Opened in 1992, The Dallas World Aquarium provides a little look into marine, freshwater and even terrestrial ecosystems. The aquarium itself houses a coral reef, kelp forest and even a 20,000 gallon walk through tunnel and features an array of marine life from around the world, including sharks and other marine life from the Yucatan Peninsula. The various terrestrial exhibits feature the biodiversity of wildlife from Borneo and the South American Rainforest. The aquarium also offers an educational component with hands on exhibits, touch screens and special programs for children. They’ve even been known on occasion to have a diver hold up a “Will You Marry Me” sign; you know, for the romantics.
