For as long as humans have existed, we’ve been fascinated by the animal kingdom, trying to understand and connect with other species. While we’ve made progress with animals like dogs, who can follow simple commands, and are even working on translating whale language, truly understanding animals’ thoughts and feelings remains a challenge.
One of the closest connections we’ve made is with Coco, a Western lowland gorilla. Coco became famous for her ability to communicate using American Sign Language. Born in 1971 at the San Francisco Zoo, Coco was rejected by her mother and became ill. Francine Patterson, a graduate student from Stanford University, took Coco in and taught her sign language as part of her studies. Over the years, Coco learned over a thousand words, could express her needs, and even showed emotions like grief.
Gorillas aren’t our closest relatives, but we share about 98% of our DNA with them. They have large, complex brains and are incredibly intelligent. However, if you saw a gorilla in the wild, you’d probably first notice their size and strength. Gorillas are the largest of the great apes, living in Equatorial Africa, with two main species: eastern and western gorillas. They live in family groups, usually with five to ten members, but sometimes as few as two or as many as fifty.
Gorillas show a big difference in size between males and females, known as sexual dimorphism. Male gorillas, called silverbacks because of the gray or silver hair on their backs, can weigh up to 180 kilograms. They are incredibly strong, able to lift over 450 kilograms, which is two and a half times their body weight. Some of the strongest gorillas can lift up to 815 kilograms, much more than the human deadlift record of 501 kilograms. Their strength comes from their dense bones, which are more resistant to fractures.
Gorillas are mostly herbivores, eating plants like stems, bamboo shoots, and fruits, with only a small amount of insects. Their digestive system is specially adapted to break down cellulose, a tough part of plants. They have a longer gut to help them get nutrients from their fibrous diet.
Gorillas can be aggressive, but serious fights are rare in stable groups. They are social and work together, with western lowland gorillas traveling to find food. They start their day at dawn, foraging in the forest, and at night, each gorilla builds a nest on the ground to sleep.
In the wild, gorillas don’t often use tools, but they have been seen using sticks to test water depth or balance while foraging. In captivity, they show more tool use, learning from each other, especially from their mothers. Gorilla social structures are complex, with strong family bonds. Dominant males often take on caring roles, which might influence female mate choices. Gorillas communicate through facial expressions, gestures, and sounds.
Coco’s ability to learn sign language was groundbreaking. She learned signs at a rate similar to a human child and used over 1,100 signs in her life. Coco could express her feelings and needs, showing empathy and understanding. Her legacy continues as researchers study how different species communicate, aiming to better understand gorillas and improve their lives both in captivity and in the wild.
Studying gorilla communication helps us learn more about their emotional and intellectual abilities. As we discover more about their language, we may gain even deeper insights into their world, bringing us closer to understanding these incredible creatures.
Imagine you are a researcher like Francine Patterson. Create a mini sign language workshop where you and your classmates learn some basic signs that Coco the gorilla used. Practice these signs with each other and discuss how this form of communication might help bridge the gap between humans and gorillas.
Explore the concept of strength by comparing your own abilities to those of a gorilla. Create a chart that shows the weight a gorilla can lift compared to the human deadlift record. Then, try a safe strength challenge, like holding a plank position, and see how long you can last. Discuss the differences in strength and what factors contribute to a gorilla’s incredible power.
Research the diet of a gorilla and compare it to your own. Create a meal plan for a day that includes the types of food a gorilla would eat. Discuss how their digestive system is adapted to their diet and what nutrients they get from their food. Consider how their diet supports their lifestyle and strength.
In groups, role-play a day in the life of a gorilla family. Assign roles such as the silverback, females, and young gorillas. Act out their daily activities, such as foraging and building nests. Discuss the social structure and how each member contributes to the group’s survival and well-being.
Investigate the tools gorillas use in the wild and in captivity. Create a simple tool using materials available in your classroom and demonstrate how it could be used for a task. Discuss how tool use reflects intelligence and problem-solving abilities in gorillas, and compare it to human tool use.

For as long as humans have existed, there has been a barrier between us and the rest of the animal kingdom—a barrier of understanding and connection. We’ve made some progress with animals like dogs, who can understand simple commands, and there is ongoing research to translate whale language. However, when it comes to conversing with animals about thoughts and feelings, we haven’t quite bridged that divide.
The closest we may have come is with Coco, the Western lowland gorilla, who became an ambassador for her critically endangered species. Coco was renowned for her love of cats, her friendship with Robin Williams, and her ability to communicate through American Sign Language. Born at the San Francisco Zoo in 1971, Coco was rejected by her mother and became ill. Stanford University graduate student Francine Patterson took her in and taught her sign language as part of her doctoral work in developmental psychology. Over decades, Coco developed a vocabulary of over a thousand words, could reason about the world, communicate her needs, and even grieve.
While gorillas aren’t our closest living relatives, we share about 98% of our DNA with them. Despite having larger and more complex brains, gorillas are incredibly intelligent. However, if you were to encounter a gorilla in the wild, your first thought might not be about their intelligence, but rather about their size and strength. Gorillas are the largest of the great apes, living in Equatorial Africa, with two species: eastern and western gorillas. They live in family groups, usually consisting of five to ten members, but sometimes as few as two or as many as fifty.
Gorillas exhibit significant sexual dimorphism, with smaller females and much larger males, known as silverbacks due to the gray or silver hair on their backs. An average silverback can weigh up to 180 kilograms and can easily deadlift over 450 kilograms—two and a half times their body weight. In comparison, the strongest gorillas can lift up to 815 kilograms, while the human deadlift record is 501 kilograms. Despite similar muscle mass to weight ratios, gorillas are much stronger due to denser bones that are more resistant to fractures.
Gorillas are primarily herbivores, consuming a diet mostly of plant matter, such as stems, bamboo shoots, and fruits, with only a limited intake of insects. Their digestive system is adapted to break down cellulose, which is a fibrous component of plants. They have a longer gut, allowing them to extract nutrients from their fibrous diet.
When gorillas do engage in aggression, it can be severe, with fights sometimes leading to serious injuries. Fortunately, extreme aggression is rare in stable gorilla groups, which are social and collaborative. Western lowland gorillas travel to find food, beginning their day at dawn and foraging throughout the forest. At night, each gorilla builds a nest on the ground to sleep, demonstrating a level of skill in this behavior.
While tool use is rare among wild gorillas, there have been observations of them using sticks to test water depth or balance themselves while foraging. In captivity, gorillas have shown more extensive tool use, learning from one another, especially from their mothers.
Gorilla social structures are complex, with strong bonds formed within family groups. Interestingly, dominant males often take on caring roles, which may influence female mate selection. Communication among gorillas is multifaceted, involving facial expressions, gestures, and vocalizations.
Coco’s ability to learn American Sign Language was groundbreaking. She learned signs at a rate comparable to a human child, using over 1,100 signs throughout her life. Coco communicated her feelings and needs, revealing a level of empathy and understanding. Her legacy continues as researchers study interspecies communication to better understand gorillas and improve their conditions in captivity and in the wild.
In conclusion, the study of gorilla communication opens up new avenues for understanding their emotional and intellectual capabilities. As we learn more about their language, we may discover even richer insights into their world.
