About spanish dancer

Spanish dancers are the largest nudibranchs in the world, up to 60 cm of vivid red body with a yellow margin. When threatened or moving between coral, they swim by undulating the entire body's outer margin in flowing waves, exactly like a flamenco dancer's skirt.

They host commensal emperor shrimp (Periclimenes imperator) on the body, small white-and-red shrimp that ride along on the nudibranch and pick parasites in return for protection.

Reliable across the Indo-Pacific: Maldives, Andaman, Bali, Red Sea, Komodo. Night dives produce the active swimming displays; daytime they fold up tighter against coral.
