Lampreys Fishes

Lampreys are jawless fishes.
1.What areas they live?Sea Lamprey are found throughout the Great Lakes and clear, cold streams in the region(between Lake Ontario and Lake Erie).

2.What do they eat? How they eat?lampreys eat small critter like worms and organisms.Lamprey use their disc-shaped mouth, full of teeth, to bit onto fish. They make holes in the sides of their victims and feed on blood and body fluids. They can stay attached for hours, days, or even weeks on one fish. Large fish will most likely survive a lamprey attack with just a circular scar left on the fish's side. Small fish may die immediately from the attack or will die from an infection from the lamprey attach.

3.How they breathe? Fish are generally scaled and respire by passing water over gills.

4.How they reproduce? Lampreys begin life as burrowing, freshwater larvae (ammocoetes). At this stage, they are toothless, have rudimentary eyes, and feed on microorganisms. After several years, they transform into adults and typically move into the sea to begin a parasitic life, attaching to a fish by their mouths and feeding on the blood and tissues of the host. To reproduce, lampreys return to freshwater, build a nest, then spawn (lay their eggs) and die.
