Risso's dolphin
Risso's dolphin is named after Antoine Risso, whose description formed the basis of the first public description of the animal, by Georges Cuvier, in 1812. Another common name for the Risso's dolphin is grampus (also the species' genus), although this common name was more often used for the orca. The etymology of the word "grampus" is unclear. It may be an agglomeration of the Latin "grandis piscis" or French "grand poisson", both meaning big fish. The specific epithet "griseus" refers to the mottled (almost scarred) grey colour of its body.
