Even when deprived of food for ten months, some individuals still had traces of blood in their gut, visible through their translucent outer surface. Growth was very slow and females did not mature until they were at least ten years old.

It has strong muscles in its oesophagus and large salivary glands and rapidly fills its dilatable hind gut with blood. It then drops off the fish and spends several months on the seabed digesting the blood. In a research study, specimens of

This isopod is very inactive, and most of its time is spent stationary, concealed in a crevice or under a stone on the seabed. It needs to feed very infrequently and when it does so it clings onto a host fish with its front three pairs of pleiopods. Younger specimens choose thin skin close to the
