Habitat. Intertidal to subtidal (42 m, Bastida-Zavala & Salazar-Vallejo 2000a). Some specimens were collected from anthropogenic substrates in marinas (from La Paz, Baja California Sur, and from Huatulco and Salina Cruz , Oaxaca), as hull fouling, with salinity range of 30–36 PSU; also in brackish-water lagoons on mangrove roots; in marine water on rock bottoms, dead coral Pocillopora verrucosa , sabellariid colonies, hydrozoa Pennaria , and on Pteria and oysters shells (Bastida-Zavala 2008). Fouling species.

Distribution. Native in Tropical Pacific America. Baja California Sur ( México) to Perú ( Rioja 1941b; Rioja 1942; Bastida-Zavala 1993). It also was recorded from Brazil ( Zibrowius 1970), the Gulf of Mexico ( Rioja 1946; Bastida-Zavala & Salazar-Vallejo 2000a), Sydney ( Lewis et al. 2006) and Hawaii (Bastida-Zavala 2008), where it should be considered to be an exotic species.

Remarks. Spirobranchus minutus was found both on natural and anthropogenic substrates. It is a fouling species with potential to be introduced to other tropical regions by ships. We suspect that its presence in the Tropical Western Atlantic represent an historical introduction as fouling via ships, because it is recorded from few sites, some related to ports or fouling plates: Veracruz Port ( Rioja 1946), Cazones, Veracruz (river mouth, collected in 1981), Campeche Bank (oil platforms, collected in 1989), São Sebastião and Ubatuba, Brazil (collected in 1961– 1962) ( Zibrowius 1970; Bastida-Zavala & Salazar-Vallejo 2000a) and the northern of Gulf of Mexico (from fouling plates in ports, collected between 1999-2005, Bastida-Zavala et al., unpublished data).

An alternative hypothesis is that the species has a true Amphiamerican distribution, considering the Recent and fossil (Pliocene and Pleistocene) records of Spirobranchus minutus from northern Venezuela ( Weisbord 1962; 1964), the species may have had a free genetic flux between the eastern Pacific and Caribbean populations when the Isthmus of Panamá had not yet been formed (3.5 million years ago). Whether or not populations of both Tropical American coasts are the same can only be decided by a DNA analysis.

In 1990, ten Hove identified several adult specimens of Spirobranchus minutus (co-occurring with Hydroides brachyacantha ), scraped from the tall ship “Gorch Fock” that arrived in Sydney Harbor after an almost three weeks stay in Acapulco, Guerrero (in: Lewis et al. 2006: 669). Bastida-Zavala (2008) recorded this species in Hawaii from the hull of a sailboat too, after of a four-month voyage from San Francisco, Los Angeles, México to Hilo and Honolulu, Hawaii.
