The Levantine Basin (LB) is still considered a void as regards its cetacean fauna: species population abundance
and distribution patterns are unknown, and even the list of species and their regional status have so far not been finalized.
In an effort to fill the knowledge gap, we present original data collected in the LB over the years 1993-2009. The data
relies on strandings, bycatch victims and on incidental and dedicated-survey sightings. We supplement these by reviewing
available information on cetacean occurrence in the LB, prior to and including the above period. We believe that the
following list and suggested status is a comprehensive updated regional inventory: Species with a ‘regular’ status include
the common bottlenose dolphin, striped dolphin, common dolphin, Risso's dolphin and rough-toothed dolphin, as well as
Cuvier's beaked whale; ‘visitors’ include false killer whale, sperm whale, minke whale and fin whale; Indo-Pacific
humpback dolphin, humpback whale and killer whale are designated ‘vagrants’. The only common Mediterranean species
notably absent is the long-finned pilot whale. Indeed, despite its profound oligotrophicity, the diversity of cetacean species
in the LB equals that in the western basins, and due to the relatively lower anthropogenic impact that it sustains, it should
receive its share of resources and efforts towards conserving this diversity.
