Dolphins are air-breathing mammals, this means that about 99.9% of the time, when they surface to breathe, their dorsal fin is visible. For our photo-identification efforts, this makes capturing a photo of a fin relatively easy. Let’s consider, however, how one would identify bottlenose dolphins if a dorsal fin was not visible.
We have been gearing up for the arrival of new dolphin calves into our study area. We are excited to announce the birth of Bundle’s second calf!
One of the most challenging aspects of dorsal identification is positively identifying a fin over time as changed markings to the fin can make a dolphin look, sometimes, significantly different. While some fins are dramatically changed, others are more subtle.
This month we have some exciting information to share! We recently obtained some very interesting historical facts regarding one of the wild dolphins identified in our study as “Peanut.”
