It’s been a bad week for Zoo Miami. Two of its larger animals died on Monday

First, a 12-year-old Malayan tiger named Tevy was found dead in her enclosure.

By nightfall, Mohan, at 44 believed to be the oldest living Indian rhinoceros in captivity, was euthanized due to failing health, said spokesman Ron Magill.

“His breathing had become very labored, and he was unsteady on his feet. It was a quality of life issue,” he said of the decision to end the rhino’s life on the same day Tevy died.

Mohan had been at the zoo since 1970. “He had arrived from Nepal as a youngster at the original zoo at Crandon Park,’’ Magill said. “He was a very emotional loss for us.’’

Mohan had been a gift from benefactor Ralph Scott, who donated other large animals to the zoo.

“He had not been on display for several years and had been retired and living in a quarantine area. He was just enjoying the final years of his life,” Magill said.

There are three other Indian rhinos at the zoo.
