(AP) PITTSBURGH - A gorilla born in February at the Pittsburgh Zoo & PPG Aquarium has died, though zoo officials say it will take several weeks to determine why.
Zoo officials had not named the male gorilla. It had been born Feb. 9 to Moka, a 15-year-old gorilla brought to the Pittsburgh zoo from one in Miami in 2007.
Barbara Baker, the zoo's president and chief executive officer, says the gorilla appeared lethargic and weak in its mother's arms on Friday. She says the animal was transferred to the zoo's new Animal Care Center where he died Saturday.
Zoo officials announced the death Monday.
The gorilla had been the first born at the zoo since 2001.
The gorilla's 20-year-old father, Mrithi, was the first gorilla born at the zoo.
