The Disco Clam, aptly named for very obvious reasons, supposedly uses it’s own light display to attract food.

Although it appears that the clam produces it’s own light, it instead rapidly rolls and unrolls the reflective membrane on the outer lips of the shell creating the illusion of light.

Once possible prey comes close enough the clam then discharges an acidic mucous which makes the prey immobile.
