Few viral stories have stirred as much emotion online as that of Punch, a seven-month-old Japanese macaque from the Ichikawa Zoo in Japan. Born last July, Punch became an international sensation after footage of him being rejected by his mother and tormented by older monkeys began circulating widely. What made the videos even more affecting was the sight of the tiny primate finding solace in a stuffed orangutan toy, clutching it tightly as the world watched with a mixture of heartbreak and fascination. The clips spread rapidly across social media, prompting millions of people to ask the same question, namely why would a mother abandon her own offspring?
Primatology experts say that while maternal rejection in monkeys is uncommon, it is not unheard of under specific circumstances. Alison Behie, a primatology specialist from the Australian National University, explained that factors such as “age, health and inexperience” can all contribute to a mother walking away from her baby. In Punch’s case, his mother was a first-time parent, which Behie pointed to as a likely contributor to the situation. She also noted that Punch was born during a heat wave, adding yet another layer of stress to an already fragile dynamic.
“In Punch’s case, his mother was a first-time mother, which suggests inexperience,” Behie said. “Keepers also report that Punch was born during a heat wave, which would have been a very stressful environment. In conditions where survival is threatened by external stress, mothers may prioritize their own health and future reproduction rather than continuing to care for an infant whose health may be compromised by those environmental conditions.” This perspective reframes what many viewers interpreted as cruelty into something far more rooted in biological survival instinct, even if the outcome remains deeply sad.

After Punch was left on his own, zookeepers at Ichikawa worked to find him a substitute for the physical comfort a mother would normally provide. Keeper Kosuke Shikano explained that staff first tried rolled towels of various thicknesses before settling on the plush toy. “Young Japanese macaques cling to their mother’s body immediately after birth to build muscle strength. By holding onto something, they also gain a sense of security. However, since he was abandoned, Punch had nothing to cling to,” Shikano said. “We thought that a toy resembling a monkey might later help Punch reintegrate into the group.” Behie added that the stuffed animal likely functions as an attachment figure, particularly given that at six months old, Punch would ordinarily still be nursing.
Many viewers were also disturbed by footage showing older macaques harassing and dragging Punch around the enclosure. However, Behie was careful to clarify that this behavior is not abuse in the scientific sense. She described it as “not bullying or any abnormal behavior, but normal social interaction,” rooted in the strict maternal-line hierarchies that define Japanese macaque society, where higher-ranking families assert dominance over lower-ranking ones. Even if Punch had remained with his mother, he would likely still face such interactions. The deeper concern, according to Behie, is that without maternal guidance, Punch may not properly develop the submissive responses needed to navigate group life as an adult, which could create lasting challenges for his social integration down the line.
The story has also prompted experts to speak out about the broader implications of Punch’s fame. Carla Litchfield, a conservation psychologist from the University of Adelaide, praised the way the story has connected people emotionally to wildlife, but issued a pointed warning. “This Punch story highlights the impacts of habitat loss, climate change, animal welfare in zoos, and the power of social media to connect people with animals,” she said. “However, we hope that the millions of social media likes and media attention won’t exacerbate the problem of illegal trade in infant monkeys as exotic pets, because everyone thinks small monkeys are cute and would make great pets.” She went on to emphasize that monkeys grow up quickly, noting that Punch will be fully grown in about four years, at which point people no longer see them as charming or manageable. “Monkeys belong with other monkeys. They are social beings and need to be with their own kind to develop mentally and physically,” Litchfield concluded.
The surge of global interest has led the Ichikawa Zoo to strengthen barriers around Punch’s enclosure and ask visitors to remain quiet, refrain from using ladders or photography tripods, and limit prolonged observation sessions. Punch is not the first zoo animal to capture worldwide attention in recent years. Moo Deng, a young pygmy hippopotamus in Thailand, became a global favorite in 2024 thanks to her feisty personality and undeniable charisma.
Japanese macaques, also known as snow monkeys, are the most northerly-living nonhuman primates in the world and are native to Japan. They are highly intelligent, adaptable animals known for behaviors such as washing food in water and soaking in hot springs during cold weather. In the wild, Japanese macaque society is organized around matrilineal groups, meaning that a young monkey’s social rank is directly tied to its mother’s status within the troop. Infants typically remain in close physical contact with their mothers for the first year of life, nursing and learning essential social behaviors. Without that foundation, reintegration into a group can be a long and difficult process, as Punch’s situation so vividly illustrates.
