Mayo, a mountain tapir, was orphaned in Nariño, Colombia after his mother was killed by hunters in 2014. Just eight days old, he was in critical condition when he was rescued, but the staff at Zoológico de Cali worked quickly to save the infant.

For five months, Mayo was cared for by veterinarians and medical technicians, according to El País, and he was finally ready for the next stage of his life: sharing a habitat with another tapir at the zoo.

Every day, for an hour at a time, "Mayito" and Cedona, a 15-year-old tapir living at the zoo, would get the chance to observe each other, snuffle and sniff and get used to each other. After a month, Mayo and Cedona were ready to be roommates.

Cendona, being "longer in the tooth" than Mayo, was not used to an energetic toddler running around. Mayo is a mischievous tapir who likes to play in the water and play hide-and-seek, according to El País. Cedona eventually grew accustomed to the antics of the little tapir and became a "great teacher."

Mountain tapirs are listed as "endangered" on the IUCN Red List of Threatened Species and are currently protected by law. Mountain tapirs, tapirus pinchaque, can be found in Columbia, Ecuador and Peru, according to IUCN. Threats facing mountain tapirs include loss of habitat, poaching (for food and for body parts used in folk medicine) and the introduction of livestock, which has brought diseases unfamiliar to the tapir's immune system and has also attracted predators.

There are other types of tapirs - such as Baird's, lowland and Malayan - but mountain tapirs are the smallest of the tapirs at three feet high, six feet long and more than 550 pounds (0.8 meters tall, 1.8 meters long weighing 250 kilograms). Tapirs are timid and shy, which makes them solitary creatures. Tapirs are crepuscular (coming out when it is cooler) and live off of vegetation, which they typically look for at night. They have great vision and a great sense of smell - just look at that prehensile mini-trunk! Tapirs are "odd-toed ungulates" (they have three toes on their back feet and four toes on their front feet) and are most closely related to rhinos and horses. They plod along and saunter slowly, but can run quickly in bursts and are great swimmers.Tapirs can live to the ripe age of 20, according to the San Diego Zoo.
