The colonial tunicate Clavelina lepadiformis is a recent invader to the northwest Atlantic and has the potential to cause ecological andeconomic harm. This paper provides a review of the biological and ecological characteristics of C. lepadiformis, and hypothesizes the likelymechanisms of introduction, establishment and future expansion. The intent of this paper is to provide a consolidated source of informationfor marine ecosystem managers and provide a starting point for developing a management strategy, should one be desired. Although C.lepadiformis is not currently a management challenge because of the limited range of the invasion in North America; the similarities between C. lepadiformis and other tunicate invaders, and the proximity of incipient populations to boating, shipping, aquaculture, and energyinfrastructure suggest future economic burden of this new invader. Other regions such as the west coast of North America and New Zealandmay be at risk for invasion by C. lepadiformis.
