Chemosensory detection of prey by Nephelopsis obscura (Hirudinoidea: Erpobdellidae)
Hydrobiologia, 1982The chemosensory detection of prey by the freshwater leech Nephelopsis obscura (Erpobdellidae) was investigated in the laboratory. Without direct tactile contact N. obscura of all three size classes tested were unable to detect and react to any of the prey types (Gammarus lacustris, Chironomus sp., Tubifex sp) or prey conditions (live, asphyxiated ...

Histopathology of hyperoxia in Nephelopsis obscura (Hirudinoidea: Erpobdellidae)
Journal of Invertebrate Pathology, 1987Abstract Small (10–15 mg) and large (300–350 mg) Nephelopsis obscura in the laboratory were exposed to supersaturated oxygen (250–300% saturation) at 4° and 15°C simulating winter and summer field conditions in southern Alberta. The results for both weight groups at both temperatures were very similar.

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.

Cosexuality in the Leech,Nephelopsis obscura(Erpobdellidae)
International Journal of Invertebrate Reproduction and Development, 1988Summary Hermaphroditism of the erpobdellid leach Nephelopsis obscura is described on the basis of macroscopic and histological studies of the gonads. Perivitellogenic cells (female primordial germ cells) proliferate from the septa of segments XII and XIII in individuals of 26–30 mg and spermatogenic cells from segments XII to XIII of 20–25 mg specimens.

A cave leech (Hirudinea, Erpobdellidae) from Croatia with unique morphological features
Zoologica scripta, 2001Croatobranch:es mestrovi is a troglobitic leech from deep shaft-like caves in the Uelebit Mountain, Dinaric karst, Croatia, living in cold (4-6 °C) water. Its oral sucker extends to form four pairs of triangular tentacles, each with about five finger-like papillae, but widening into a marginally crenulated disc whe~ attached to a substrate.

Mites (Acarina: Astigmata) associated with adult freshwater leeches (Hirudinea: Erpobdellidae)
Journal of Natural History, 1997Two species of mites (Astigmata: Acarina) were found crawling on the integument of cultured Nephelopsis obscura, a common North American leech. This is the first record of an association between mites and adult annelids. Histiostoma anguillarum (Histiostomatidae), previously described as an associate of farmed freshwater eels, were recorded in ...
