Tonda, the popular orangutan, whose name is 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.
