A curious 5-year-old boy from West Sussex fell 20 feet into a gorilla enclosure at Jersey Zoo in 1986, then 7-foot silverback ‘Jambo’ walked over, sat beside the injured boy and stayed between him and the other gorillas until rescuers arrived

It began with a little boy who simply wanted a better view of the animals kept in the zoo. On August 31, 1986, five-year-old Levan Merritt was visiting Jersey Zoo with his family during a summer holiday. Fascinated by the gorillas, the curious child climbed onto his father's shoulders and leaned over the enclosure wall. Then he fell.

Levan plunged around 20 feet onto the concrete floor of a gorilla enclosure, suffering serious injuries and losing consciousness. But the most extraordinary part of the story was still to come.

Walking toward the unconscious child was Jambo, a massive silverback gorilla standing about seven feet tall and weighing roughly 18 stone (approximately 252 pounds). Horrified visitors watched, expecting the worst. Instead, Jambo did something that would make headlines around the world.

A five-year-old wanted a better view, and then he fell into a gorilla enclosure

The Merritt family from Horsham, West Sussex, had traveled to Jersey for their summer holiday. It was the first day of their trip, and they had visited the zoo to celebrate Levan's younger brother Lloyd's birthday.

Before reaching the gorillas, the children had been enjoying the other animals. In a later interview with the Daily Mail in 2025, Levan recalled finding it amusing when one of the spider monkeys urinated on his father.

But the gorilla enclosure soon captured the children's attention. Levan particularly wanted a closer look at Jambo, the dominant silverback. He climbed onto his father's shoulders and leaned over the wall. “We were just boys being boys, I suppose,” Levan later recalled. “I just wanted to get a better view of them so I was leaning over a bit and then suddenly I went.”

The fall left him with serious injuries, including a fractured skull and a broken arm. He landed unconscious inside an enclosure occupied by several gorillas.

Then the 7-foot silverback walked toward him

For the people watching from above, the situation was terrifying. Jambo approached the motionless five-year-old. The huge silverback was the dominant male of the enclosure, and the sight of such a powerful animal moving toward an injured child caused panic among onlookers.

But Jambo, which means "hello" in the Swahili language, probably justified his name; he did not attack. Instead, videos of the incident show the gorilla gently touching and examining the boy before remaining close to him. He appeared to stand between Levan and the other gorillas in the enclosure.

Watch the video:

For many people, it challenged deeply held perceptions about gorillas as frightening and inherently aggressive animals. Here was one of the world's largest primates sitting beside an unconscious child, and apparently protecting him, like a father.

Jambo appeared to keep the other gorillas away

The tense situation continued as Levan eventually regained consciousness and began to cry. The other gorillas became agitated, but Jambo's behavior remained remarkably calm. He moved the other animals away from the injured child, creating space as rescuers prepared to enter the enclosure.

The rescue itself was another extraordinary moment. Paramedic Brian Fox eventually entered the gorilla enclosure to reach Levan. Speaking to the BBC decades later, Fox played down his role, saying it was simply “part of the job” and that he “got on with it.”

Fox said he made the decision to enter when the boy turned onto his back and lost consciousness. That intervention gave rescuers the opportunity to bring Levan out of the enclosure and get him urgent medical treatment.

The boy survived, but the moment changed how millions saw gorillas

Levan was taken to the hospital and eventually recovered from his injuries. But the footage of what happened inside that enclosure traveled far beyond Jersey. Jambo became internationally famous, and the incident became one of the most remarkable stories involving humans and great apes.

Jambo himself had an unusual place in gorilla history. Born at Basel Zoological Garden in Switzerland on April 17, 1961, he was among the pioneering generation of gorillas born and raised in captivity.

He later fathered numerous offspring and became one of the most famous residents of Jersey Zoo.

Jambo died in 1992 following a rupture of a major artery that caused a chest hemorrhage. His legacy, however, continued. A life-size bronze sculpture was erected in his memory, and Jersey later commemorated him on a special £1 stamp.

Exactly forty years later, the image of Jambo beside the child still resonates

The story remains powerful because almost everything about it seemed to point toward disaster. A five-year-old had fallen 20 feet onto concrete. He was unconscious. He was surrounded by gorillas. And the largest animal in the enclosure was walking directly toward him. Yet Jambo's response became the moment everyone remembered. Levan had climbed onto his father's shoulders because he wanted nothing more complicated than a better view of a gorilla.

Instead, that curiosity led to one of the most astonishing animal encounters ever recorded, and to a scene that, exactally 40 years later, still raises the same question for anyone watching the footage: What made a 400-pound silverback appear to protect a helpless child when the entire world expected him to do the opposite?
