Blue striped grunt of this fish. Blue striped grunts are also valued as a specimen for public aquariums. Blue striped grunt The blue striped grunt ("Haemulon sciurus") or bluestriped grunt, is a subtropical species of grunt native to the western Atlantic Ocean. It was described by the English naturalist George Shaw in 1803. Its common name comes from its blue stripes and from its habit of grunting by grinding its pharyngeal teeth. The swim bladder, acting as a resonator, amplifies this sound. The blue striped grunt commonly grows to a length of 20 to 25 cm (8 to 10 inches), and its maximum
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
