2. The sea lamprey originated in the Atlantic
ocean and the Mediterranean Sea. It is older
than the dinosaurs, and is one of the last
water animals to have no jaws. It got to
Lake Ontario through the St. Lawrence
Seaway. It later escaped into the other
Great Lakes through the Welland Canal.
3. The sea lamprey looks like a snake with a
round mouth with sucking teeth circling
inside of it.
It can grow up to be 12 to 20 inches long.

4. The sea lamprey uses its teeth to eat away at
native fish in the Great Lakes, usually
tunneling through the fish.
The sea lamprey affects the economy by
bringing down the population of native fish,
such as lake trout, bourbon, and whitefish.
Doing so affects the commercial fishing in
the area.
5. One way to control the sea lamprey is to
sterilize the males, then release them so
that they can’t reproduce.
People also use chemicals called lampricides
which kill the lampreys while they are still
young.
6. So, in conclusion, you now know about the sea
lamprey, and what harm it is doing to the
Great Lakes Region. I hope that you enjoyed
this presentation. Learn more about all the
invasive species, and try to do all you can to
help!
