Transform your underwater observations by learning to identify and group the hundreds of tropical fish species inhabiting Koh Lanta's reefs.

1. Why Take This Specialty Course?

Take a fresh look at the underwater world by naming what you see. Have you ever returned from a dive or snorkeling trip wondering, “What was that colorful fish?” The SSI Fish Identification specialty gives you the tools and knowledge to recognize fish families, identify specific species, and understand their behaviors. Instead of seeing a wall of random fish, you will start recognizing habitats, feeding habits, and unique relationships, making every aquatic outing far more engaging and rewarding.

  • Family Classification: Learn to group fish by body shape, fins, and markings rather than trying to memorize hundreds of individual species.
  • Habitat & Behavior Observation: Discover where different species hide, how they feed, and how to spot camouflaged fish.
  • Fish Survey Techniques: Practice counting and recording marine life, skills used by marine biologists and citizen scientists worldwide.
  • Open to Everyone: Academic course accessible to scuba divers, freedivers, and snorkelers.

2. Course Curriculum (1 day in ocean or theory only)

The course combines interactive online learning on the MySSI app and a topic presentation at the center with your instructor (with an optional practical application during your ocean dives).

🔹 Key Topics Covered:

  1. Fish Families & Anatomy: Key physical features, fin structures, and body shapes used to classify reef fish.
  2. Reef Fish of the Andaman Sea: Focus on emblematic families of Koh Lanta, including Butterflyfish, Angelfish, Parrotfish, Damselfish, Snappers, and Groupers.
  3. Observational & Recording Skills: How to use underwater slate slates and fish ID guides to log your sightings accurately.

3. Prerequisites

No diving prerequisites required (also accessible to non-divers, freedivers, and snorkelers).

  • Minimum Age:  10 years old for divers and 6 years old for non-divers.

4. Your International Certification

  • Counts toward your Master Scuba Diver rating and can count as one of the 5 adventure dives for your SSI Advanced Open Water Diver certification (when combined with ocean dives).

5. Frequently Asked Questions (FAQ)

Do I need to scuba dive or snorkel for this specialty?

No, it is not mandatory! The Fish Identification specialty can be completed entirely as a 100% dry course.

If you are a non-diver or prefer to stay out of the water, you can earn your certification by completing the interactive classroom or online sessions.

However, if you are a diver or snorkeler, adding in-water sessions is highly recommended: it’s the perfect opportunity to apply your new knowledge to real fish and practice identifying families!

Do I need to memorize all the fish species in the ocean?

Not at all! The course teaches you a system based on fish families and physical characteristics. Once you know the family, finding the exact species in an identification guide becomes quick and easy.

Is this specialty useful for photography or video?

Yes! Knowing fish behavior and habitats allows you to anticipate their movements, approach them without scaring them, and capture much better photos and videos.
