ldentifying a spinnerdolphin, Stenella longirostris (Gray, 1828), stranded in Bahia State, Brazil, using mtDNA sequences
On June 7'h 1995, a young dolphin (genus Stenella) was found dead at 5tella Mares beach (13°00'30"5; 38°27'20"W), Salvador-Bahia. Externai characteristics of this individual suggested that it should be a spinner dolphin, Stenella longirostris. However, because morphometry an...
