The Dallas World Aquarium is pretty cool! It's built in an old warehouse. You start at the top where they have birds and monkeys, and kinda walk down in a spiral towards the bottom. it's like walking down the various levels of an ecosystem surrounding a tropical lake. Eventually you get to ground level where the biggest pools are. They have some BIG alligators, and in another, deeper, tank, they have 3 manatees. You can go to a lower level and watch them swim below the surface with turtles, rays, and other large fish.
They also have a pair of river otters that are just plain fun to watch!
