Coral Identification

Discover the living foundations of the ocean and learn to identify the hard and soft coral species that create Koh Lanta's vibrant reefs.

1. Why Take This Speciality Course?

Take a fresh look at the living architects of the reef Coral reefs are among the most biodiverse ecosystems on the planet, yet many people mistake corals for colorful underwater rocks or plants. The SSI Coral Identification specialty opens your eyes to the fascinating world of coral polyps and their complex colonies. By learning to distinguish hard corals from soft corals and recognizing different growth forms, you will gain a deep appreciation for reef health and see every underwater landscape in a whole new dimension.

- Hard vs. Soft Corals: Learn the key biological differences between reef-building stony corals (Scleractinia) and flexible soft corals (Octocorallia).
- Growth Form Classification: Master identification by observing structures like branching, boulder, plate, encrusting, and brain coral forms.
- Coral Health & Bleaching: Discover how corals feed, reproduce, and how to spot signs of stress, bleaching, or disease on tropical reefs.
- Open to Everyone: Academic course accessible to scuba divers, freedivers, and snorkelers.

5. Frequently Asked Questions (FAQ)

s it difficult to distinguish different coral types?

Not at all! Rather than memorizing scientific names right away, the course teaches you to categorize corals by their growth shapes and polyp structures, making identification simple and fun.

Why is coral identification important for divers and snorkelers?

Understanding corals helps you recognize healthy reef habitats, avoid accidental contact with fragile or stinging species, and appreciate the foundation that supports all marine life.
