There is a patch of ocean water east of Hawaii about 1,200 nautical miles where researchers had thought to be like some sort of desert. But for some other reasons unknown to the researcher every winter great white sharks would feed and leave the food in the abundant water along the Us and Mexican west coast.
Scientists at Stanford University and the Monterey Bay Aquarium in California hoping to unfold the secret lives of these great white shark led an expedition, White Shark Café. After, a month long journey in the moths of April and may they across this areas which are roughly said to be the size of Colorado which is actual teemed with tiny light sensitive creatures so tantalizing that the sharks cross the sea en masse to reach them this is according to the reports of San Francisco Chronicle.
This waters are also reach in squid, bigeye tuna, blue and mako sharks and other type of fish. A Stanford marine scientist Barbara Block had discovered the sharks’ hidden hangout and the largest congregation of white sharks was 14 years ago after she started attaching tags on animals.
Data was collected for years and this tracking tags would show the movement of this sharks to a specific area on an annual basis in month of December and this places imagery satellite suggested was barren. This tracking tags helped in the expedition to locate the sharks and track their movements, also as they were tracking the movement of the sharks they noticed even the diving behavior had changed and wasn’t entirely understood yet.
During their stay in the pacific the shark would show surprisingly behavior, the shark would vertical dive down to 1,400 feet to mid water where there is complete darkness and is populated by bioluminescent fish an then ascend to shallower waters of about 650 feet below the surface every night.
It’s the largest migration of animals on earth a vertical migration that’s timed with the light cycle and this is according to Salvador Jorgensen an expedition leader and Monterey Bay Aquarium scientist. During the day they g just below and come up during the night to more productive water under the cover of darkness.
