The Asian shore crab is threatening shellfish from Maine to North
Carolina. It's spread fast since 1988.
Native to the western North Pacific
Ocean, this crab reached New Jersey in 1988, probably in ship ballast
water. Has now reached from Maine to North Carolina. Carapace (body
shell) is about 1.5 inches (35mm) across, squarish and mottled green,
purple or brown. Grows in intertidal zone, hides under rocks, preys
on native shellfish.
Clawed and considered aggressive. Could displace existing crab
population. May outcompete lobsters, mussels and crabs. Report crab
Call this invader a real pig.
