Invasive 'Mitten Crab' Captured in Oregon River, Raising Alarm

Oregon wildlife officials have captured a live Chinese mitten crab in a local river. This is only the second confirmed sighting of this invasive species in the state, raising concerns about its potential spread. The crab was found and removed by hand. The species is considered highly invasive, meaning it can aggressively disrupt local ecosystems. Chinese mitten crabs are notable for their furry, mitten-like claws. They are a significant concern because they can climb over barriers as high as 13 feet (4 meters), making them difficult to contain. They also burrow into riverbanks, causing erosion. Authorities urge the public to report any sightings. If captured, people should take a photo, note the location, freeze the crab, and contact officials immediately. They warn against releasing any live crab back into the water.
