Well here is one stiff who could manage to become the first immortal if technology can finally pin the death on something apart from the freezing cold and loss of blood.
The mechanisms of shelf-sea fronts are poorly understood. As a front passes, how do plankton and their consumers contribute to the ecology of sea and land nearby? Many species of predator specialise in visiting these fronts, whether transient or fixed, and using the warmer temperatures, the varying productivity and the food supply that gannets find a valuable diet during the breeding season.
