The Life of a Lamprey
Lamprey Dissection Pre-Ap Biology March 11, 2014 - GUZMAN
Lampreys (sometimes also called lamprey eels) are an order of jawless fish. They belong to the kingdom Animalia under the phylum Chordata and subphylum Cephalochordata. The adult is characterized by a toothed, funnel-like sucking mouth which can be highly parasitic to many fish species . The common name "lamprey" is probably derived from Latin lampetra, which may mean "stone licker."
While lampreys are well known for those species which bore into the flesh of other fish to suck their blood, most species of lampreys are not parasitic and never feed on other fish. The lampreys are a very ancient lineage of vertebrates, though their exact relationship to hagfishes and jawed vertebrates is still a matter of dispute.
Lamprey Life Cycle
Lamprey are known for their parasitic relationship with many organisms, but go through different feeding stages as juveniles and adults.
Lamprey are aquatic creatures. Many lamprey can live in freshwater such as lakes, ponds, and rivers. Some lamprey can also live in oceanic habitats. Lamprey coloration allow them to blend in with the surrounding rocks and soil found on many river beds.
Lamprey have few predators, but one example is a lake trout which is much larger than the typical lamprey size.
