Torpedo mackayana
Descrizione della specie da Wikipedia in inglese descrizione completa
Taxonomy Torpedo mackayana was described in 1919 by Jan Metzelaar (1891–1929), a Dutch biologist.
Etymology The fish was named in honor of Donald Jacob Baron Mackay (1839-1921), the then colonial administrator and governor in India; he was one of the promoters of the 1904-1905 expedition that collected the type specimen in the Dutch West Indies.
Description Torpedo mackayana has a round, "fleshy" disc, which has a slightly greater width than length. It has a gray-brown or rusty-brown upperside and a white underside. It is covered with small patches of brown or white. These patches may differ significantly in size and distribution throughout its body. It has a long, strong tail and two dorsal fins. The first dorsal fin is broad, while the second is slightly smaller and more slender.
