21. Spinner Dolphin Stenella longirostris French: Dauphin a long bec / German: Spinnerdelfin / Spanish: Delfin girador Other common names: Long-beaked Dolphin, Long-snouted Dolphin, Pantropical Spinner Dolphin, Spinner; Gray's Spinner Dolphin (longirostris); Central American Spinner Dolphin (centroamericana); Eastern Spinner Dolphin (orientalis); Dwarf Spinner Dolphin (roseiventris) Taxonomy. Delphinus longirostris Gray, 1828, no type locality given. Later designated by J. E. Gray in 1850 to “Inhab. Southern Ocean.” Taxonomy of Stenella is currently in dispute. The genus is likely polyphyletic and will probably be revised in the near future. According to molecular studies, S. frontalis is most closely related to S. coeruleoalba and S. clymene, followed by Delphinus and Tursiops aduncus. These species appear to be more closely related to each other than any of them are to 7. truncatus, S. attenuata, or S. longurostris. Similarities in appearance between S. attenuata and S. frontalis are thus likely due to homoplasy or pleisiomorphy. If these relationships are confirmed, taxonomic assignment of these species will need to be revised. Four subspecies recognized. Subspecies and Distribution.
