This Greenland shark is over 300 years old

*Purported to be ~300. Scientists cannot utilize vertebrae, because of its softness. They instead determine age via measuring protein spikes in their eyes, due to the proteins not decaying. They look for spikes in the protein creation that align with events such as atomic bombs. Interesting stuff.

That dude is so battleworn his teeth said fuck it we give up

This shark was alive during the napoleonic wars. Probably...
