The site, subdivided into three subsites, is of significant importance as it includes one of the longest Posidonia meadows in Liguria, going from Albenga to the west of the port of Loano. This habitat is mainly established on ‘matte’ and it is in relatively good condition. The most degraded and fragmented area is located near the artificial barrier of the coast of Loano. There are also meadows with Cymodocea and photophilic algae biocenoses, including Sargassum, which is widely developed on the blocks of the Loano artificial barrier. Notable is the presence of Pinna nobilis, a vulnerable and threatened species in Liguria, as well as various species of wrasse, greater pipefish, and groupers.
