1st Record: Island Yacht Anchorage, Los Angeles/CA/Los Angeles Harbor (2000, Cohen et al. 2002) "Four specimens of Ficopomatus enigmaticus (3 living specimens and 1 empty tube) were collected from a small boat marina in Los Angeles Harbor in August and September 2000. It is not yet known if it is established there, and no other records are known from southern California." (Cohen 2005, Exotics Guide). A collection of 86 specimens in Newport Bay in 2011 (California Department of Fish and Wildlife 2014) indicates that F. enigmaticus is established in Southern California. A record from San Diego Bay (2000, Bastida-Zavala 2008) was erroneous(Bastida- Zavala, pers. comm., 10 November 2015, cited by Pernet et al. 2016).
