The name of this one refers to the gill color, which varies from orange to purple. When it has orange gills, it externally looks a lot like the purple form of Hypselodoris iba, and it is possible some of the photos below are that species. We have seen it at Bubbles, Red Rock, Bethlehem and Basura.
The next two have marginal color like Hypselodoris apolegma, but the purple gills suggest H. variobranchia.
