UNDERWATER NATURALIST The ecology of the underwater world

The PADI Underwater Naturalist Course

Look closer to see more on your next dive. Look for symbioses, predator-prey and other relationships between aquatic plant and animal life. Learn not just what fish and animals are, but how they interact with each other and the environment.

The Fun Part

Learn about why some creatures behave the way they do and what their role is in the aquatic ecosystem.

What You Learn

  • The major aquatic life groupings, interactions and factual information that dispels negative myths
  • The role of aquatic plants, food chains and predator-prey relationships
  • Responsible interactions with aquatic life
  • The underwater naturalist’s view of organisms and their roles in the environment

You put this information into practice during two open water dives.


  • PADI (junior) Open Water Diver (or hold a qualifying certification from another training organization) or enrolled in the PADI Open Water Diver course
  • 10 years or older
