The 400 year old dying shark found by researchers had roughly 400 year old Swedish coins lodged into its digestive system.
It is common to catch 200 year old sharks. Maybe 200 years ago there was exceptionally good breeding season for sharks since so many are 200 years old in a species that was proven to live twice longer than that.
>They can produce offspring even at age 100.This shark has poisonous meat which can only be eaten by Eskimos after careful preparation; meat needs to be put in underground hole and left rot for a few weeks before eating.
