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.

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.
