This is a Greenland shark, one of the longest living vertebrates ever discovered. Scientists estimate some individuals can live for nearly 500 years because they grow extremely slowly in the freezing Arctic waters. These sharks move calmly through deep oceans and may have been alive during the time of the early colonization of North America. Want more interesting content like this ?
