Nembrotha lineolata appears relatively common, observed at a number of sites around Pohnpei, including Mwand, Palikir, Pelim, Tawak, and Arou Passes.
The one below appears to be going for the tunicate right in front of its mouth on the left side of the photo.
This one is definitely eating a large tunicate.
