Alonnisos Marine Park ("Larus cacchinans"), and, nesting among the rocks, the "Apus capus" and "Apus melba", the rock nuthatch ("Sitta neumayeri"), etc. The existing flora also favours the presence of species of the family Sylvidae, e.g. the Sardinian warbler ("Sylvia melanocephala") and the blackcap ("Sylvia atricapilla"). Underwater fauna is also varied, with many benthic and fish species. Various species of dolphins and some whale species may be seen in the region, such as the common dolphin ("Delphinus delphis"), the striped dolphin ("Stenella coeruleoalba"), the bottlenose dolphin ("Tursiops truncatus"), the long-finned pilot whale ("Globicephala melas"), the sperm whale ("Physeter macrocephalus") and the Cuvier's beaked
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
