Sea Slug Discovery on the Beach

The state park pamphlet suggested we investigate the seaweed. We shook some out in water and drained the water to find a sea slug of some kind! The other seaweed clumps didn't find anything exciting. Making the most of the seaweed covering the beach! Granted, they would rather be in the water or digging. You can't tell by the picture but it was user colorful. Lots of little dots of color amid the slime ball.
