A Marine Snail that has Luminescent Shell

From I fucking love science

The shell of Hinea brasiliana amplifies the light and the faint glow this produces illuminates the whole shell surface. When the snail retracts into its yellow shell to avoid a predator, the shell still glows. The shell’s glow is colour-specific: the glow is only produced when the snail produces its blue-green light. Researchers believe the shell’s glow also reflects onto persistent predators like crabs, who are then ‘highlighted’ so they are easy to spot by their own predators.
