Seven Nebraska women were clocked swimming upstream in the Missouri faster than the local spotted dolphins.

Northern offshore spotted dolphins were around 40-50 per cent of their original numbers, and common dolphins about 60 per cent.

Since 1979, the spotted dolphin has suffered the highest mortality, more females being killed than males.

It lives in common waters with the pantropical spotted dolphin and the bottlenose dolphin.

The common name for species in this genus is the "spotted dolphins" or the "bridled dolphins".

The pantropical spotted dolphin varies significantly in size and colouration throughout its range.

The pantropical spotted dolphin is very active and is prone to making large, splashy leaps from the sea.

As the pantropical spotted dolphin can be divided into three subspecies, studies of these distinct populations would be needed to assess conservation efforts.

Dolphins, like the Pantropical spotted dolphin can be found in the water near the island.

Later on the same day, while on a whale-watching trip, we were surrounded by 200 or more spotted dolphins, performing unbelievable gymnastic displays.
