Underwater Naturalist


Take the Underwater Naturalist Specialty course and you’ll see new things, even on the most familiar scuba diving sites. Why? Because when you know more about symbioses, underwater ecology, and aquatic plant and animal habitats, you notice behaviors and see creatures you may have previously missed. Learn more about the local ecosystem and take a closer look on your next scuba diving adventure.

(Junior) Open Water Divers who are at least 10 years old are eligible to take the Underwater Naturalist Specialty course.


Through class discussions and on two scuba dives, you’ll learn:

  • Key differences between the terrestrial and aquatic worlds.

  • Major aquatic life groupings, interactions and information that dispels myths.

  • Responsible interactions with aquatic life.

The first dive of this Specialty Diver course may credit as an Adventure Dive toward your Advanced Open Water Diver certification – ask your instructor about earning credit.


Besides your basic scuba equipment, you’ll need a slate and pencil to record your observations. Ask your Instructor about additional equipment you may want, such as a dive light to better see into cracks and crevices.

Getting Started

Sign up for the course then receive your Underwater Naturalist Manual. After reading the manual and filling out the Knowledge Review, you’re ready to meet with your Instructor and plan your underwater naturalist dives.
