Ecology. Ampelisca brevicornis was found in soft-bottom sediments at 5 m depth (Kocatas et al. 2001). In Vasiliko Bay A. brevicornis was found at depths of 4–13 m (7 + 3 m) mainly in sandy but also muddy sand substrates, with organic matter ranging between 1.86–7.93% (3.23 + 1.55 %), and in association with C. prolifera, C. nodosa and P. oceanica . It was found in stations classified according to the Bentix Index as in: “high” (6 stations, 39 individuals), “good” (5 stations, 41 individuals) and “moderate” (2 stations, 17 individuals). Individuals were recorded at the ports (38 individuals) and at the freshwater underwater and the power station outlet stations (9 individuals).
