Stenella
''Stenella'' is a genus of marine mammals in Delphinidae, the family (biology), family informally known as the oceanic dolphins. Species Currently, five species are recognised in this genus: ''S. rayi'' was a species of this genus found in North Carolina, in the early Pliocene. The common name for species in this genus is the "spotted dolphins" or the "bridled dolphins". They are found in temperate and tropical seas all around the world. Individuals of several species begin their lives spotless and become steadily more covered in darker spots as they get older. The genus name comes from the Ancient Greek, Greek meaning narrow. It was coined by John Edward Gray, John Gray in 1866 when he intended it as a subgenus of ''Steno (genus), Steno''. Modern taxonomists recognise two genera. 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. ...

Clymene Dolphin
The Clymene dolphin (''Stenella clymene''), in older texts known as the short-snouted spinner dolphin, is a dolphin endemic to the Atlantic Ocean. It is the only confirmed case of hybrid speciation in marine mammals, descending from the spinner dolphin and the striped dolphin. Taxonomy The Clymene dolphin was first formally described by John Edward Gray in 1846, although, unusually, he did not assign it its current name until four years later, in 1850. From then on, until a reassessment in 1981, the Clymene dolphin was regarded as a subspecies of the spinner dolphin (''Stenella longirostris''). In 1981, Perrin ''et al.'' asserted the Clymene's existence as separate species. Until this time, because Clymenes are relatively remote and were regarded as very similar to the more accessible spinners, they were never heavily studied. Anatomical and behavioral traits suggested that this species is a hybrid of the spinner dolphin and striped dolphin (''Stenella coeruleoalba''), and DN ...
