COMMON DOLPHIN
Delphinus delphis
William F. Perrin
Previous editions of this book recognized two globally distributed
species of common dolphins: the short-beaked common
dolphin Delphinus delphis and the long-beaked common dolphin
D. capensis as proposed by Heyning and Perrin (1994). However,
according to the Committee on Taxonomy [Society for Marine
Mammalogy] (2016), “… evidence that D. capensis thus considered
is a polyphyletic taxon has been accumulating for some time.
The long-beaked condition is apparently a convergent character
state induced by regional ecology. In some regions, long-beaked
common dolphins are genetically more closely related to shortbeaked
common dolphins than to long-beaked common dolphins
in other regions (e.g., see Natoli et al., 2006). Cunha et al. (2015)
summarized the relevant data and analyses, along with additional
molecular data and analysis, and recommended that D. capensis
not be further used as proposed by Heyning and Perrin (1994).”
That recommendation is followed here. Further, “Cunha et al.
(2015) noted that because the sympatric/parapatric long-beaked
and short-beaked common dolphins off California in the Eastern
North Pacific (ENP) appear not to interbreed, perhaps the ENP
long-beaked common dolphins might be recognized as a separate
species D. bairdii Dall, 1873. However, the genetic analysis for the
ENP (Rosel et al., 1994) did not include samples from the contiguous
regions to the south in the eastern tropical and eastern south
Pacific where common dolphins occur.” (Committee on Taxonomy,
2016). Pending a more complete global review and revision of the
common dolphins, the long-beaked ENP form is here considered a
subspecies D. d. bairdii. Three recognized subspecies are shown in
