Polyclad flatworms closely resemble nudibranchs in external appearance. The main distinguishing characteristic is the absence of external gills that are found on nudibranchs. This species is known for its free swimming behavior that makes it appear as if it is dancing in the water. It will actively swim in the water column to move from part of the reef to another. The worm dance may be a popular break dance move but flatworms give it a whole new meaning!
