Spanish Shawl

Flabellinopsis iodinea

Spanish shawls navigate rocky reefs and kelp forests along the eastern Pacific coast, using luminous purple bodies and brilliant orange cerata to advertise their stolen stinging defenses. When threatened by floor-dwelling predators like predatory sea slugs, they flex their bodies vigorously from side to side in an undulating swimming motion to escape into open water. They feed almost exclusively on hydroids, sequestering the stinging cells unharmed in their cerata to deter fish and crabs.

Responsible observation
  • Tidepool Etiquette: Look for them on hydroid colonies in deep, calm low-tide pools without disturbing rocks.
  • Diver Buoyancy: Maintain neutral buoyancy over reefs to avoid kicking up silt or crushing delicate nudibranchs.
