Which was the last of the Great Lakes to be colonized by sea lampreys?
A) Lake Ontario
B) Lake Superior
C) Lake Huron
D) Lake Michigan
E) Lake Erie

Accepted Answer

Lake Superior was the last of the Great Lakes to be colonized by sea lampreys. This invasion was facilitated by the construction of shipping canals and the improvement of natural waterways, which allowed sea lampreys to bypass natural barriers and spread to all the Great Lakes by the 1930s and 1940s.
