What Are 5 Facts About Gorillas?

Gorillas are some of the most fascinating creatures on the planet. Known for their strength, intelligence, and close genetic ties to humans, these majestic primates captivate wildlife enthusiasts and scientists alike. Whether you’re planning a gorilla trekking adventure in East Africa or just curious about these incredible animals, learning more about gorillas is both exciting and rewarding.

In this article, we’ll explore five intriguing facts about gorillas that highlight their uniqueness, behavior, and importance to ecosystems.

1. Gorillas Share Nearly 98% of Their DNA With Humans

One of the most surprising facts about gorillas is how closely related they are to humans. Gorillas share approximately 98% of their DNA with us, making them one of our closest relatives, along with chimpanzees and bonobos.

What This Means

• Complex Behavior: Gorillas exhibit behaviors similar to humans, such as using tools, forming strong social bonds, and displaying emotions like grief and joy.
• Communication: Gorillas communicate using a variety of vocalizations, gestures, and facial expressions, much like humans.

Fun Fact: A famous example of gorilla intelligence is Koko, a Western lowland gorilla who learned over 1,000 signs in American Sign Language and could understand spoken English.

Conservation Implications

The genetic similarity between gorillas and humans also means that gorillas are susceptible to many of the same diseases as humans, including respiratory infections. This is why strict health protocols are enforced during gorilla trekking to minimize the risk of disease transmission.

2. There Are Two Main Species of Gorillas

Gorillas are divided into two species, each with two subspecies:

1. Eastern Gorillas
   • Mountain Gorillas: Found in the Virunga Mountains of Rwanda, Uganda, and the Democratic Republic of Congo.
   • Grauer’s Gorillas (Eastern Lowland Gorillas): Inhabiting lowland forests in the Democratic Republic of Congo.
2. Western Gorillas
   • Western Lowland Gorillas: The most numerous gorilla subspecies, found in the rainforests of Central Africa.
   • Cross River Gorillas: A critically endangered subspecies living in a small region along the Nigeria-Cameroon border.

Key Differences Between Species

• Appearance: Eastern gorillas are larger with darker coats, while Western gorillas have lighter, brownish-gray coats.
• Population: Western lowland gorillas are the most abundant, whereas mountain gorillas and Cross River gorillas have critically low populations.

Did You Know? Mountain gorillas were once believed to be extinct in the wild but have made a remarkable comeback due to intense conservation efforts. Today, there are over 1,000 mountain gorillas living in the wild.

3. Gorillas Live in Family Groups Called Troops

Gorillas are highly social animals that live in family groups known as troops. A typical troop consists of:

• A Dominant Silverback: The leader and protector of the group. Silverbacks are mature male gorillas distinguished by a patch of silver hair on their backs.
• Females: Adult females are responsible for raising the young and maintaining the troop’s social structure.
• Juveniles and Infants: Young gorillas stay with their mothers for several years before reaching maturity.

Troop Dynamics

• Leadership: The silverback makes all the decisions, such as when to move, where to forage, and how to respond to threats.
• Communication: Gorillas use vocalizations, chest beating, and body language to communicate within the troop and assert dominance.

Fun Fact: Chest-beating isn’t always a sign of aggression—it can also be used to display confidence or to warn other males to stay away.

Troop Size

Troops typically range from 5 to 30 members, depending on the species and availability of resources. In some cases, solitary silverbacks will roam alone, either after leaving their birth group or while searching for mates.

4. Gorillas Are Gentle Giants, Despite Their Size

While gorillas are the largest primates in the world, they are surprisingly gentle and peaceful animals. Adult males can weigh up to 400 pounds and stand up to 6 feet tall when on two legs, yet their natural behavior is far from aggressive.

Diet and Lifestyle

Gorillas are primarily herbivores, feeding on:

• Leaves
• Fruits
• Bark
• Roots

A gorilla’s diet reflects its peaceful nature, as they spend most of their day foraging and resting. They rarely hunt or show aggressive behavior unless threatened.

When Do Gorillas Show Aggression?

Gorillas only display aggression when they feel their troop or territory is in danger. In such cases, the silverback will defend the group by:

• Standing upright to appear larger.
• Chest-beating and roaring to intimidate threats.
• Charging as a last resort.

Did You Know? Gorillas’ intimidating displays often deter predators without the need for actual combat.

5. Gorillas Play a Vital Role in Their Ecosystems

Gorillas are known as ecosystem engineers because of the significant role they play in maintaining the health of their habitats.

Seed Dispersers

As gorillas move through the forest and consume fruits, they help disperse seeds through their droppings, promoting forest regeneration.

Habitat Maintenance

By feeding on plants, gorillas help control vegetation growth, ensuring that certain plant species don’t dominate and disrupt the ecosystem’s balance.

Fun Fact: The survival of many tree species depends on gorillas for seed dispersal, making them essential to biodiversity in their habitats.

Conservation Challenges

Despite their importance, gorillas face numerous threats, including:

• Habitat loss due to deforestation and agriculture.
• Poaching for bushmeat or the illegal wildlife trade.
• Disease outbreaks, particularly those transmitted by humans.

Conservation organizations and governments are working to protect gorillas through anti-poaching patrols, habitat restoration, and ecotourism initiatives.

Why Protecting Gorillas Matters

Gorillas are not just fascinating creatures; they are crucial to the health of their ecosystems and serve as symbols of conservation success. By protecting gorillas, we also safeguard countless other species that share their habitats, ensuring the long-term sustainability of these unique ecosystems.

Gorillas are extraordinary animals that capture the imagination with their intelligence, social behavior, and vital ecological role. From their genetic similarity to humans to their peaceful nature, gorillas continue to teach us about the wonders of the natural world.

Whether you’re planning to see mountain gorillas in Uganda or Rwanda or simply want to learn more about these gentle giants, understanding their importance and challenges is the first step in supporting their conservation. Gorillas remind us of the beauty and complexity of life on Earth—and our responsibility to protect it.
