The dolphins are photo identified by their dorsal fin as every fin is different. Exhibiting unique rake marks and nicks, the fin is like a finger print and in Cardigan Bay this form of identification is carried out by the SeaWatch Foundation from our vessels. There are approximately 250 identified dolphins in Cardigan Bay!
The female Bottle Nosed Dolphin can grow to approximately 3.5M with the male reaching 4.0M. They can live for up to 40 years although dolphins of 50 years have been known. The females breed every 2 to 3 years between March and September and have a gestation period of 12 months, giving birth between March and September the following year. This also coincides with the best feeding time in Cardigan Bay. The calf is usually around 1.0M to 1.30M in length at birth and will nurse from the mother for 18 months to two years. Dolphin calves do not leave the mother for up to 6 years but will usually be quite independant after about 3 years.
