Dana the lion-tailed macaque was put to sleep after her companion Lhasa died

Zoo employees have euthanised the companion of an aged lion-tailed macaque after the 29-year-old died of suspected pure causes in her sleep.

Lhasa was discovered lifeless in a sleeping place final weekend by keepers at Rockhampton Zoo in Queensland, leaving Australia’s final lion-tailed macaque, Dana, deeply distressed.

The 21-year-old was exhibiting indicators of extreme stress following the loss of life, together with fixed pacing, frantic alarm calling, and giving ongoing indicators of excessive stress.

Given the species are extremely social, zoo employees feared Dana’s psychological misery would solely worsen as time went on.

Information shared to the zoo’s web site revealed rehoming or pairing Dana with a unique species weren’t viable choices.

“It is very unlikely Dana would be accepted by a different species of primate and to attempt this would be dangerous for her at her age, as well as highly distressing,” a put up to the zoo’s Facebook web page learn.

“Lhasa was her world and after the years of companionship, Dana’s welfare was our top priority.”

The zoo burdened it could be merciless to ship Dana to a different zoo, the place she confronted being attacked and even killed within the means of being launched into one other troupe.

Lion-tailed macaques are regarded a “phase out” species by the Zoo and Aquarium Association (ZAA) which implies a brand new troupe can be notably difficult to import.

“And when that troop starts to age and pass, we would have the same problem again of only one or two left presenting welfare concerns again,” the web site states.

On prime of a time delay of six to 12 months, bringing in a troupe of monkeys for Dana would have introduced a bunch of latest difficulties.

Dana would endure psychological misery all through the ready interval, and there was no assure the monkeys would settle for her, given they work together and talk otherwise.

“While this decision has been heartbreaking for our zoo team and we will miss them both, we know that euthanasing Dana allowed her to die peacefully with Lhasa and not go through any unnecessary suffering,” the zoo’s Facebook put up learn.

“We have an incredibly supportive community here, that loves our zoo and we know will also miss Lhasa and Dana greatly.”

The species lives for about 20 years within the wild and between 25 and 30 years in captivity.
