dc.description.abstract Expanded polystyrene (EPS) is one of the major components of marine debris globally. FloatingEPS buoy as marine debris has become a habitat for marine organisms. Lugworm is a marineorganism generally found in mud and rock. Interestingly, many burrows of this specie werefound inside EPS buoy from Geoje, South Korea. In this study, ingestion and formation ofmicro-EPS particles by boring activity of lugworm was identified. Lugworms (n=10) sampledfrom EPS buoy were kept separately for 3day for collection of feces. Huge amount of EPSparticles (132±121 EPS particles/individual) were detected in feces of lugworms. The mean sizeof EPS particles was significantly correlated with the size of lugworms. To verify the formationof micro-EPS particles through burrowing activities by lugworm, two different sizes oflugworms collected from EPS buoy were kept separately in beaker filled with seawater and EPSblock for 10 days. The large-sized lugworm (1600 particles/day) created 4 times more micro-EPS particles than small-sized lugworm (390 particles/day). The mean and maximum lengths(longest axis of EPS particles) of EPS particles produced by two lugworms were 1.11 mm and 5mm for large-sized lugworm, and 0.74 mm and 3mm for small-sized lugworm. The maximumsize of the particles matched well with the mouth size of each lugworm. The size distribution ofEPS particles egested from lugworms was very similar to , many burrows of this specie werefound inside EPS buoy from Geoje, South Korea.
