Can sharks live for over 400 years?

According to a study, some sharks do that - they are the Greenland sharks.  They can live for years without tumours. This is a case of intelligent design that keeps them alive.

Death came to the world following Adam and Eves strategy in the Garden of Eden, from which they were exiled and were subject to death, and also animals died.  

A genomic study may have revealed how Greenland sharks live for centuries and yet rarely get cancer.

These sharks (Somniosus microcephalus) are slow-moving dwellers of the deep that can reach more than 6 metres long and weigh over a tonne. We know little about their lives because they roam in dark, cold waters, but it is thought they don’t reach sexual maturity until they are 150 years old and their lifespan has been estimated at about 400 years, making them the longest-living vertebrates that we know of.
