Florida zoos and aquariums follow highly sophisticated "ride-out" plans rather than evacuating animals, as transport is often more stressful and dangerous than the storm itself. Smaller animals, birds, and primates are moved into temporary kennels inside sturdy, climate-controlled administrative buildings. Larger animals, such as lions, rhinos, and giraffes, are secured in their "night houses," which are constructed of reinforced poured concrete and welded steel designed to withstand Category 5 winds and flying debris. Some animals have natural defenses; for instance, alligators and crocodiles simply submerge in their deep pools. Staff "ride-out teams"—including vets and keepers—stay on-site in bunkers during the storm to monitor the animals via cameras and provide immediate care once it is safe to emerge.
