It has two subspecies: the Western Lowland Gorilla (Gorilla gorilla gorilla) and the Cross River Gorilla (Gorilla gorilla diehli). Among these, the Western Lowland Gorilla is generally smaller in size compared to the other gorilla species and subspecies. Adult male Western Lowland Gorillas, known as silverbacks, typically weigh between 300 to 400 pounds (136 to 181 kilograms). The Cross River Gorilla, being a subspecies of the Western Gorilla, is also relatively small in size compared to its counterparts in the Eastern Gorilla species.

What is the lifespan of Cross River Gorilla?

The lifespan of Cross River Gorillas (Gorilla gorilla diehli) in the wild is estimated to be around 35 to 40 years. However, these estimates can vary, and individual lifespans may be influenced by factors such as habitat conditions, availability of food, and threats from human activities.

In captivity, gorillas may have the potential to live longer than their wild counterparts due to the absence of certain threats and access to veterinary care. As with many wild animals, lifespan in the wild is influenced by a range of ecological factors, while those in captivity may have more controlled and supportive conditions.

What do Cross River Gorilla Eat?

Cross River Gorillas (Gorilla gorilla diehli) are primarily herbivores, and their diet consists mainly of plant matter. They are folivores, frugivores, and to a lesser extent, they may consume some insects. Their diet includes:

1. Leaves and Vegetation

Cross River Gorillas feed on a variety of leaves, stems, and other vegetation. They are known to consume a wide range of plant species found in their habitat.

2. Fruits

Fruits are an important part of their diet when available. Cross River Gorillas consume fruits from various plant species, providing them with essential nutrients.

3. Bark and Shoots

Gorillas may also eat the bark of certain trees and young shoots. This behaviour is more common during periods when other food sources are scarce.

4. Insects

While the main bulk of their diet is plant-based, Cross River Gorillas may occasionally eat insects, such as ants and termites.

Their diet can vary seasonally based on the availability of different food sources. Cross River Gorillas are adapted to their specific habitat in the montane and lowland forests of Cameroon and Nigeria, where they forage for a diverse array of plant resources.

How Do Cross River Gorilla Raise (Nurture) Their Offspring?

Cross River Gorillas, like other gorilla species, exhibit strong social bonds and a complex social structure. The nurturing and upbringing of their offspring involve several key aspects:

1. Family Structure

Gorillas live in family groups led by a dominant silverback or adult male. The familial unit generally comprises adult females, their young, and potentially additional subordinate males.

2. Role of the Silverback

The silverback or adult male plays a crucial role in the protection and guidance of the group, including the young ones. He provides protection against potential threats and helps maintain order within the group.

3. Protection and Care

Adult females, including the mother, actively participate in caring for the young gorillas. They are protective, and the group as a whole contributes to the safety and well-being of the infants.

4. Social Learning

Young gorillas learn essential life skills through observation and interaction with other members of the group. They observe the behaviour of adults, including feeding habits, social interactions, and communication.

5. Weaning

The weaning process involves transitioning the offspring from solely relying on their mother's milk to consuming solid food. This is a gradual process, and the mother's guidance plays a role in teaching the young gorilla what to eat.

6. Adolescence and Independence

As gorillas mature, they go through stages of adolescence, during which they become more independent. While they may still stay within the family group, they gradually develop their own identities.
