The ozobranchid leech, Ozobranchus margoi (Apáthy, 1890), parasite of the loggerhead turtle, Caretta caretta (Linnæus), was described through a multilevel approach including three different techniques: scanning electronic microscopy, histology and micro-CT.

Desserobdella phalera (Graf, 1899) n.comb. is redescribed. This glossiphoniid leech deposits cocoons directly onto the substratum and belongs, therefore, in the subfamily Glossiphoniinae. It has the following generic characters: diffuse salivary glands, two pairs of coalesced eyes, one pair of mycetomes, and subdivision of primary annuli in complete ...

In this study, two new species of Helobdella leeches, Helobdella octatestisaca n. sp. and Helobdella melananus n. sp., and a newly recorded species, Helobdella europaea, are reported. Morphological characters and DNA barcode analysis were used to identify the three new species.

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 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.

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.
