Saving a patient can be an adrenaline pumping experience for any doctor - but for Zookeepers in Denver, the fact they were trying to resuscitate a baby Tapir added an extra element of challenge.

On September 3, the zoo's senior female Tapir Rinny gave bith to a tiny baby, but keepers watching on CCTV realised she could not break the amniotic sac.

With the baby's lungs filling with fluid, vets had to step in and perform several minutes of mouth-to-mouth resuscitation on the newborn.

Eventually, the endangered youngster started breathing on its own. He seems to have made a full recovery, and has since been named Dumadi.
