How does a sea lamprey eat?

What is a sea lampreys prey?

Sea lampreys prey on all large Great Lakes fish species including lake trout, salmon, rainbow trout, whitefish, walleye and catfish. At the end of their parasitic phase, they undergo another, less drastic transformation in preparation to spawn and head back upstream where they die after laying their eggs.

How does a lamprey mouth work?

The juvenile sea lamprey uses its suction disk mouth which is filled with small sharp, rasping teeth and a file-like tongue to attach to fish, puncture the skin, and drain the fish's body fluids. An anticoagulant in their saliva ensures that the blood of the host fish does not clot while the sea lamprey feed.

Do sea lamprey have predators?

As with many invasive species, the sea lamprey entered the Great Lakes and found no natural predators, competitors, parasites or pathogens — no natural population controls. The top predators of the existing food web, like lake trout, were particularly susceptible to sea lamprey predation.

Do sea lamprey eat sharks?

But the Sea Lamprey is known to prey on large marine fish, including sharks.

Are lampreys blind?

Ammocoetes: Larval lamprey, called ammocoetes, are dark colored on the dorsal surface and light colored on the ventral surface. They are blind and have no teeth and filter feed on planktonic drift.

How did lampreys invade the Great Lakes?

Sea lampreys entered the Great Lakes from the Atlantic Ocean through man-made shipping canals and were first observed in Lake Ontario in the 1830s. Niagara Falls acted as a natural barrier preventing sea Lamprey movement to Lakes Erie, Huron, Michigan, and Superior.

Do lampreys attach to sharks?

Lamprey parasitism on sharks isn't exactly new, as there have been previously published accounts, but they are quite rare. This observation, coupled with those that date back to 1993, suggests that when a sea lamprey does adhere to a shark, the cloaca and that surrounding region is a common point of attachment.

How does the sea lamprey affect the ecosystem?

Fishery Impacts

Other studies found that a single sea lamprey can kill 40 or more pounds of fish during its adult life. Fish that survive a sea lamprey attack expend more energy on healing than on producing eggs and mating, causing declines in fish populations.

Can lampreys live out of water?

Not all lampreys spend time in the sea. Some are landlocked and remain in fresh water. ... Other lampreys, such as the brook lamprey (Lampetra planeri), also spend their entire lives in fresh water. They are nonparasitic, however, and do not feed after becoming adults; instead, they reproduce and die.

Who eats lamprey?

Host fishes can die from infections that develop in the wound or if more than one lamprey is attached to the same fish at the same time. Non-parasitic adults do not feed while they wait for the spring to spawn. What eats them? Larval lampreys are eaten by fish and the only predators for the adults are humans.

Do catfish eat lamprey?

We found that many sea lampreys are eaten by European catfish, and these new fish pose a serious threat to the survival of sea lampreys in their native habitat.

What is the largest predator in the Great Lakes?
