The digestive cells of many polyopisthocotylean gill-parasitic monogeneans are characterized by granular inclusions in the form of a brown-black pigment (Llewellyn 1954; Halton and Jennings 1965). In Diclidophora merlangi, the pigment is confined to within a lysosomal system of membrane-limited channels, and its presence is believed to be the result of the intracellular digestion of host haemoglobin (Halton et al. 1968; Halton 1975). Empirical solubility and bleaching tests have suggested the…

TLDR
The present investigation is concerned with the ultrastructure of the cecal epithelium of D. merlangi and represents part of an electron microscope study of the absorptive surfaces of this worm.
Observations on the food and the gut pigment of the Polyopisthocotylea (Trematoda: Monogenea)
TLDR
It has been shown by spectroscopic and histochemical methods that eight representative species of Polyopisthocotylea feed mainly on the blood of their hosts, and in a more limited sample of skin-and cloaca-inhabiting Monopists there was no evidence of a blood-feeding habit.
Observations on the nutrition of monogenetic trematodes.
1. A comparative study has been made of the food, feeding mechanism, gut structure and digestive processes in representatives of the two sub-orders of the Trematoda Monogenea.2. The two sub-orders
Intracellular digestion and cellular defecation in a monogenean, Diclidophora merlangi
TLDR
It is suggested that a lysosomal system operates in the digestive cycle of the haematin cell of Diclidophora merlangi, which can result in the complete evacuation of pigment from the cell in worms starved of food.
