The Dallas World Aquarium is an aquarium and zoo located in the historic West End district of downtown Dallas. The aquarium aims to house many endangered or endangered animals as part of a collaborative breeding program with other zoos around the world. The aquarium has two levels. The upper level of the aquarium is an artificial reproduction of the Orinoco rainforest, where birds such as the scarlet ibis and toucans soar freely. As they make their way through the rainforest, visitors see animals such as electric eels, birds, poisonous frogs, crocodiles and vampire bats. The lower level houses aquariums featuring fish, sea anemones, corals, jellyfish and other marine animals from around the world.
