Actinobdella inequiannulata was found on the white sucker, Catostomus commersoni, and less frequently on the longnose sucker, Catostomus catostomus, in Algonquin Provincial Park, Ontario, Canada. Catostomus commersoni parasitized with Act. inequiannulata was collected from July to October 1973 and May to October 1974.

The distribution, abundance and intensity of the annelid worm, Piscicola geometra(leeches) infecting Oreochromis niloticus cultured in a rainforest fish pond, South Eastern Nigeria was studied over a 12 months period. Three hundred fish were examined of which 48.3% were infected. Infection occurred throughout the year, with a peak in February.

General and comparative endocrinology, 1983
The body water content of Theromyzon tessulatum changes considerably during the life cycle. Water content is low and undergoes little change during the first stages, but it strongly and regularly increases during the last stage prior to reproduction. It is controlled by a water balance factor (FRBH) released by the brain.
