Tethys Research Institute north-western Mediterranean, within the waters of the Pelagos Sanctuary for Mediterranean Marine Mammals. This ongoing project focuses on the ecology and conservation of the cetacean fauna occurring in the area, which includes the fin whale ("Balaenoptera physalus"), the sperm whale ("Physeter macrocephalus"), the long-finned pilot whale ("Globicephala melas"), the Risso’s dolphin ("Grampus griseus"), the Cuvier's beaked whale ("Ziphius cavirostris"), the striped dolphin ("Stenella coeruleoalba"), the common bottlenose dolphin and, to a lesser extent, the short-beaked common dolphin ("Delphinus delphis"). The study area extends over about 24,000 km encompassing coastal, slope and deep pelagic waters between continental Italy, France and the
Delphinus Pegasus the flying horse. Delphinus lacks stars above fourth (apparent) magnitude; its brightest star is of magnitude 3.8. The main asterism in Delphinus is Job's Coffin, nearly a 45°-apex lozenge diamond of the four brightest stars: Alpha, Beta, Gamma, and Delta Delphini. Delphinus is in a rich Milky Way star field. Alpha and Beta Delphini have 19th century names Sualocin and Rotanev, read backwards: Nicolaus Venator, the Latinized name of a Palermo Observatory director, Niccolò Cacciatore (d. 1841). Alpha Delphini is a blue-white hued main sequence star of magnitude 3.8, 241 light-years from Earth. Beta Delphini, called Rotanev. The gap
