White Shark Café is an unofficial name given to an area halfway between Baja California and Hawaii in 2002 by researchers at Monterey Bay Aquarium Research Institute.
Before then, the area had not been suspected as a shark habitat. Using satellite tracking data however, they discovered that great white sharks frequently travel and loiter in the area.
It's unknown why they go there. There's little food for them there. Researchers equate the area to a desert.
At first they thought it was for mating purposes, but they've also tracked juvenile sharks to there, so they don't think it's just for that. They say that it takes sharks 100 days to get there, and when they do, they often dive to depths of 1,000 feet as often as once every 10 minutes.
