigeria-Cameroon chimpanzee is a heavy and muscular primate, with males weighing up to 70 kg (154 lb) and females weighing up to 50 kg (110 lb). However, weight can vary depending on factors such as age, sex, and diet.

Behavior and Lifestyle:

  The Nigeria-Cameroon chimpanzee is a highly social and intelligent primate, with a wide range of behaviors and vocalizations. It communicates with other chimpanzees through a variety of calls, grunts, screams, and gestures, and is capable of using tools to access food, such as using sticks to extract termites from a mound. Chimpanzees also engage in a range of social behaviors, such as grooming, playing, and hunting in groups. They are known to use facial expressions to convey emotions, such as fear, aggression, and happiness.

Reproduction, Babies, and Lifespan:

  The Nigeria-Cameroon chimpanzee reaches sexual maturity at around 12-15 years of age, and females typically give birth to a single offspring every 5-6 years. The gestation period lasts about 230 days, and newborn chimpanzees are dependent on their mothers for milk and protection for several years. The lifespan of the Nigeria-Cameroon chimpanzee is estimated to be around 45-50 years in the wild.

Diet and Prey:

  The Nigeria-Cameroon chimpanzee is primarily herbivorous, feeding on a wide variety of fruits, leaves, flowers, and bark. However, it is also known to hunt and eat small animals, such as monkeys, birds, and rodents, as well as termites and other insects. Chimpanzees have been observed using tools to access food, such as using sticks to extract termites from a mound or using stones to crack open nuts.

Predators and Threats:

  The main threats to the Nigeria-Cameroon chimpanzee are habitat loss and degradation, as well as hunting for bushmeat and the pet trade. Chimpanzees are also vulnerable to diseases, such as Ebola virus, which can decimate entire populations. The Nigeria-Cameroon chimpanzee has no natural predators, but it may occasionally be preyed upon by leopards and other large carnivores.

Relationship with Humans:

  The Nigeria-Cameroon chimpanzee has a complex relationship with humans. While it is revered and protected in some cultures, such as among some indigenous communities in Cameroon, it is also hunted for bushmeat and captured for the pet trade. Habitat destruction and fragmentation also threaten the survival of the species. Conservation efforts, such as habitat restoration and anti-poaching patrols, are crucial for the protection of the Nigeria-Cameroon chimpanzee.
