USA - On 9 December a toddler peered through thick glass as
African penguin Tess dove into her pool at the
Pueblo Zoo. It was the penguin’s first swim since
Colorado State University (CSU) veterinarians used specialised radiation to treat an aggressive form of skin cancer on her face.
At 40 years old, Tess is the oldest known African penguin, the matriarch of a dying species and a beloved member of the penguin exhibit at the Pueblo Zoo in southern Colorado. For the veterinarians who treated Tess for skin cancer in early December, she is a beacon on a planet with a dwindling variety of creatures.
“Some people would ask, ‘Why are you putting all of these resources into an individual animal?’ But, if this individual animal can tell a story that helps globally with the African penguin, then it’s all worth it,” said Dr. Matthew Johnston, a CSU veterinarian in Avian, Exotic and Zoological Medicine at the James L. Voss Veterinary Teaching Hospital.
