Interinstitutional transport and anesthetic management of two captive-born lowland tapirs (Tapirus terrestris) across an altitudinal gradient in Ecuador
This paper reports the successful interinstitutional transport of two captive lowland tapirs across an altitudinal gradient in Ecuador, demonstrating that coordinated anesthetic planning, environmental management, and continuous veterinary monitoring can facilitate safe relocation with only minor, self-resolving complications.

Imagine the animal kingdom as a giant, bustling city where every species has its own neighborhood. Sometimes, for the safety of the species or the health of the individuals, animals need to move to a new neighborhood. This is the world of zoological conservation, where veterinarians and caretakers act like expert movers, trying to relocate large, sensitive creatures without causing them stress or injury. One of the trickiest jobs involves moving "perissodactyls"—a fancy word for odd-toed hoofed mammals like horses, rhinos, and tapirs. These animals are massive, easily stressed, and their bodies react strongly to being drugged to sleep for a trip. Moving them is like trying to transport a sleeping giant through a storm; you have to manage their temperature, keep them calm, and make sure the truck doesn't bump them too hard. Scientists are always looking for better ways to do this, because if we can move these animals safely, we can save them from shrinking habitats and keep their populations healthy in zoos and sanctuaries.
Now, picture two tapirs, the largest land mammals in South America, named Samir and Chiquita. They live in Ecuador, a country famous for its dramatic changes in scenery, from hot, humid jungles to cold, high mountain peaks. In May 2026, these two captive-born tapirs needed a new home. Samir, a male weighing 150 kg, and Chiquita, a female weighing 180 kg, were moved from Eco Zoo San Martín to Lago Real Zoo. The journey was a six-hour rollercoaster that crossed different climates and altitudes, starting at a cool 15°C, dipping to a chilly 9°C in the high Andes, and ending in a warm 22°C.
Getting them ready for the trip was the first big challenge. You can't just ask a tapir to hop in a crate; they need to be put to sleep first. The team used different "sleeping potions" for each animal. Samir got a mix of three drugs delivered by a dart from a distance, while Chiquita got a two-drug mix injected by hand. Chiquita was a bit of a tough cookie; the first dose didn't knock her out deep enough, so the team had to give her a little extra boost 15 minutes later. Samir, however, fell asleep quickly. Once they were out, the team checked their vital signs. Chiquita got a little chilly, her temperature dropping to 34.5°C, likely because the drugs made her body forget to stay warm and the air was cold. But she warmed up again before they left. Samir stayed steady.
The journey itself was a test of logistics. The tapirs were loaded into special crates that were covered up so they couldn't see the world rushing by, which helps keep them calm. The team drove a diesel truck, with two veterinarians riding in a separate car to keep an eye on the animals through the windows and check on them during stops. It was a long drive, but the animals handled it well. When they arrived, there was one small hiccup: Samir had a tiny scratch on his back. It turned out he had bumped into some exposed metal bars inside his crate while the truck was moving. It wasn't a big deal, though; a little honey and aloe vera fixed it up in a few days.
Once they were let out of the crates at their new zoo, the tapirs didn't act scared or confused. They immediately started exploring, sniffing around, and even found some oranges on the ground to eat. Within an hour, they were eating their regular food, and soon after, they were swimming in their new pool. The team watched them closely for a month, and everything looked perfect. No one got sick, no one was stressed, and they both seemed to love their new, spacious home.
This story shows that moving big, tricky animals like tapirs across long distances and changing weather is possible if you plan carefully. The team learned that covering the crates helps keep the animals calm, that you need to watch their body temperature closely when it's cold, and that your transport crate needs to be padded so no one bumps into metal bars. While this specific success was with tapirs that were used to humans, the methods used here suggest that with the right mix of drugs, good drivers, and careful monitoring, we can safely move these magnificent creatures to new homes when they need them.
