Oaxaca: UMAR-Poly 765, 4 spec. ( Salina Cruz  , angler pier, main dock, sta. 4, 1 m, May 26, 2011, coll. SGM et al.); UMAR-Poly 766, 10 spec. (same, hull of the shrimp boat “Golfo Pérsico”, 1 m, May 26, 2011, coll. EVP): UMAR-POLY 767, 8 spec. (“sample 85”, Oaxaca, 0–6 m, September 15, 2004). 

Habitat. Intertidal to subtidal (20 m, Sun et al. 2015); deeper records, 110– 1,200 m from California ( LACM- AHF 1377, 2475, 2792, 2850), were regarded to be questionable by Bastida-Zavala (2008: 26). Most records of Hydroides elegans  were as fouling on artificial substrates: hulls of ships, terracotta and PVC panels and harbor structures. In the Hawaiian Islands it was also found on reef flats, reef slope and on the native alga Dictyosphaeria cavernosa ( Bailey-Brock 1976)  . In the material studied the specimens were associated only with anthropogenic substrates in marinas and ports from La Paz, Puerto Escondido and Santa Rosalía   , Baja California Sur, and from Salina Cruz    , Oaxaca. Fouling species. 

Distribution. Worldwide in temperate and tropical regions. Mediterranean, North Sea, Gulf of Mexico to Brazil, South Africa, Persian Gulf, India, Australia, Micronesia; California ( USA) to Oaxaca ( México), Hawaii ( Zibrowius 1971; Bastida-Zavala & ten Hove 2002; 2003; Sun et al. 2015).

Remarks. The confusion between Hydroides elegans  and H. norvegica Gunnerus, 1768  was unraveled by Zibrowius (1971), mainly on the basis of the collar chaetae: in H. norvegica  with 2–3 teeth, while they have many small teeth in H. elegans  . Hydroides norvegica  has a distribution limited to the boreal Atlantic and subtidal waters in the Mediterranean, while H. elegans  has a worldwide distribution in temperate and tropical waters, mainly in harbors and marinas ( Zibrowius 1971; ten Hove 1974; Zibrowius 1992; Kupriyanova & Jirkov 1997; Bastida- Zavala & ten Hove 2002; 2003; Moen 2006; Bastida-Zavala 2008; Ben-Eliahu & ten Hove 2011). Long (1974: 28) recorded both H. elegans  and H. norvegica  from Oahu, Hawaii; however, after the revision of Zibrowius (1971) it is uncertain if the specimens identified by Long as H. norvegica  belong to H. elegans  or a different taxon.

Zibrowius (1992) doubted if Hydroides elegans  originated from Australia; however, Ben-Eliahu & ten Hove (2011) propose that its origin probably is Australia and Sun et al. (2015) suggest on biogeographical and ecological reasons that H. elegans  is likely to be a native to Australia. Many historic and recent records of H. elegans  come from ports and marinas, on anthropogenic substrates; however, in the Hawaiian Islands the species was found in both natural sites and in boat harbors ( Long 1974; Bailey-Brock 1976); also, H. elegans  was found in Australia both in natural sites (lagoons), as well as fouling of fish farms, harbors and ship’s hulls (Sun et al. 2015).

Hydroides elegans  has been present in the Eastern Pacific for at least 86 years; its first record was Newport Bay , Southern California ( Berkeley & Berkeley 1941, as Hydroides norvegica  ); Bastida-Zavala & ten Hove (2003) recorded specimens collected in 1929 from the fouling of a submarine ( U.S. Narwhal, N-1) in the harbor of San Francisco. In the Tropical Eastern Pacific the species was recorded first by Bastida-Zavala (2008) with a sample of more than a thousand specimens encrusting (1991) a PVC plate in La Paz Bay, Baja California Sur  ; later, Tovar- Hernández et al. (2009b) recorded the species in the fouling of Mazatlán port, Sinaloa  .

Hydroides elegans  was selected as a model species for research in biofouling and testing marine coatings for a number of reasons: its high abundance and the fact that their calcareous tubes can create problems for vessels. Furthermore H. elegans  is easy to reproduce in laboratory ( Carpizo-Ituarte & Hadfield 1998; Nedved & Hadfield 2008), making it possible to experiment with different means to avoid their settlement, e.g. antifouling paints ( Johnson & Gonzalez 2004; Johnson et al. 2006); and has been observed that the larvae settle in response to both natural biofilms, formed by marine bacteria, or to artificially induced surfaces by cations and other chemicals ( Nedved & Hadfield 2008).
