Monocorophium insidiosum
Taxonomic Group: Crustaceans-Amphipods

Overview:

Monocorophium insidiosum is a tube-building gammarid amphipod. It has a wide global distribution and its native range is currently unknown. Populations are established in temperate and sub-tropical regions on both coasts of North America, both coasts of South America, Europe, Australia, and Asia. Likely vectors for its spread include hitchhiking on the hulls of commercial ships and oyster transplants. It is found in shallow marine and estuarine waters where it builds tubes attached to hard surfaces, including rocks, bivalve shells, pilings, docks, buoys, and ships’ hulls. It can form U-shaped burrows in mud and silt. In some areas it is an abundant pest species known for fouling maritime structures, but its impacts have not been quantified on a large scale.
