Heart chambers are in a lamprey?
A lamprey has two heart chambers: one atrium and one ventricle. The blood flows in a single circuit through these chambers and is pumped through the body by the ventricle.
Do pacific lamprey kill fish?
Pacific lamprey are not typically known to kill fish. They are parasitic feeders that attach themselves to other fish to feed on their bodily fluids. While this parasitic behavior may weaken the host fish, it is not common for the lamprey to directly kill the host fish.
Could the sea lamprey have a major impact on the trout population in the Great Lakes?
Absolutely. As an invasive species, the lamprey has no natural enemies, and the fish of the Great Lakes have no defenses against them.
What do sea lamprey look like?
They look like eels.
How do sea lamprey cause a problem?
Sea lamprey are a problem because they are parasitic fish that attach themselves to other fish by using their suction-cup like mouths to draw blood and body fluids. This weakens and can even kill the host fish, which can have negative impacts on fish populations and ecosystems.
