• The Arctic lamprey (Lethenteron camtschaticum), also known as the Japanese river lamprey or Japanese lampern (Petromyzon japonicus Martens 1868, Lampetra fluviatilis japonica (Martens 1868), Lampetra japonica (Martens 1868), Lethenteron japonicum (Martens 1868) ), is a species of lamprey, a jawless fish in the order Petromyzontiformes.

  • Some species live in freshwater for their entire lives such as the Korean lamprey (Eudontomyzon morii), while others, including the sea lamprey (Petromyzon marinus) and the Arctic lamprey (Lethenteron camtschaticum), usually migrate to the sea to feed7. (firstpointsoftware.com)
  • The Kern brook lamprey ( Lampetra hubbsi ) is a species of lamprey in the Petromyzontidae family endemic to the United States. (eol.org)
  • The ammocoetes, as the lamprey larvae are known, are found in muddy freshwater habitats where they burrow in the mud and feed on detritus. (wikipedia.org)
  • The life cycle of all lampreys begins with a freshwater larval phase (also called ammocoetes), in which the larval lampreys live burrowed in the substrate of streams as filter feeders. (firstpointsoftware.com)
  • In the last stage, the adult lampreys return to freshwater to spawn and die7,13. (firstpointsoftware.com)

  • The genus Lampetra comprises the subgenera Entosphenus , Lethenteron , and Lampetra . (eol.org)
  • However, molecular evidence helped lead to the determination that the Kern Brook Lamprey should be under the genus Lampetra instead, as Lampetra hubbsi clustered with species from the Lampetra subgenus from the west coast of North America. (eol.org)
  • L. hubbsi was determined to have a higher fecundity in comparison to another nonparasitic lamprey species, Eudontomyzon hellenicus , also known as the Macedonia brook lamprey, which is critically endangered. (eol.org)
  • In parasitic species of lampreys, the oral disc and dagger-like tongue is used to attach to and pierce the hide of fishes to allow them to ingest blood9. (firstpointsoftware.com)
  • Forty lamprey species are currently recognized for the extant lampreys, of which 18 species are parasitic14. (firstpointsoftware.com)
  • Finally, a lamprey spatial metabolomics database (https://www.lampreydb.com) was constructed to assist studies using lampreys as animal model. (firstpointsoftware.com)
  • Accumulating fossil evidence has demonstrated that lampreys in the Devonian period were already almost identical to the modern adult lampreys, with well-developed oral disc, annular cartilages, and circumoral teeth3,4,5,6, suggesting the evolutionary long-term stability of lampreys. (firstpointsoftware.com)
  • The alternative scheme proposed that jawed vertebrates are more closely related to lampreys than to hagfish (i.e., that vertebrates include lampreys but exclude hagfish), and introduced the category craniata to group vertebrates near hagfish. (eol.org)
  • By analyzing the metabolic profiles of 14 different lamprey tissues, we show that two groups of metabolites in the buccal gland of lampreys, prostaglandins and the kynurenine pathway metabolites, can be injected into the host fish to assist lamprey blood feeding. (firstpointsoftware.com)
  • Almost all blood-sucking animals are invertebrates, such as fleas, ticks, leeches, and mosquitoes, and lampreys are one of the only a few groups of vertebrate ectoparasites15. (firstpointsoftware.com)
  • Given their unique phylogenetic position and status as one of the few groups of vertebrate ectoparasites, lampreys are expected to have developed distinct metabolites specifically adapted for blood-feeding and parasitism. (firstpointsoftware.com)
  • Finally, we have constructed a lamprey spatial metabolomics database to facilitate studies in biochemistry, clinical chemistry, natural product discovery, medicine, and metabolomics using lampreys as a model animal. (firstpointsoftware.com)
  • As such, parasitic lampreys must suppress the immune response (that can lead to itching or pain and thus trigger defensive behavior on their hosts), nociceptive response (that can initiate host defense behavior), and hemostasis (the vertebrate mechanisms that prevent blood loss) of the host to ensure successful and long-term blood feeding.

  • L. hubbsi is similar to other lampreys in that it has a thin eel body. (eol.org)
  • The Arctic lamprey (Lethenteron camtschaticum), also known as the Japanese river lamprey or Japanese lampern (Petromyzon japonicus Martens 1868, Lampetra fluviatilis japonica (Martens 1868), Lampetra japonica (Martens 1868), Lethenteron japonicum (Martens 1868) ), is a species of lamprey, a jawless fish in the order Petromyzontiformes.
