Yes, scientists believe that some Greenland sharks alive today are indeed hundreds of years old, with studies estimating the oldest individual to be around 400 years old (born ~1620) and still swimming in the deep North Atlantic, making them the longest-living vertebrates on Earth, though specific individuals' ages have ranges.

Why is Greenland shark toxic?

Greenland shark flesh is toxic because its meat has extremely high levels of urea and trimethylamine N-oxide (TMAO), chemicals that act as antifreeze in its deep, cold habitat but cause severe inebriation, paralysis, or even death if eaten fresh by humans and other mammals. To make it edible, a lengthy fermentation and drying process (creating hákarl) is needed to break down these compounds, making it a pungent but safe delicacy in Iceland.
