5.4.4 Bottlenose Dolphin (Tursiops truncatus)
The bottlenose dolphin are found in tropical and temperate waters worldwide and
show a high variation in morphology according to geographical location, where
adult lengths range between 2.5 and four meters approximately (Wells and Scott
2009). The distribution of bottlenose dolphins is spread along the Southwestern
Atlantic at both nearshore (coastal ecotype) and offshore (oceanic ecotype) waters
(Bastida et al. 2007). The coastal ecotype concentrates in areas near river discharge,
estuaries and bays of Argentina, Uruguay and southern Brazil (Fruet et al. 2014).
The oceanic ecotype, on the other hand, seems to be widely distributed in tropical
and subtropical deep waters along the outer continental shelf and beyond and in
association with oceanic islands (Bastida et al. 2007) (Fig. 5.15).
