The world under the sea is vastly different from the world we live in. Beneath the waves, colorful fish swarm in massive schools, complex coral structures intertwine, and bashful mermaids don clever manatee masks. To give land-dwellers access to this realm, Underwater World helms scuba diving classes. Their sessions range from the Discover Scuba Experience for beginners to certification sessions to more advanced skills courses, such as the Enriched Air Nitrox class. They also educate divers with clinics that can enhance scuba excursions, covering subjects such as Caribbean and Pacific fish identification and underwater photography.
