When people think of gorillas, they often picture powerful, majestic creatures roaming the dense forests of Africa. But have you ever wondered what fuels these great apes? Despite their size and strength, gorillas are surprisingly gentle and primarily herbivorous. In the wild, they follow a rich, plant-based diet that reflects the lush environments they inhabit.
Let’s take a closer look at what gorillas eat in the wild—and how their diets help keep them healthy, strong, and well adapted to their forest homes.
The Basics: Gorillas Are Mostly Vegetarians
Gorillas are herbivores, which means their diet is mostly made up of plants, fruits, leaves, and stems. However, their exact diet depends on the species of gorilla and the habitat in which they live.
There are two main types of gorillas found in the wild:
- Eastern gorillas, which include mountain gorillas and eastern lowland gorillas
- Western gorillas, including western lowland gorillas
Let’s explore their eating habits further.
1. Mountain Gorillas – Leaf-Lovers of the Highlands
Mountain gorillas, like those found in Bwindi Impenetrable Forest and the Virunga Mountains, live at high altitudes where fruit is less abundant. Their diet is dominated by foliage, and they consume:
- Leaves and stems (e.g., wild celery, bamboo shoots, thistles)
- Roots
- Bark
- Pith (soft inner plant tissue)
- Occasionally insects (like ants or termites), but this is rare and forms less than 1% of their diet
Mountain gorillas can eat up to 30 kilograms (66 pounds) of vegetation per day to sustain their massive bodies.
2. Lowland Gorillas – Fruit-Loving Foragers
Eastern and western lowland gorillas live in areas where fruit is more readily available, and their diets reflect that. They enjoy:
- Fruits (up to 70% of their diet during peak fruit seasons)
- Seeds
- Leaves and stems
- Occasionally termites and ants
Western lowland gorillas, in particular, are known to travel longer distances to find fruiting trees, displaying impressive memory and navigational skills.
Gorillas and Water: They Rarely Drink!
One surprising fact is that gorillas rarely drink water. Their diet provides all the hydration they need:
- Leaves and stems have high water content
- Morning dew on plants also helps keep them hydrated
They’ll only seek out water sources during extreme dry conditions or if their regular food becomes scarce.
Foraging Behaviour: Gorillas Are Smart Eaters
Gorillas don’t just grab the nearest plant and chew—it’s more refined than that. They:
- Select specific plants and parts of plants
- Strip bark with their teeth
- Use their hands skillfully to peel leaves, crack stems, or clean food
- Spend about 6 to 8 hours per day feeding
The rest of their day is spent resting, grooming, playing, and traveling to new feeding areas.
How Their Diet Supports the Ecosystem
Gorillas are not just eaters—they’re ecological gardeners. By:
- Dispersing seeds through their droppings
- Trimming vegetation as they feed
- Helping forests regenerate naturally
Their feeding behaviour plays a crucial role in maintaining the balance and biodiversity of tropical forests.
Conclusion: Eating Green, Living Strong
Gorillas are the ultimate example of strength built on a plant-powered diet. Whether munching bamboo shoots in the misty mountains or foraging for fruit in dense rainforests, these gentle giants eat a varied, fiber-rich diet that supports their health and the environment around them.
Next time you see a gorilla on safari or in a documentary, you’ll know: behind that powerful frame is a quiet, thoughtful vegetarian—living in harmony with the forest it calls home.
