A European green crab (Carcinus maenas, meaning “raving mad crab”) found earlier in Willapa Bay, Washington.

Earlier this week in Westcott Bay, San Juan Island, a team of volunteer monitors caught an invasive green crab, marking the first confirmation of this global invader in Washington’s inland waters.

The volunteers are part of Washington Sea Grant’s Crab Team, an early detection and monitoring program to look for European green crab (Carcinus maenas) and collect information on local marine life.

Washington Department of Fish and Wildlife is responsible for controlling aquatic invasive animals and is working closely with University of Washington-based Washington Sea Grant to determine next steps for limiting further spread of the crab.
