Horned Nudibranch

Fascinating facts about the Horned Nudibranch

• At just 50 mm long, about 2 inches (5.08 cm), this sea slug packs a neon-orange head stripe and white-lined cerata that make it impossible to miss. Those bright bands run down its mantle, flashing like a painted fence on the ocean floor. Such vivid warning colors tell predators the nudibranch is toxic, a visual cue that lets it roam openly without a protective shell, turning its looks into a survival shield.
• Although it prefers tunicates, the nudibranch's menu reads like a seafood buffet: hydroids, anthozoans, crustaceans, other nudibranchs and even jellyfish polyps. While munching, it harvests undischarged nematocysts from its prey and stores them in its cerata, turning enemy stinging cells into its own armor. This clever chemical theft lets it deter predators without needing a hard shell.
