The Cabras lagoon is a large and shallow transitional system (area 22 km2, mean water depth 1.7 m) which periodically suffers from dystrophic events leading to massive losses of its biological resources. In this study, we aimed to investigate the composition and seasonal distribution of macrozoobenthos. Opportunistic taxa, such as Hydrobia sp., Capitella cfr: capitata, Neanthes succinea and Ostracoda nc., typical of organic-rich environments, are dominant in the Cabras lagoon. Strong seasonal changes of macrofaunal assemblages are observed with a slight recovery during winter-spring, but a regression to an early stage of faunal succession in late-summer.
