  • Ringuelet went on to publish 17 works of Arachnology, with one relating to the Order Scorpiones and the others to the Order Opiliones, 44 papers on the Hirudinea leeches, 24 on various crustaceans, and 14 specifically on Biogeography. (wikipedia.org)
  • They are divided into two groups: Arhynchobdellida and Rhynchobdellida Rhynchobdellida are "jawless" leeches, armed with a muscular, straw-like proboscis puncturing organ in a retractable sheath. (wikipedia.org)
  • Haematophagous parasites and disease vectors such as leeches, ticks, mites, lice, bed bugs, mosquitoes, and myiasis-causing fly larvae are common health problems in Lao Peoples Democratic Republic (Lao PDR). (diva-portal.org)
  • Dr. Ringuelet's research interests were exceptionally broad, including numerous studies of leeches (Hirudinea), harvestmen spiders (Opiliones), crustaceans, chironomid flies and Neotropical fishes. (wikipedia.org)
  • Its North American counterpart is Macrobdela decora, a much less efficient medical leech. (wikipedia.org)
  • This behaviour represents the most ancient state in leech evolution. (springer.com)
  • These unique parental care patterns within one family of extant freshwater leeches can be arranged schematically in a series of increasing complexity which may reflect the evolution of brooding behaviour. (springer.com)
  • We conclude that the major selective pressure driving the evolution of parental care in leeches may have been predation on eggs and juvenile stages. (springer.com)

  • With the exception of leeches, most annelids have tiny, hair-like bristles protruding from each body segment, which aid in motion and traction. (reference.com)
  • For example, leeches do not have bristles and the external segmentation of their bodies does not correspond with the internal segmentation of their organs. (wikipedia.org)
  • Not even prescription medicines can kill the leeches' eggs. (jbl.de)

  • These large leeches ( up to 5cm long) attach themselves to the fish skin, suck blood and afterwards cause bacterial and fungal infections. (jbl.de)
  • The bath removes the leeches from the fish. (jbl.de)
  • Moreover, it is now well-understood that leeches produce a pharmacological cocktail of protease inhibitors that assist the leech both in terms of successful feeding and in preventing the bloodmeal from coagulating during the extended periods in which it must reside in the crop. (amnh.org)
