Authorities in Hawaii have stopped searching for a 35-year-old Sunnyvale man who was last seen Tuesday afternoon surfing off a beach on the north shore of Oahu. The Honolulu Advertiser is reporting the man is from Beijing and has been living in Sunnyvale. Authorities in Honolulu have not identified the missing surfer. During the three-day search, there were two unconfirmed sightings of his body and the discovery of the surfer's black shorts, which were shredded, according to fire officials. Tuesday evening, rescuers reported seeing what appeared to be a body in an area where waves break, according to the fire department. Wednesday rescue crews spotted a body in the ocean surrounded by three large tiger sharks, about a quarter-mile from shore, according to the Honolulu Fire Department. The sharks, estimated to be between 12 to 15 feet in length, were behaving aggressively in close proximity to the body, which disappeared shortly after it was seen, according to the Honolulu Fire Department. The sharks' presence prevented divers from entering the water to retrieve the body, according to fire department officials. The shark sightings also resulted in the closing of beaches in the area. After calling off the search Wednesday, rescuers renewed their efforts Thursday morning after the surfer's shredded black shorts were found on Papailoa Point beach. Honolulu police confirmed the shorts belonged to the missing surfer. The multi-agency search covered about five square miles.. The missing surfer's family is being assisted by the Visitor Aloha Society of Hawaii, according to officials. The agency told the Honolulu Advertiser that it is helping the man's wife of six years and his family.

The great white shark seems to be a fan of the Florida winter. Electronic tracking tags placed on three sharks off Cape Cod last summer have surfaced near Jacksonville. The first tag began transmitting data in mid-January about 50 miles off the city. The second popped off in early February and the third surfaced Monday. Energy and Environmental Affairs Secretary Ian Bowles said data analysis from the first two sharks showed deep dives to 1,500 feet and migratory travels along the eastern seaboard. Data from the third tag is being analyzed and two other tags haven’t surfaced. The tags, placed on the whale by harpoon, were the first successful tagging of great whites in the Atlantic using satellite -based technology.

Here's my own personal shark story.
No body was harmed in this story, but my friends and I were a surprised to learn about it.

1992 I was visiting a friend on the island of Kawaii for St. Patricks day.
I didn't plan for the holiday, just that their condo time share happened to coincide with it.
While we were there, some of us decided to head up to the north shore, near the Napali coast. They filmed the first Jurassic Park movie there.
We headed to the Barking Sands beach and were surprised to find the beach practically devoid of any other beach goers.
Oh well, that just means no crowds, kids, or unwanted noise.
We swim, relax, and head back home. While at the condo, one of my friends happens to be reading USA TODAY, and on the page that gives little quips of news around the country there was a piece about Hawaii, the islan of Kawaii to be exact, and it involved a shark attack THE DAY BEFORE.
Fortunately for us, we didn't venture out past the breakers that line the shore about 50 yards from shore. That's where the attack took place.
