VIDEO: Dolphins dazzle while feeding in Mediterranean Sea

GIBRALTAR (WILX) -- Here's some cool video showing a pod of dolphins delivering some unusual entertainment.

Look what the onlookers got to see in the Mediterranean Sea. They're feeding on bio-luminescent plankton.

The boat was off the coast of Gibraltar for the rare sight.

The tiny organisms emit the light as a form of defense, illuminating their prey who themselves become more vulnerable to other predators.
