The U.S.V.I is home to 386 square miles of coral reefs, which is more than twice the archipelago’s total landmass and is a critical habitat for hundreds of tropical fish species and coral species. The coral reefs also provide habitat for mollusks, sea urchins, sea fans, sea anemones and sponges. Some of the coral species found here are the elkhorn coral, brain coral, pillar coral, staghorn
Round goby invasive nematode "Anguillicoloides crassus". In the Vistula Lagoon, the most abundant parasites of the round goby are nematodes "Hysterothylacium aduncum" and "Anguillicoloides crassus". 25 species of parasites are noted in the round goby in the Great Lakes. The trematode "D. spathaceum" is most abundant core species overall. Also the cestode "Proteocephalus" sp. and the trematode "Neochasmus umbellus" are rather abundant. The round goby may circumvent more of the metacercariae of "N. umbellus" from completing their life cycle. The parasite “load” on the invasive gobies in the Great Lakes appears relatively low in comparison with their native habitats, lending support to
