Dear Ed,
Janthina and Recluzia belong both to the Janthinidae.
While Janthina is closely associated and feeds on Velella, Physalia and
Porpita,
all blue-violet hosts, Recluzia is associated among others with pelagic sea
anemones
of the genus Minyas, which are of a (pale-)brownish colour like the shells
of Recluzia.
