Lampreys / ˈlæmpreɪz / (sometimes inaccurately called lamprey eels) are a group of jawless fish comprising the order Petromyzontiformes / ˌpɛtroʊmɪˈzɒntɪfɔːrmiːz /, sole order in the class Petromyzontida. The adult lamprey is characterized by a toothed, funnel-like sucking mouth.

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.

2024年6月16日 · Among the most primitive of all vertebrate species, the sea lamprey is a parasitic fish native to the northern and western Atlantic Ocean. Due to their similar body shapes, lampreys are sometimes inaccurately called "lamprey eels." Unlike "bony" fishes like trout, cod, and herring, lampreys lack scales, fins, and gill covers.

2021年12月1日 · The 48 described species of parasitic and non-parasitic lamprey within the order Petromyzontiformes span much of the globe. Although the sea lamprey (Petromyzon marinus) is an unwanted invasive in the Laurentian Great Lakes, most lamprey species are of ecological and cultural value, and of conservation concern.

The sea lamprey is parasitic, best known for its suction-cup mouth that allows it to attach to other fish and feed on their fluids, earning the species the nickname “vampire fish.”

Sea lampreys (Petromyzon marinus) are parasitic fish native to the Atlantic Ocean. Sea lampreys, which parasitize other fish by sucking their blood and other body fluids, have remained largely unchanged for more than 340 million years and have survived through at least four major extinction events.

The sea lamprey (Petromyzon marinus) is an aggressive parasite that is considered a pest in many regions, including the U.S. Great Lakes. An ancient vertebrate, its lineage diverged from that of humans about 500 million years ago.

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

2021年12月1日 · This paper discusses direct evidence for lamprey feeding ecology, as observed through lamprey-induced wounds on hosts and prey, and lamprey attachments on hosts and prey; and indirect evidence for feeding ecology, via analyses of fatty acids, stable isotopes, contaminants, and bioenergetics modelling.

Lampreys are parasitic fish where the development of kidneys allows them to filter freshwater, as well as saltwater, expanding their range.
