List members , you may recollect that Bowhead whales which inhabit the Arctic Ocean around Greenland are also supposed to have a lifespan stretching over hundreds of years...so , in the case of the Greenland shark , yet again we see evidence of long life spans for creatures living in the Polar regions , especially the marine creatures .
I sometimes wonder if these species of long living whales and sharks living in the Polar Oceans actually swim into the Hollow Earth (and back) during their annual migrations ?!
