Stenella

Stenella is a genus of aquatic mammals in Delphinidae, the family informally known as the oceanic dolphins.[1][2][3]

Currently, five species are recognised in this genus:[2]

The common name for species in this genus is the "spotted dolphins" or the "bridled dolphins".[1][2] They are found in temperate and tropical seas all around the world.[1][2] Individuals of several species begin their lives spotless and become steadily more covered in darker spots as they get older.[1][2]

The genus name comes from the Greek stenos meaning narrow.[1][2] It was coined by John Gray in 1866 when he intended it as a subgenus of Steno.[1] Modern taxonomists recognise two genera.[1][2]

The clymene dolphin (S. clymene) is the only confirmed case of hybrid speciation in marine mammals, descending from the spinner dolphin (S. longirostris) and the striped dolphin (S. coeruleoalba).[4]
