A specimen of shark known as the "Greenland" shark has been found and it is estimated that it is around 512 years old, making it the oldest known living vertebrate. They grow at the rate of 1cm a year, and this one is 18 feet long. You do the math. They swim as deep as 1.2 miles where they have been spotted by deep sea mariners. I find this amazing, and it certainly puts the petty squabbles of Humankind into some sort of perspective. That is an awesome age. Some people living in the present think they are so important. Some obvious names spring to mind. They don't care about the wondrous abundance of nature on this planet. Sometimes I agree with the deep-Earth ecologists, who advocate abandoning technological society so as to preserve the natural World. What do you think?
