Tatu at the Oklahoma City Zoo

OKLAHOMA CITY – Zookeepers say they are keeping a close eye on one of Oklahoma City’s most well-loved gorillas.

The Oklahoma City Zoo’s veterinary care team is monitoring Tatu, a 41-year-old silverback Western lowland gorilla.

Zoo officials say Tatu started showing signs of “unusual behavior” last Wednesday.

On Thursday, the veterinary team conducted a full medical exam.

However, the zoo did not release details about his condition, simply saying that Tatu has “lived well beyond the median life expectancy for male Western lowland gorillas, which is approximately 31 years old.”

Tatu joined the Oklahoma City Zoo in 1983 when he was just 8-years-old and has since become a guest favorite at the Great EscApe habitat.

Western lowland gorillas are native to the lowland forests of central and western Africa and are critically endangered.
