Southwest Florida boaters may recognize FB25 because of her very distinctive dorsal fin with a series of notches toward its tip. She frequents the Intracoastal Waterway (ICW) east of Siesta and Casey Keys. This dolphin has been observed by our survey team more than 840 times since June 1984.
Over the years, we’ve seen her with nine calves; the first was a female born in 1988 that was observed until 1990 and the most recent was born in 2014 and was only observed once before it died. After that calf’s death, FB25’s eighth calf — born in 2011, known as C258 and believed to be a male — returned to her side.
FB25 is the mother of Bill, a dolphin we rescued from a crab trap entanglement in 2016. She’s also mom to Nellie (her seventh calf). Nellie was just 9 months old in 2010 when she was spotted with line encircling her neck. Fortunately, we were able to free her of the entanglement and she’s alive and well today.
FB25’s second calf, a female, was born in 1993 and was observed until 2002. This calf was FB25’s only female calf to be observed into its reproductive years.
