Resumen:
This study analyzed mtDNA sequences of two bottlenose dolphin subspecies found along the northernPatagonian coast, Argentina: the endangered Tursiops truncatus gephyreus and the data deficient Tursiopstruncatus truncatus. Three haplotypes were recovered from nine samples. The most frequent haplotyperepresented the coastal morph, also two haplotypes showing falcate dorsal fin, a characteristic describing theoceanic morph. This finding suggests that both morphs may exist in sympatry in Argentina. Furthermore,sampling was extended beyond the species´ previously known range, including individuals as far as sevenhundred kilometers to the south. Therefore, new genetic data, despite being preliminary, hint at anunexpectedly higher genetic diversity of matrilines than previously anticipated.
