The characteristics of Mossel Bay — calm waters, the presence of a seal population and only one cage diving company — made it a suitable venue for the study.

Sharkville represents six years of research by shark expert Ryan Johnson, and reveals much new information about these little-known animals. Amongst this include exciting footage caught on night-vision cameras in which great whites, for the very first time, were seen breaching and hunting seals at night. More than 600 hours were spent tracking the sharks. In addition, filming at night proved to be extra challenging as lights could not be used. Instead, lighting was obtained from moonlight through the use of an image intensifier.

Johnson, one of the scientists at the SA Marine Predators Laboratory (Sampla), also hosts the programme. Although there's been no news of the DVD release (yet!), the programme will be repeated on international National Geographic channels over the next five years, so do watch out for it!
