Rhithropanopeus harrisii
Taxonomic Group: Crustaceans-Crabs
Common name: HARRIS MUD CRAB

Overview:

Rhithropanopeus harrisii, the Harris Mud Crab, is native to the Northwestern Atlantic, ranging from the Gulf of St. Lawrence to Veracruz, Mexico. It has been introduced to the Western United States, being found in San Francisco Bay, California and Coos and Yaquina Bays in Oregon. It has also been introduced to  Europe, Venezuela, Brazil, the Pacific coast of Panama, and Japan. This crab survives in a wide range of salinities and a variety of habitats, but it requires shelter in the form of logs, crevices or vegetation. It has likely spread through ballast water or ship fouling on commercial vessels, or through accidental transfer with oyster cultures. Although it is a successful invader in many parts of the world, its impacts have not been studied throughout much of its introduced range.
