Nova Scotia: Crabs and Eel Grass

nova scotia: The docile green crabs shrink from a threat, while the newcomers are more apt to wave their pincers and charge, according to CTV. What we're seeing is this insane level of aggressiveness, said Markus Frederich, a professor at the University of New England. Green crabs from Nova Scotia are the same species as their cousins that already inhabit Maine waters, but are ornerier and angrier, threatening to accelerate harm to the coastal ecosystem by gobbling up soft-shell clams and destroying native eel grass, a researcher said. They're each genetically distinct. Green crabs, even the docile ones, are considered a scourge that can devour soft-shell and juvenile clams. The new crab variant that originated in northern Europe is hardier and adapted to colder water than the more docile crab, which originally came from southern Europe. (www.immigrantscanada.com).
