From anthropogenic substrates in ports and marinas, at pier piles, boat hulls, buoys, ropes, as well as oyster and shrimp farms (Villalobos-Guerrero et al . 2012). Fouling species. Distribution. Caribbean. As exotic/invasive species in several sites from the Gulf of California ( Sinaloa , Sonora , Baja California and Baja California Sur ), Chacahua Lagoon and Salina Cruz , Oaxaca ( Tovar-Hernández & Knight-Jones 2006 ; Villalobos-Guerrero et al . 2012); Coiba Island , Panamá ( Capa & López 2004 ); Levantine Sea and Cyprus (Ҫinar 2009) and Madeira Island ( Ramalhosa et al . 2014 ). Remarks. Tovar-Hernández et al . (2009a) recorded Branchiomma bairdi for the first time from Mazatlán and around; it also was reported from some beaches in La Paz Bay , Baja California Sur ; from Guaymas and San Carlos ports, Sonora ; and from Ahome, Guasave and Topolobampo, Sinaloa (Tovar-Hernández et al . 2012). The species has a strong colonizing capacity, since it is a hermaphrodite and also due to its brief larval stage it can reach high densities starting with few specimens; thus, it is competing with local encrusting fauna for space and food resources ( Tovar-Hernández et al . 2009b ). A recent technical report and risk analysis concluded that the species is now established in some ports, marinas and beaches in the Gulf of California and should be treated as an exotic/ invasive species ( Tovar-Hernández & Yáñez-Rivera 2012a ; Villalobos-Guerrero et al . 2012).
