Shark Attack interview

One of the Shark Week shows the other night had an  interesting hypothesis about why so many sharks in Southern California. The seal population at Guadalupe Island has exploded, and sharks from all over the Pacific are now heading there. The shark pecking order is by size, and the smaller sharks are basically being kicked out, and then heading north east, to the SoCal coast. 

They need a few more years of tracking data before they can confirm the hypothesis.

The video of the shark behavior to determine alpha is pretty cool. They do a parallel swim, and then the larger shark looks at the smaller, nods its head a few times and opens its mouth a bit, almost like it's talking. The smaller shark almost always boogies.
