- Lampreys are primitive jawless fish that have been in existence for over 360 million years, making them one of the oldest vertebrate species on Earth.
- Unlike most fish, lampreys do not have jaws or scales. Instead, they have a round, sucker-like mouth lined with sharp teeth, which they use to attach themselves to other fish and feed on their blood and body fluids.
- Lampreys have a unique life cycle that involves a metamorphosis from larvae to adults. They typically spend several years as filter-feeding larvae in freshwater before transforming into parasitic adults that migrate to the ocean or large bodies of water to reproduce.

Interesting Facts About Lamprey
Here are some interesting facts about lamprey:
- The Great Lakes face the challenge of an invasive species known as sea lampreys.
- Similar to sharks, sea lampreys lack skeletal bones.
- Sea lampreys are born without eyes, fins, and teeth.

Evolution and Origins of Lamprey
Sea lampreys are naturally found in the Atlantic Ocean, as well as Lake Ontario and the St. Lawrence River.
However, they expanded their presence to the remaining Great Lakes by utilizing man-made canals that circumvented natural obstacles. Their presence was officially documented in Lake Erie in 1921, Lake Michigan in 1936, Lake Huron in 1937, and Lake Superior in 1938.
Lampreys, with their ancient origins, have persevered for an impressive span of 360 million years, surviving through four significant extinction events.
Despite their remarkable resilience, the evolutionary history of lampreys remains elusive and enigmatic.
