Hawksbill Turtles

Named for their distinctive, pointed beaks, are a frequent sight in the Similan Islands. Unlike green turtles, hawksbills are omnivorous and often feed on sponges, anemones, and small invertebrates.

Conservation efforts in the Similan Islands aim to protect these turtles and their delicate coral reef habitat.


Anemonefish (Clownfish)

These small, brightly coloured fish, with their distinctive orange bodies and white stripes, live among the tentacles of sea anemones.

This unique partnership benefits both species— the anemone provides shelter and protection, while the clownfish helps keep it clean and free from parasites.
