Mauve stinger jellyfish glows in the ocean's twilight zone

Original: The mauve stinger (Pelagia noctiluca) doesn't need the sun to shine. Down in the ocean's twilight zone, it makes its own

The mauve stinger jellyfish (Pelagia noctiluca) produces its own light through bioluminescence, glowing in the ocean's twilight zone where sunlight barely reaches. The faint glow startles would-be predators and attracts the plankton the jellyfish feeds on, letting it hunt and defend itself without any need for sunlight.

Why now: Striking facts about deep-sea bioluminescence regularly circulate among science and ocean enthusiasts online.
