Mysterious great white shark lair discovered in Pacific Ocean

The sharks’ annual pilgrimage to the mid-Pacific region from the coasts of California and Mexico has baffled scientists for years, not just because it is so far away — it takes a month for the sharks to get there — but because it seemed, on the surface, to be lacking the kind of prey or habitat that the toothy carnivores prefer.

But the researchers made a remarkable discovery. Instead of blank, barren sea, the expedition, led by scientists with Stanford University and the Monterey Bay Aquarium, found a vast community of tiny light-sensitive creatures so tantalizing that the sharks cross the sea en masse to reach them.

The primary lure, scientists believe, is an extraordinary abundance of squid and small fish that migrate up and down in a little understood deep-water portion of ocean known as the “mid-water,” a region skirting the edge of complete darkness that could provide an immeasurably valuable trove of information about the ocean ecosystem and climate change.

“The story of the white shark tells you that this area is vitally important in ways we never knew about,” said Salvador Jorgensen, a research scientist for the Monterey Bay Aquarium and one of the expedition’s leaders. “They are telling us this incredible story about the mid-water, and there is this whole secret life that we need to know about.”
