The sea lamprey (Petromyzon marinus) is a parasitic lamprey native to the Northern Hemisphere. It is sometimes referred to as the "vampire fish". In its original habitats, the sea lamprey coevolved with its hosts, and those hosts evolved a measure of resistance to the sea lampreys.
Lampreys live mostly in coastal and fresh waters and are found in most temperate regions. Some species (e.g. Geotria australis, Petromyzon marinus, and Entosphenus tridentatus) travel significant distances in the open ocean, [13] as evidenced by their lack of reproductive isolation between populations.
The Pacific lamprey (Entosphenus tridentatus) is an anadromous parasitic lamprey from the Pacific Coast of North America and Asia in an area called the Pacific Rim. [4] It is a member of the Petromyzontidae family. The Pacific lamprey is also known as the three-tooth lamprey and tridentate lamprey. Ammocoetes held by biologist in the Carmel River
Each larva that grows into a juvenile sea lamprey will migrate into Lake Michigan and can kill 40 pounds of fish in its 12- to 18-month feeding period.
Petromyzontidae are a family of lampreys native to the Northern Hemisphere, comprising the vast majority of living lampreys. [1] Petromyzontids have the highest number of chromosomes (164–174) among vertebrates.
Long Island Sound is a large marine estuary in the Northeastern United States. It forms the maritime border between the states of New York and Connecticut.It is diverse and serves as a breeding ground to many different types of marine animal species; the following is a list of said species by scientific and/or common name.
Lampreys form a superclass containing 38 known extant species of jawless fish. [3] The adult lamprey is characterized by a toothed, funnel-like sucking mouth. Although they are well known for boring into the flesh of other fish to suck their blood, [4] only 18 species of lampreys are actually parasitic. [5]
Cyclostomi, often referred to as Cyclostomata / s ɪ k l oʊ ˈ s t ɒ m ə t ə /, is a group of vertebrates that comprises the living jawless fishes: the lampreys and hagfishes.Both groups have jawless mouths with horny epidermal structures that function as teeth called ceratodontes, and branchial arches that are internally positioned instead of external as in the related jawed fishes.
