Aggressive Canadian Crabs Invading US Waters from Nova Scotia Threaten Coastal Ecosystem

BIDDEFORD, Maine (AP) The Canadian stereotype is that they are friends. But this is not the case for the crisp Canadian invaders heading for the waters of Maine.

A researcher at the University of New England has said that green crabs from Nova Scotia are older and more angry than their cousins ​​in the Gulf of Maine.

They are the same species and are alike. But the new ones are stronger. Instead of shrinking from a threat, they wave their pincers and attack.

Professor Markus Frederich said that angry invaders are likely to accelerate damage to the coastal ecosystem by engulfing clams and destroying native grasses. He is conducting research to try to understand why newcomers are so aggressive.
