PHOTO ID EXAMPLE, HOW WORKS?

RISSO’S DOLPHINS (Grampus griseus)

The first serie shows the categories of dorsal fin scarification: the figure is  a composite of cropped colour pictures converted to b/w images.

the next serie shows a long term id of rissos: Indivuals S1b pinter and S2a Blunt photographed over three consecutive years (2004-2006) for both cases, patterns of marks are preserved through the years.
