Become an Underwater Naturalist Instructor Koh Tao

The most popular reason for people learning to scuba dive is to experience the incredible diversity of aquatic life and Coral reefs.

This amazing ecosystem boasts incredible biodiversity and it is often called the rainforest of the ocean, supporting 25% of marine life in the world, yet only covering 0.1% of the planet.

As a PADI Dive Instructor, we need to understand how Coral reefs function, so that we can introduce our student divers to this amazing underwater environment.

We also need to understand how different marine life interacts with Coral reefs and as a scuba diver how we should interact with this spectacular world.

Learn to Teach PADI Underwater Naturalist Specialty Course

The PADI Underwater Naturalist Instructor specialty course will teach you exactly how to do this in an exciting and enlightening way.

Our Instructor Specialty course will give you the additional knowledge and skills necessary to teach your students a little bit more and encourage them to become a passionate Underwater Naturalist

The PADI Underwater Naturalist specialty course is designed to teach student divers how to interact with marine life and the Coral reef.
