Tropical World has a butterfly house and aquariums. There are many birds and some reptiles living free inside, and many other animals in enclosures including a popular group of meerkats. A nocturnal house has creatures such as bats which are active at night. In 2015 following further refurbishments a new Aztec zone opened that included the aquarium area being transformed into a new Amazon themed zone where you can see new residents including piranhas and salamanders.
