Age structure of strandings and growth of Lahille's bottlenose dolphin ( Tursiops truncatus gephyreus )

This study describes the age structure and sex‐specific growth patterns of Lahille's bottlenose dolphins ( Tursiops truncatus gephyreus ), a subspecies endemic to the Southwest Atlantic Ocean (SWAO). The ages of 120 animals collected in southern Brazil between 1976 and 2017 were determined. We found high frequencies of young animals, mostly males, with no sex bias among adults. A temporal change in the age structure of strandings was observed,...
