Phyllodesmium parangatum is characterized by relatively cylindrical milky white cerata, which have curved white apices. The translucent white rhinophores are relatively short and thick, the elongate oral tentacles are also translucent white and longer than the rhinophores. It is a smaller species growing up to 20 mm. The body colour ranges from a translucent white to a milky yellow with a brownish tinge.
The name of this species 'parangatum' is derived from the Filipino words parang gatas referring to the milky colour of the living animals.
Pretty similar is:
Phyllodesmium magnum which is a larger species, up to 130 mm length, and has more flattened brownish cerata, often with a bluish tinge and yellowish apices. It differs also by the position of the anal papilla. Let me quote IPN: "There are also major internal differences in the form of the radula and jaws."
