Researchers at the University of British Columbia (UBC) discovered that some fish have learnt to stay within marine reserves where they are safe from fishing, demonstrating the importance of such facilities. They made the discovery after modelling the movements of skipjack and bluefin tuna and great white sharks in the ocean.

We spend good money on quality dive gear and prudently have it frequently serviced and maintained, as this equipment will be sustaining our lives while underwater. But what about when we are on the surface? Just how many of us really do think about getting lost at sea?
