“…This method has been efficient for identification of several cetacean species (Tsai et al, 2013;Chang et al, 2014;Cypriano-Souza et al, 2016). However, there have been cases in which the Folmer region was not useful for differentiating Delphinus delphis, D. capensis, Stenella coeruleoalba, S. frontalis, and Tursiops truncatus, all of which are species in the family Delphinidae, more specifically in the subfamily Delphininae (Amaral et al, 2007;Viricel and Rosel, 2012;Alfonsi et al, 2013). Therefore, researchers frequently use more than one gene region for species identification (Amaral et al, 2007;Viricel and Rosel, 2012;Alfonsi et al, 2013;Cypriano-Souza et al, 2016).…”
