| Summary: | tional observation methods were used onboard a 12 meter motorsailer. A zig-zag sampling of 584 kilo-meters and 65 hours of observation were done, during which 21 groups of cetaceans were sighted. Five species were observed: the fin whale (3 sightings), the striped dolphin (10 sightings), the com-mon dolphin (6 sightings), the bottlenose dolphin and the sperm whale (1 sighting each). High sight-ing frequencies were obtained for the striped dolphin in the pelagic area and for the common dolphin in the slope area, suggesting that each species favours a distinct habitat. This study is in reasonable concordance with the few results already published on the subject. However more research must be done in this area. Key words: boat survey, cetaceans, sighting frequency, western Sardinia, common dolphins |
