The Twitter account of an Ohio zoo targeted by online critics and trolls over the shooting of a gorilla has been taken down.

The Cincinnati Zoo has said it's not amused by the memes, online petitions and signs about Harambe (huh-RAHM'-beh), a 17-year-old great ape killed in May by a special zoo response team after a 3-year-old boy got into his enclosure. Harambe has been mourned, memorialized and satirized nearly continuously since his death.

Those seeking the zoo's Twitter site Tuesday got a message saying, "Sorry, that page doesn't exist!"

Zoo director Thane Maynard recently told The Associated Press by email that the zoo family is "still healing."

A request for comment was sent Tuesday to a zoo spokeswoman.
