Carlo Gemmellaro was an Italian naturalist and geologist.
 As volcanologist he studied Etna in Sicily; his studies are summarized in the monograph "Vulcanologia dell'Etna 1859-1860" which is certainly the most mature product of the Gemmellaro research, synthesis of observations carried for decades and successful attempt of a modern volcanic theory.
 His last opera, "Un addio al maggior vulcano d'Europa" ("A farewell to the greatest volcano in Europe") as well as a brief autobiography, is also an emotional farewell to the main object of his scientific studies.
The Andalusian hound (Spanish: "Podenco andaluz" ) is a dog breed originating in Spain, especially Andalusia.
 These dogs are similar to other Iberian breeds such as the Ibizan Hound, the Portuguese Podengo, the Podenco Canario and the Maneto.
 In the Iberian Peninsula there are cave paintings representing dogs with a strong resemblance to these races.
 Dogs very similar to these, including the Cirneco dell'Etna and Pharaoh Hound, have been bred in much of the Mediterranean basin since ancient times.
 Despite the widespread belief that the podencos were introduced into Spain some 3,000 years ago by the Phoenicians, recent genetic studies have concluded that these dogs actually have a close genetic relationship with other European hunting dogs and are no more "primitive" than the others.
The Nero Siciliano is a breed of domestic pig from the Mediterranean island of Sicily, in southern Italy.
 It is raised mainly in the province of Messina, particularly in the Monti Nebrodi.

The Cilentana Grigia is an indigenous breed of domestic goat from the province of Salerno, in Campania in southern Italy.

 It is one of three indigenous goat breeds in the Cilento, the others being the Cilentana Fulva and the Cilentana Nera.
 The Cilentana Grigia is found on lower ground and richer pasture than the Cilentana Nera, and is raised mainly for milk.
 The origins of the breed are obscure; it shows the influence of the Maltese and Garganica breeds, and similarities to other Italian grey breeds such as the Ciociara Grigia of Lazio and the Argentata dell'Etna from Sicily.
The Welsh Grey or Old Welsh Grey was a breed of sheepdog native to Wales.
 It is probably now extinct, although it may have contributed to the makeup of the Welsh Sheepdog.
The Argentata dell'Etna is an indigenous breed of domestic goat from the area of Mount Etna in the province of Catania and the Monti Peloritani in the province of Messina, in the Mediterranean island of Sicily, in southern Italy.
 It is raised mainly in that area, but also in the provinces of Enna and Palermo.
 It is named for the volcano and for its silvery grey coat.

 It is the smallest of the Mediterranean island hunting hounds, the others being the Pharaoh Hounds and Ibizan Hounds.
The Himalayan Sheepdog, also referred to as the Bhote Kukur or Bhotia, is a livestock guardian dog that originated from Nepal.
 This mountain dog breed is closely similar to Indian Mastiff and the Tibetan Mastiff and may be related to the long-haired Kinnaur Sheepdog of Tibet.

 As a powerful and robust breed, the Himalayan Sheepdog is mainly used for herding purposes.
 The Himalayan Sheepdog is regionally popular as both a loyal companion as well as a working dog.
