Some 250 Bottlenose dolphins have been catalogued in the Ponta do Ouro Partial Marine Reserve as well as a handful of Humpback Dolphins.
Dolphins, like humans have a fingerprint and although sometimes we have to wait for that fingerprint to form in dolphins, each animal, as time goes by develops a unique and individualised fin.
Some dolphins however bear other useful identification markings that can be used too, like Gilly for example. For a couple of years she was only identifiable through a series of rake marks. As the years passed she developed a slight notch at the bottom of her fin and then another in the middle and then one day - her fin changed completely!
The ever changing dorsal fins; caused from wear and tear, predation, fishing line and boat interactions keep us on our toes as we try to keep track of who is who in the Reserve.
