European green crabs are an invasive species which have recently colonized the Northwest coast of North America, among other places. They disrupt ecosystems and prey heavily on native shellfish. However, in Europe, the population of green crabs is kept relatively low by a parasitic barnacle called Sacculina carcini. This barnacle is hardy and could likely be introduced to areas where the European green crab threatens to ruin established ecosystems.

Which of the following, if true, most strongly supports the argument that it would NOT be advisable to attempt to eliminate European green crabs from the Northwest coast of North America by introducing to the area the parasitic barnacle discussed above?
