This is another small to medium sized species relatively common under rocks on seaward, pinnacle and lagoon reefs.
A color variant.
The small white ball with the pair of whitish tails roughly in the middle of the photo below is a copepod living commensally on the body of the flatworm. We often see these copepods in different colors living with nudibranchs, but this may be the first time we have personally seen one on a flatworm.
The pair of white tails extending below the copepod are its egg cases.
A tiny juvenile on white sponge or tunicate.
