Plakobranchus papua Meyers-Muñoz & van der Velde, 2016
Plakobranchus is a genus of sea slugs, sacoglossans, marine opisthobranch gastropod mollusks in the family Plakobranchidae.
Plakobranchus papua is a common inhabitant of shallow coral reef pools and lagoons. It is seldom seen as it is well-camouflaged, half buried in the coral sand. Although to my knowledge it has never been studied by algal physiologists, it deserves their attention.
