In Baba's (1949) painting the digestive gland duct is dark brown, almost black, and there are fine white longitudinal lines down the cerata. It would seem that this is one of those species in which the colour of the ceratal digestive gland is determined either by what the animal has just eaten, or whether it has recently eaten.
