In 2007 , Esquimau whalers in Alaska made a surprising find . In the carcase of a whale , they found fragment of a weapon embedded in its material body – but this was n’t a New opus of equipment . The harpoon was decipher back to the 1900s , and after investigation , scientists estimated that the whale itself was around 115 years sure-enough , if not older .
Bowhead giant ( Balaena mysticetus ) were severely affected by the introduction of widespread commercial whaling that saw their numbers plump to fewer than3,000 fellow member . It was effectively ended by 1921 , a move that has seen the population grow to between 10,000 to 23,000 individuals .
The whaling Bachelor of Arts in Nursing does n’t apply tosubsistence huntsled by Indigenous Peoples along the westerly and northern coasts of Alaska , where bowhead whale have been a vital food author for millennia . It was during one of these subsistence hunts that an strange discovery was made inside the body of a bowhead caught by Inuit whaler . According to theNew York Times , a biologist descry the fragment as the whale was being carve up and station it to a historiographer at the New Bedford Whaling Museum , John Bockstoce .

The harpoon was an explode lance , a popular choice in New Bedford when it was the whale capital of the human beings back in the late 1800s . The patented gimmick enabled Bockstoce and colleagues to narrow down its deployment to sometime between 1885 and 1895 , putting the hulk at around 115 years older .
It was an unusual contribution to the growing body of evidence that bowhead whale , as well as being amongthe large whale , exhibit exceptional longevity , perhaps extend to over200 years – make it thelongest - living mammalon the planet .
How do you age a whale?
When you ’re brusque on 1900s - earned run average exploding lance , another way to age a whale is to look into their eye . Here , you find oneself theeye lensthat contains aspartate , which can come in left- and right - handed variants . How that aspartate changes over clip can reveal the age of an creature , as Dr Ariel Zeleznikow - Johnston explained inThe Future Loves You : How And Why We Should Abolish Death .
“ A babe bowhead hulk starts with 100 percent unexpended - handed aspartate in their eyes , but over time this will tend to an equilibrium of 50:50 leave : right molecules . In a process similar to radiocarbon dating , examining the exact ration of left- to flop - handed aspartate present in the lens can identify the age of an animal . ”
As Zeleznikow - Johnston make a guinea pig for in the volume , sometimes long lifespan can come at a cost , and for the bowhead whale , that includestiny testicles . The genetic quirk gives the giant ' cellular telephone clip to heal before they duplicate , but it may have a negative wallop on fertility .
