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.

Barbronia weberi (Clitellata, Hirudinida, Salifidae) has ovary cords of the Erpobdella type
Journal of Morphology, 2013ABSTRACTThe organization of the ovaries in representative of the Salifidae (Hirudinida, Erpobdelliformes) was studied at the ultrastructural level for the first time. Like in other leeches, the ovaries of Barbronia weberi are composed of an outer envelope (i.e., an ovisac made up of two coelomic epithelia, muscle cells, and connective tissue) and ...

Reproductive strategies of Erpobdella punctata (Hirudinoidea) in two temporary ponds
Oikos, 1977The reproductive strategies of Erpobdella punctata (Leidy) were studied in two limnologically similar temporary ponds in Alberta. In Cairn Pond, E. punctata was the dominant erpobdellid, but in Jail Pond Nephelopsis obscura Verrill was dominant. In Jail Pond, E.

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.

Internationale Revue der gesamten Hydrobiologie und Hydrographie, 1983
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.

The Feeding Strategies of the Leech Erpobdella octoculata (L.): A Laboratory Study
International Review of Hydrobiology, 2003AbstractThe feeding behaviour of the freshwater leech Erpobdella octoculata was analysed by exposing potential invertebrate and vertebrate prey organisms (alive, wounded or dead) to leech attack in dishes, in the laboratory. The fact that E. octoculata is a macrophagous feeder that swallows living prey organisms whole (preferentially Chironomus larvae)

American Midland Naturalist, 1970
The life history, fecundity, behavior and feeding habits of the North American leech, Erpobdella punctata, are investigated. There is evidence of an upstream migration in early spring. The size distribution within populations indicates that growth to maturity took one year in a permanent pond, but two years in a stream, perhaps because the stream dried

Comparative Biochemistry and Physiology Part A: Physiology, 1974
Abstract 1. 1. The high content of proline and of bulky amino acid residues and the amorphous X-ray diffraction pattern suggest that much of the protein of the egg capsule of Erpobdella octoculata is amorphous. 2. 2. The sharp thermal transition, the presence of banded fibrils apparently composed of 15 A filaments and the amino acid ...

Sensilla of the predaceous fresh-water leech Erpobdella montezuma were examined by scanning and transmission electron microscopy. Densities of sensilla and cilia within each sensillum were highest in the anterior-most annulus and were less in more posterior annuli.
