Habitat.Intertidal to subtidal ( 5 m, Bastida-Zavala & ten Hove2002). Onanthropogenic substrates in marinas and ports (from CaboSan Lucas and San Josédel Cabo, Baja CaliforniaSur; Puerto San Carlos, Sonora; and Salina Cruz, Oaxaca). Onrocks, floats and piers, salinity range 19–37 PSU(Bastida-Zavala & ten Hove2003). Foulingspecies.
Distribution.Caribbean Sea, Gulf of Mexico, from Eastern Floridato French Guyana. As exotic species in the Pacific side of Panamá(Bastida-Zavala & ten Hove 2002), Oaxaca(Bastida-Zavala & ten Hove 2003), Gulf of California(Tovar-Hernández et al. 2012), Hawaii( Long 1974), northern Australiaand Singapore( Lewis et al. 2006).
Remarks.The first record of Hydroides sanctaecrucisin the Tropical Eastern Pacificwas from Panamá, specimens collected in 1972 (Bastida-Zavala & ten Hove2002); previously, the species was reported from Oahu, Hawaii, collected 1968–1972( Long 1974). The species was recorded from Oaxaca, collected in 2000 (Bastida- Zavala & ten Hove2003); from Northern Australia, collected between 1998 and 2001; from Singapore, sampled 2002 ( Lewis et al. 2006), moreover, these authors suspect that H.cf. uncinata, as recorded by Sun & Yang (2000, Figs 7J-L)from the China Sea, might be H. sanctaecrucis; and from Darwin, NorthernTerritoryof Australiain 2014 (Sun et al. 2015). Recently, the species was recorded from several localities in the Gulf of California(Tovar- Hernández et al. 2012). In Northern Australia and Singapore Hydroides sanctaecrucisis an invasive species which reaches high abundances in several areas ( Lewis et al. 2006). Although the species has been present in Oaxaca and Los Cabos marinas for several years, its abundance is not very high, approximately 25–50 specimens/m2. Lakshmana Rao (1969: 9, Plate 6, Figs A–H) described Hydroides vizagensis Lakshmana Rao, 1969from Visakhapatnam, northeastern of India; however, the description and the figure of the operculum correspond to the H. sanctaecrucisdescription (opinion shared with Lena Kupriyanova and Harry ten Hove, pers. comm. 2016). Would need revise the type specimens (deposited in Andhra University, India) for confirm that suspicion.
