At the time of her death in 2017, Nicklo was 67 — making her the oldest documented wild dolphin in the world. During the existence of our research program — which we began 20 years after she was born — we sighted her more than 820 times. Our last confirmed sighting of Nicklo was in 2017 and she is presumed to be deceased.
We know that Nicklo gave birth to at least four calves during her life, including her last calf, Eve, which was born when Nicklo was 48. Eve gave birth to her own calf, F286, in 2012.
As with most of our long-lived Sarasota Bay residents, Nicklo’s life highlights that the bay is the dolphins’ home over many decades and across multiple generations. It’s also interesting to think about what she has seen over her lifetime, especially changes in coastal development and boat traffic.
