There are more than 20,000 aquatic animals and plants at this entertaining attraction. The exhibits follow a drop of water from the springs of the Florida Wetlands Gallery, through a mangrove forest in the Bays and Beaches Gallery, and out onto the Coral Reefs, where an impressive 43-foot-wide, 14-foot-tall panoramic window lets you look out at schools of fish and lots of sharks and stingrays. Also worth visiting are the educational Explore a Shore playground, a deepwater exhibit, and a tank housing moray eels. You can look for birds and sea life on 90-minute Eco Tour cruises in the Bay Spirit, a 64-foot catamaran. The aquarium also offers a Dive with the Sharks program (tel. 813/367-4005) that gives certified divers the chance to swim with blacktip, sand tiger, and nurse sharks for 30 minutes. Don't be surprised if you come face to face with the 250-pound Goliath Grouper during the dive. The $150 price tag includes a souvenir photo and T-shirt. The Penguin Promenade allows you to get up close and personal with the cute creatures. Also popular and interactive is Ocean Commotion, a high-tech gallery utilizing state-of-the-art technology like "smart Wi-Fi," floor-to- ceiling interactive displays, virtual dolphins and whales, animation, and multimedia presentations. Guests can even upload their own videos to become part of the exhibit. Also fun for the adventurous: Swim With the Fishes, in which you can scuba through the 1/2-million-gallon Coral Reef Exhibit. Kids must be 6 or over and those under 9 must have an adult with them. Cost is $85 per person, which includes aquarium admission. Accompanying parents must pay, too. Expect to spend 3 to 4 hours here.
