The burrowing isopod, Sphaeroma quoianum, invades estuarine environments and causes increased erosion rates as well as significant damage to maritime structures. The reproductive patterns, high densities, and rapid colonisation rates make Sphaeroma quoianum a significant invasive species to local estuarine systems. When densities of Sphaeroma quoianum are high this isopod has the ability to increase erosion amounts up to 240%, as is the case in California.
