It sounds like something from a wildlife fairytale — but photographs captured in Tanzania appear to show something scientists had never documented in the wild before.

A lioness named Nosikitok was photographed nursing a young leopard cub in the Serengeti, creating an astonishing interspecies encounter between two animals that would normally be fierce competitors.
The images were witnessed by a guest staying at Ndutu Lodge in Tanzania’s Ngorongoro Conservation Area and were later shared with conservationists from KopeLion, a partner of global wild-cat organization Panthera.
For big-cat experts, the scene was extraordinary.

Panthera’s Luke Hunter described the event as unprecedented, noting that while interspecies suckling has been observed in captivity, there had been no previous record of a wild large carnivore nursing a different species.
But behind the heartwarming images were troubling unanswered questions.
Researchers did not know where the leopard cub’s mother was, while Nosikitok was spending time away from her own three cubs. Conservationists were concerned about what might have happened to them, although their fate was not confirmed.

There was another danger, too. Even if Nosikitok continued caring for the leopard, scientists warned that introducing an unfamiliar cub into a lion pride could put the youngster at serious risk.
For one remarkable moment, however, the usual boundaries between predator and prey seemed to disappear — replaced by an extraordinary act of maternal care.
