Tonda, short for Tondaleyo, died in her sleep at the age of 50. Tonda had represented the oldest registered orangutan in captivity in the United States.
Tonda, along with a male kitten named T.K., had earned a modicum of fame after being named the second-best animal odd couple by Animal Planet. The pair were also the subject of a book, Tonda and TK: Friends.
