Mitochondrial DNA Part A, 2014
Erpobdella octoculata (Linnaeus, 1758; Hirudinea: Arhynchobdellida: Erpobdellidae) is a very common and morphologically variable macrophagous predators of aquatic invertebrates. Here we determined the complete mitochondrial DNA (mtDNA) sequence of this species, as the first representative of the suborder Erpobdelliformes.

Relationship between neurosecretion and spermatogenesis in the leech, Erpobdella lineata
Comparative Biochemistry and Physiology Part A: Physiology, 1986Abstract 1. 1. The central nervous system in the leech, Erpobdella lineata, consists of 21 pairs of cell compartments. 2. 2.AF (aldehyde fuchsin) positive α-cells were observed in the buccal ganglion, cell compartment 8 or 9 and the subesophageal ganglion, cell compartment 11. 3. 3.

The Erpobdella testacea cocoon membrane is studied for the first time by transmission and scanning electron microscopy. It has an ovoid form, displays a cambered dorsal side in which various micro-organisms are attached and a flattened ventral side. Symmetrically positioned, 2 opercula occur at the distal ends of the cocoon. The internal ultrastructure

The diet of Erpobdella octoculata (Hirudinea: Erpobdellidae) in two Danish lowland streams
Fundamental and Applied Limnology, 1997The diet of leeches and the effect of prey size on feeding success were examined using gut analyses of Erpobdella octoculata from two Danish lowland streams. Five weight (size) classes of leeches were examined. For each insect prey found in the guts the width of the head capsule was measured.

Zoomorphology, 2001
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

AbstractThe natural feeding and competitive interactions between populations of Erpobdella ostoculata and Erpobdella testacea were investigated in Lake Esrom, Denmark, during 1979/80. Statistical analysis revealed that the size of the leeches was the main factor involved in resource utilization.
