400-year-old Greenland shark ‘longest-living vertebrate’

For those interested in how they know how old it is, a reporter was invited to her birthday party. 🙂

“The Greenland shark’s eye lens is composed of a specialised material – and it contains proteins that are metabolically inert,” explained Mr Neilson.

“Which means after the proteins have been synthesised in the body, they are not renewed any more. So we can isolate the tissue that formed when the shark was a pup, and do radiocarbon dating.”
