At the two sites, severalresearch observatories have been run: OnDE, NEMO-SN1, SMO, KM3NeT-Italia most of them jointly operatedbetween INFN and INGV. In all these observatories, passive acoustic sensors (hydrophones) have been installed.Passive Acoustics Monitoring (PAM) is nowadays the main tool of the bioacoustics to study marine mammals.In particular, receiving the sounds emitted by cetaceans from a multi-hydrophones array installed in a cabledseafloor observatory, a research about the ecological dynamics of the species may be performed. Data acquiredwith the hydrophones installed aboard the OnDE, SMO and KM3NeT-Italia observatories will be reported. Thanksto acquired data, the acoustic presence of the sperm whales was assessed and studied for several years (2005:2013).An “ad hoc” algorithm was also developed to allow the automatic identification of the “clicks” emitted by the spermwhales and measure the size of detected animals. According to the results obtained, the sperm whale populationin the area is well-distributed in size, sex and sexual maturity. Although specimens more than 14 meters of length(old males) seem to be absent.
