Longest childhood ever...

From an article in the New York Times about the warming, changing oceans:

The world’s longest-living vertebrate is not the friendly giant tortoise, the breathtaking blue whale or the saltwater crocodile, which can terrorize the imagination of toddlers and centenarians alike. It’s the shuddersome, floppy Greenland shark, which can live to 300, perhaps even longer, its life span slowed and distended by the deep cold of the northern oceans. Greenland sharks do not even reach sexual maturity until about age 150, which means that today there are, swimming slowly through the waters of the far North Atlantic, the equivalent of preteenagers born not long after the 19th-century heyday of New England whaling, as the Industrial Revolution was just metastasizing beyond the Anglosphere. Since then, measured by weight, 90 percent of the largest creatures sharing the oceans with them have disappeared.
