Secret Lives of Sharks
I was reading the news when this about the secret lives of sharks was revealed. A university research crew captured a whopping 12-foot Greenland shark from 6,000 feet below the surface of the Gulf of Mexico, unusually warm waters for the cold-water shark, and a first for such a catch from such depths. They weren't expecting to find a big black shark with a long dorsal fin in the warm waters of the Gulf of Mexico. It was the first deep-swimming Greenland shark to be captured there. These sharks are cold-water swimmers, and usually live in the northern Atlantic, near the Arctic Circle. When they swim south, as they often do, they swim deeper, at depths below 3,000 feet where the water is a bracing 40 degrees Fahrenheit. It's quite a contrast to the Gulf of Mexico's waters, more than 80 degrees Fahrenheit the day the shark was caught.
Mary Lee, a two ton great white shark, has been tracked off 9^th Street in Fernandina Beach, Florida, on more than one occasion, and if her regular vacation plans were known to the average swimmers (including me) human vacation plans might have been reconsidered, at least the swimming part.

Although no human body parts were found inside the Greenland shark and I am ever hopeful that none have passed through Mary Lee's digestive system, I have heard about several shark bite incidents recently in the news. I also read about a fisherman catching a shoe with a foot still inside it, a pretty grizzly catch to be sure that leaves one to wonder about the rest of the fellow. And then there's Shark Week and that movie that's been all the rage, Sharknado. Maybe I'll just never know all there is to know about the secret lives of sharks, and maybe it's better that way.
