D.B.
Corpus Christi has a wonderful Aquarium that has special featured shows with otters, seals, dolphins. You can even go under the tank of the dophins and watch them from the under water vantage. A lot of the "critters" are rescue and rehabilitated success stories. There is also a ship very close to the Aquarium (The Lexington) which you can go on board and tour at your own pace. It has a flight deck with planes and helicoptors to see. There is a flight simulator and a I-Max 3-D show. Enjoy Your Trip!
