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.
Louis Logan, a University of New England graduate student, had the unpleasant task of labeling the crabs captured from Nova Scotia waters for the research.
The crabs were in no mood for games. At a distance of 5 feet, the pint-sized brutes, which measure 4 to 5 inches across, assumed a fighting posture. Those that grabbed him were in no hurry to let go. "Any time I went down to grab one they went to grab me instead," he wrote in an email. One of them, in particular, would jump out of the water in its frenzy to attack.
