PADI Underwater Naturalist Specialty

See the Ocean in a Completely New Way with Sea Dwellers Dive Center

Transform the way you experience every dive with the PADI Underwater Naturalist Specialty Course at Sea Dwellers Dive Center in Key Largo. Priced at $285, this specialty course teaches you how to better understand marine ecosystems so you can recognize behaviors, relationships, and species interactions that most divers overlook.

Instead of simply observing fish and coral, you’ll begin to understand how everything in the underwater world is connected—turning every dive into a richer, more meaningful experience.

Why Take the Underwater Naturalist Course?

Even familiar dive sites become exciting again when you understand what’s happening beneath the surface. This course is designed to help divers develop a “naturalist mindset,” allowing you to interpret marine life behavior and ecological relationships in real time.

You’ll learn to:

• Identify common marine life groupings and behaviors
• Understand predator-prey relationships in reef ecosystems
• Recognize symbiotic relationships between species
• Observe how marine environments function as interconnected systems

This course is perfect for divers who love marine life, enjoy slow exploration, or want to deepen their appreciation of ocean ecosystems.

What You’ll Learn

The Underwater Naturalist Specialty combines classroom knowledge with two open water dives, allowing you to apply what you learn in real reef environments.

Marine Ecosystems & Life Groupings

You’ll gain a clearer understanding of how marine organisms are classified and how different species interact within reef ecosystems. This helps you move beyond simple identification and into true ecological awareness.

Symbiosis & Species Relationships

Learn how marine life depends on relationships such as mutualism, commensalism, and predation. These interactions are constantly happening around you during every dive.

Predator-Prey Behavior

You’ll discover how predators and prey behave in natural reef environments and how these interactions shape underwater ecosystems.

Responsible Interaction with Marine Life

Understand how to observe marine life responsibly without disturbing natural behaviors or fragile habitats.

Reading the Reef Environment

Learn how to “read” a dive site—recognizing signs of feeding activity, cleaning stations, hiding behavior, and reef health indicators.
