The results of several years of benthic research in Lake Tiberias are summed up. A provisional census of the invertebrate zoobenthos reveals a relatively reduced number of species. The widespread anoxyc conditions, the oligohaline salinity, and the stormy regime of the lake are held responsible for this reduction.

Five faunal belts are recognized in the benthal of the Lake: 1) the Supralittoral; 2) the Littoral; 3) the Sublittoral; 4) the Epiprofundal and 5) the Profundal. Seasonal changes occur chiefly in the littoral during the spring, and in the profundal during the winter.

The faunal history of the Lake is analysed, and the following phases are proposed: 1) the late Pliocene marine-brackish Bira lagoon; 2) the early Pleistocene freshwater Melanopsis lake; 3) the regressive Naharayim lake; 4) the interglacial, brackish Lissan I lake; 5) the glacial transgressive freshwater Lissan II lake. For the present postglacial stage, some man-made changes in the biological equilibrium are discussed.
