Only a few marine invertebrate colonists are known, but importantly include: Sphaeroma walkeri (Crustacea: Isopoda), Ciona intestinalis (Ascidiacea: Cionidae), Crepidula onyx (Gastropoda: Calyptraeidae), Bugula californica (Ectoprocta: Bugulidae), Mytilopsis sallei (Bivalvia: Dreissenidae), Mytilus galloprovincialis (Bivalvia: Mytilidae). None of the above was recorded from Hong Kong prior to 1970 and estimates of arrival times are: S. walkeri (~1972); C. intestinalis (~1972), C. onyx (~1975); B. californica (~1978); M. sallei (~1980) and M. galloprovincialis (~1981). All are sessile biofoulers and have been introduced into Asian waters elsewhere, notably Japan. The origins and colonisation routes of these invaders are discussed in relation to the economic growth of Hong Kong and its changing patterns of trade with major trading partners over the past 35 years.
