An affectionate moment or something more sinister?
The photo appears to show a bonobos embracing a small ferret like a dear pet. But instead, the ferret monkey may have taken the pup out to dinner after killing his mother.
But this would be unusual – bonobos mainly eat fruit and only occasionally hunt.
Christian Ziegler in the Democratic Republic of the Congo has photographed the interesting behavior.
His remarkable photo was selected as the Highly Commended in the 58th Natural History Museum’s Wildlife Photographer of the Year (WPY) competition.
The shortlist was revealed on Thursday, and the winners will be announced publicly at London’s Natural History Museum (NHM) in October.
Christian had been tracking a group of bonobos “chest deep through the flooded forest” in Salonga National Park for several days when he spotted the young man holding a baby mongoose in his hand.
He told BBC News: “I was surprised to see how the ferret carried with such care. I immediately started following him and documenting him.”
He said the monkey held and petted the little ferret for more than an hour.
But he might have been planning to eat it. When bonobos hunt their prey, they don’t kill it right away, but instead start eating when it’s still alive, according to Dr. Barbara Froth, director of the LuiKotale Bonobo Project that has been monitoring these animals for more than 20 years.
But sometimes, if the dinner is too big and the monkey is full, he will treat the remaining live prey as pets. Usually, these animals are eaten later.
Dr. Froth thinks this may have been what was happening in the photo.
She highlighted that bonobos are known for their gentle, sympathetic and peaceful nature.
“We know from captivity that bonobos care about people other than their own sex,” she says. In the wild, she adds, bonobos are unlikely to take care of other species as a long-term pet.
But it does not rule out the idea that monkeys keep other animals as accessories to attract the interest of other members of the group and thus increase their prestige.
In the end, this mongoose had a happy ending – the bonobos eventually released his “pet”, who then escaped unharmed.
The mystery behind the photo is part of its appeal to the Natural History Museum competition judges.
Dr. Natalie Cooper, a senior researcher at the Natural History Museum, narrowed down nearly 40,000 entries across 20 categories with her fellow judges. “We’re looking for really cool pictures from a technical point of view — the ones you see once and wake up in the morning still thinking about,” she says.
WPY has become one of the most prestigious competitions of its kind. Entries were received from 93 countries for this year’s event.
Category and grand prize winners will be announced at the Natural History Museum Gala on October 11th. The museum will then open its annual exhibition of the best photographs on October 14.
The right look for Richard Robinson, New Zealand
In the portrait of Richard Robinson, he and his camera become the subject of a fascination for this young southern right whale. The confrontation lasted 30 minutes, with the whale spinning around, swimming, and then back to take another look.
Whales were hunted to the brink of extinction in the 19th and 20th centuries, but the population of southern right whales, known as “tohorā” in Maori, is now recovering after hunting has been banned.

Underwater Wonderland – Tina Tormanen, Finland
A school of curious chick met photographer Tina Tormannen on a snorkeling in the lake in Bosseau, Lapland.
Excessive cloud-like algae growth, as a result of climate change and rising water temperatures, can cause a problem for aquatic life when it uses up oxygen and blocks out sunlight.
Lost Floods by Jasper Dost, Zambia
Dutch photographer Jasper Dost captured Lubinda Lubinda, Zambezi River Authority station manager, in front of his new home (right) that didn’t need to be built as high as his last home due to low water levels. Climate change and deforestation have caused the Zambezi Flood Plain to experience more droughts.
Dr. Natalie Cooper discussed the photo, saying: “We can talk about climate change until we turn blue in the face, but until you see the reality of the problem on the screen in front of you, it is difficult to connect with this topic.”
Polar frame from Dmitriy Koch, Russia
More than 20 polar bears have taken over Kolyushin Island in Russia, which has been abandoned since 1992, in search of food. As climate change reduces sea ice, polar bears are finding it difficult to hunt, forcing them closer to human settlements to hunt. A low-noise drone was used to capture the stunning photo.

Treefrog Pool Party by Brandon Joel, Costa Rica
Here, the photographer wades into chest-high waters to capture the frenzy of breeding at dawn. You can almost hear the mating calls of male tree frogs rolling around while the females lay their eggs in palm fronds – about 200 at a time – which later drop into the water below like tadpoles.

Snow Deer – Joshua Cox, 8 years old, UK
Joshua is now eight years old but was only six when he snapped this majestic stag during heavy snowfall in Richmond Park, London. He started using toy camera when he was just a toddler and developed into a compact camera shortly before this photo was taken. “It looked like it was snowing,” Joshua said.
