The beautiful pink Tritoniopsis elegans, a marine gastropod mollusk that is often confused with sea slugs, first was scientifically discovered in the Red Sea. The range of this nudibranch spans the western Indo-Pacific. Of all the wildly beautiful traits that these creatures possess, their color is perhaps the most remarkable. Ranging in a spectrum from soft and dessert-colored to neon rainbow, they have evolved these hues for means of both camouflage—when matching their environment—and as a warning.
