Invasion History in Panama:
Hydroides sanctaecrucis is native to the Caribbean coast of Panama. In 1972, it was collected at Naos Island, Panama, in the Pilot area, Panama Bay, near the Pacific end of the Panama Canal. (1972, USNM 58568, US National Museum of Natural History 2010). In 1974, it was collected in the lower chamber at the Miraflores Locks ( USNM 58569, US National Museum of Natural History 2010); It was collected in Panama Bay in 2009, and is considered established in Panama Bay (Ruiz et al. unpublished, 2010)
Invasion history elsewhere in the world:
Ships leaving the Panama Canal were the probable vector for the spread of H. sanctaecrucis into the Eastern Atlantic. Hydroides sanctaecrucis has been found at many sites in Australia, including fouling in a marina in Darwin, Northern Territory in 1998, in Cairns, Queensland in 1999, and on the hulls of naval ships and recreational vessels (Lewis et al. 2006). This polychaete has not been reported from other locations in Australia (Sun et al. 2015). Hydroides sanctaecrucis has become established in several major Asian ports, including Singapore (2002, Wells et al. 2019); Hong Kong (2009, Sun et al. 2012); and Kaohsiung, Taiwan (2015, Ferrario and Minchin 2017).
Description
Hydroides sanctaecrucis secretes a calcareous tube as do other serpulid polychaetes. The tube is smooth and white with two longitudinal ridges or none at all and lacks a peristome (raised ring around the opening) (Bastida-Zavala et al. 2017). Serpulids have a feathery crown of modified prostomial palps called radioles (the prostomium is the first segment, projecting above the mouth). There are 16 radioles each, on the right and left sides of the mouth (Bastida-Zavala et al. 2008). The radioles can be folded and withdrawn into the tube. One of the of the radioles is modified to form an operculum, which acts as a plug when the animal contracts. The peristomium (segment behind the mouth) is folded back to form a collar, which bears uniramous parapodia, with a distinctive set of collar chaetae which have spines or serrations. The collar is the first of seven thoracic chaeta-bearing segments (chaetigers). The subsequent segments have biramous parapodia. The dorsal branch of the parapodium is called the notopodium; the ventral branch is the neuropodium. Chaetae in the two branches and along the body can vary greatly in their morphology, which can be critical in the taxonomy. The operculum is supported by a cylindrical peduncle. The opercular funnel has 19-29 radii with pointed tips. The verticil has 11–14 yellowish winged spines, all curving ventrally, with pointed tips and external spinules. The collar chaetae are bayonet chaetae, with two blunt or pointed teeth and a smooth distal blade (Bastida et al. 2008; Bastida-Zavala et al. 2017). The thorax has six chaetigers bearing short, saw-shaped setae called uncinae, and limbate chaetae. The abdomen has about 94 segments (57-149, n=4). The overall length is about 20.8 mm (11–306.5 n=54). The worm is yellow to light brown. (Description from Bastida-Zavala and ten Hove 2002; Bastida-Zavala 2008; Bastida-Zavala et al. 2017).

Ecology
General:
Life History- Hydroides sanctaecrucis feeds by extending its feathery gills and trapping plankton in the water column. In most serpulid species, the sexes are separate, and larvae are planktotrophic.
Ecology- Hydroides sanctaecrucis occupies subtropical to tropical habitats, at salinities of 18–31 PSU (Bastida-Zavala and ten Hove 2002; Bastida et al. 2017). The species is known from a wide range of substrates, including 'coral, mollusk shells, seagrass, algae, sponges, rocks and artificial substrates' (Bastida-Zava et al. 2017).
