This striking nudibranch moves like a jeweled ember across the reef, its dark body washed in deep forest green and midnight blue. Thin lines of glowing orange trace its contours, while its raised ridges and knobby textures give it a sculpted, almost armored appearance. Bright orange rhinophores and gills crown its back like small flames, marking every slow, deliberate step with vivid contrast.
