Underwater Naturalist

Underwater Naturalist Adventure and Specialty Dives

Diving is all about what you see beneath the surface. When you’re underwater, you’re in a world filled with fascinating creatures, plants and other-worldly landscapes.
Admiring the beauty beneath the waves is one thing, but appreciating how the underwater environment functions, on a more complex level, is something that will enhance your diving experiences in ways you might not expect.

The better you understand the aquatic environment, the more you’ll be able to savor the sights you encounter on your dives. In this course, you’ll learn how the interaction of fish and plant life effect the environment and each other.

This and so much more can be learned when you’re participating in our Aquarium Underwater Naturalist Adventure Dive and Specialty.
