One of North Sulawesi's most photographed nudibranchs, Chromodoris magnifica displays vivid white, red, and black banding that advertises its toxicity to predators — the coloration mimics the chemistry of the sponges it eats. Nudibranch diversity at Siladen is exceptional; the island's rubble and low-profile coral gardens support dozens of species simultaneously, making it one of the most reliable nudibranch diving locations in the Coral Triangle.
