Kirk, a member of the Dallas Zoo’s chimpanzee unit, died of heart disease on Friday, the zoo said.
The 31-year-old chimpanzee held his breath at the end of the day shortly before the primate zoologist turned around. According to the zoo, lifesaving measures were unsuccessful.
Autopsy showed that the chimpanzee suffered from heart disease, the leading cause of death in great apes, but the zoo showed signs of heart-related illness and distress in the weeks leading up to his death. Said it wasn’t.
Kirk came to the zoo in March 2018 with his mother Margaret.
The zoo said in a social media post that Kirk was “a sweet chimpanzee who loves to eat carrots and rush around his habitat.”
His death occurs months after Missy, the oldest chimpanzee at the zoo, died in February at the age of 56.
