Elderly sloth bear dies at National Zoo

WASHINGTON — A 27-year-old male sloth bear named Merlin has died at the National Zoo after an illness that lasted two days.

Officials say Merlin underwent a routine examination Monday, but his recovery from his anesthetic drew concerns. He also had a history of stomach problems. Veterinarians performed additional tests and surgery to correct a twisted spleen.

The zoo says Merlin was placed on 24-hour watch for two days but died Wednesday morning.

Merlin was born at the zoo in December 1981 and fathered seven cubs. The zoo has two female sloth bears on exhibit.

Scientists estimate there are 6,000 to 11,000 sloth bears remaining in the wild. They are considered a vulnerable species.

According to zoo records, the oldest male sloth bear in captivity died at age 29.
