Atlantic harbor seal Yellow was euthanized a week before what would have been her fortieth birthday. She had been declining in health as of late.
Mourning the Loss of Beloved Atlantic Harbor Seal | The Buttonwood Park Zoo
"Yellow, as one of BPZOO’s oldest residents, and the oldest female Atlantic harbor seal in an institution accredited by the Association of Zoos and Aquariums (AZA) was under careful monitoring and care for many age-related illnesses. Recently, animal care staff noticed a reduction in her appetite, and increasing troublesome neurological signs, such as lethargy, decreased mobility, and, finally, seizures.
After a variety of diagnostic tests, including bloodwork, a whole-body CT scan and infectious disease testing it became clear that her condition was continuing to deteriorate. Due to advanced age, poor prognosis, and a major decline in her quality of life, Zoo leadership, animal care, and veterinary teams made the difficult decision to humanely euthanize her. She passed away surrounded by her animal care team. A necropsy has been performed and biopsies were submitted with results pending."
"Yellow gave birth to Blue, her sole living offspring in 2003 and together they built strong relationships with their caretakers. These strong connections allowed for hands-on vet exams and close monitoring of their health, contributing to her longevity. Yellow knew more than 25 trained behaviors, including stationing on a scale, allowing keepers to brush her teeth, place drops in her eyes and even presenting herself for x-rays, vaccines, and blood draws."
