In early developmental stages of Erpobdella octoculata two pairs of transitory nephridia occur which degenerate during the formation of the body segments. Because in the ground pattern of Annelida the first nephridia formed during ontogenesis are protonephridia, it can be assumed that the transitory nephridia of E.

Freshwater Invertebrate Biology, 1985
During the study of the anatomy of mature Nephelopsis obscura and Erpobdella punctata the structure and distribution of the male and female reproductive organs were observed. The gonopores in N. obscura and E. punctata were separated by one and two annuli, respectively. In N. obscura, the multifollicular testes lie in two lateral columns in the form of

Erpobdella (Dina) parva complex (E. parva, E. dubia, and E. lahontana) were analyzed by species distribution, pigmentation, size, number and position of the labial eyes, tubercle presence, annulus width, gonopore position, and male genital atrium shape. I concluded that E. parva and E. dubia are conspecific, with the priority name of E. parva.

Comparative Biochemistry and Physiology Part A: Physiology, 1980
Abstract 1. 1. The ability of two species of freshwater leech to regulate their weight was examined in media between 6 and 900 mOsm/l. 2. 2. Nephelopsis obscura was able to maintain its weight from 100–207 mOsm/l while Erpobdella punctata could regulate between 58 and 200 mOsm/l and at 900 mOsm/l reached equilibrium at 1.8 times its ...

Octopamine in leeches—I. Distribution of octopamine in Macrobdella decora and Erpobdella octoculata
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1980Abstract 1. The nervous and other tissues of the leeches M. decora and E. octoculata were asayed for octopamine using a radiochemical-enzymatic technique. 2. Octopamine was found at mean concentrations of 12–40 ng/mg tissue protein in the ganglionated nervous tissue; lesser amounts of 7.4–19 ng/mg tissue protein were observed in the non-ganglionated

In laboratory experiments, eleven out of twenty-one invertebrate species and all of the three fish species tested fed on freshly laid flaccid cocoons of Erpobdella octoculata, though predation was only severe from a dytiscid beetle, E. octoculata and the fish species. There was a tendency for more cocoons to be eaten by starved than fed predators. Only

Seasonal Variation in the Respiratory Acclimatization of the Leech Erpobdella Testacea (Sav.)
Journal of Experimental Biology, 1958ABSTRACT In a preliminary study of the oxygen consumption of leeches (Mann, 1956), it was shown that Erpobdella testacea has an oxygen consumption which is independent of the oxygen concentration in the water, over the range 2–6 ml./l., provided that it has been acclimatized overnight to the oxygen concentration of the experiment.
