Endangered Species’ Genetic Legacy to Be Preserved After Death at Drusillas Park
A rare bearcat, also known as a binturong, that recently passed away at a UK zoo will be cryogenically frozen in an effort to preserve its genetic material for future research and conservation efforts. The binturong, named Penh, lived at Drusillas Park in East Sussex and died at the age of 18 on July 31. Penh was one of only three of his species housed in European zoos and had spent 14 years in England. The decision to freeze his body underscores the ongoing commitment to studying and conserving this endangered species.
The importance of Penh’s preservation
As binturongs face the looming threat of extinction in their native Southeast Asian habitats due to rampant deforestation, conservationists are increasingly relying on wildlife sanctuaries to help preserve the species. By freezing Penh’s body, scientists aim to utilize his genetic material for research and possibly to aid in breeding programs, thereby contributing to the survival of the species.
The staff at Drusillas Park expressed their sorrow at the loss of Penh, who was a beloved member of the zoo’s animal family. “A true gentleman, lover of tomatoes, and a sweet and gentle soul, he will be missed by his keepers and our visitors. But Penh’s legacy will live on,” the park shared in a heartfelt statement on Instagram.
Cryogenic preservation for conservation
Penh’s body has been entrusted to the animal charity Nature’s SAFE, which specializes in cryogenic preservation. The organization will freeze his genetic material, including sperm and skin cells, with the hope of potentially using it in the future to breed more binturongs. This effort aims to support the long-term survival of the species.
Headkeeper Gemma, who personally delivered Penh’s cell tissue to Nature’s SAFE, reflected on the experience: “It felt very bittersweet. I’ve worked with Penh for over a decade, so although I felt sad, it was also a positive feeling knowing it was not necessarily the end for him.” The team at Nature’s SAFE confirmed the viability of Penh’s sperm sample shortly after testing, marking an important step in the preservation process.
What is a bearcat?
The bearcat, or binturong (Arctictis binturong), is a unique and fascinating species native to Southeast Asia. Despite its name, it is neither a bear nor a cat but belongs to the Viverrid family, which includes civets and genets. Bearcats are relatively large, with adults growing up to 6 feet in length and weighing between 20 and 40 pounds. They have a distinctive appearance, characterized by a mix of grey, white, and black fur, and a long, bushy tail.
Bearcats are typically found in the forests and grasslands of countries like Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Thailand, and Vietnam. They are solitary, nocturnal creatures, known for their excellent climbing abilities and preference for resting in trees during the day. Their diet is omnivorous, consisting of fruits, leaves, insects, and small animals.
Conservation status
The binturong is currently listed as Vulnerable on the IUCN Red List due to habitat loss, hunting, and human-wildlife conflict. The preservation of Penh’s genetic material represents a vital effort to ensure that this unique species continues to thrive despite the challenges it faces in the wild.
