This tiny, but beautiful, flatworm (15 -20 mm) was found in a most unlikely place: in terrible, surgey conditions, in less than 1 metre of water on what appeared to be a battered, dead piece of coral swirling around in brown/foamy soup.  The striking fuchsia colour drew enough attention that I turned my swim around, broken coral in hand, and headed out to clearer water where I could actually see what I was looking at.  Unfortunately, it appears that the worm was slightly beaten up as well. After documenting as best I could,  I dove to 3 metres and wedged its host piece of dead coral into one of the secretion sponge-covered platforms that have formed along Ma’alaea Bay.  I’m hoping the flatworm survived.
