Luminoflora Aurantius, named from Latin 'lumen' (light) and 'aurantius' (orange-yellow luminescence), is a bioluminescent aquatic plant in the Illuminaetherea Petalens cluster. It grows 10-30 cm tall, weighing 50-200 g, inhabiting deep ocean reefs at 0-10°C. Flowers exhibit radial symmetry with translucent, undulating, blue petals edged with ruffled margins and orange speckling. Petal cores emit orange bioluminescence at 470-530 nm via luciferin-luciferase chemistry. Semi-rigid stems undulate with currents. Classified in a rare protected family of 10 species, it provides nocturnal illumination to attract bioluminescent plankton and crustacean pollinators, enabling unique low-light pollination. Its rarity and temperature sensitivity make it a key reef health indicator.
