18-foot fish may help crack migration mysteries, team says.
ON TV: Shark Men—Biggest and Baddest premieres at 10 p.m. ET/PT on Sunday, May 8, on the National Geographic Channel.
Talk about a big fish—an expedition crew has hauled up—and released—what the team says is the biggest great white shark yet caught.
The 17.9-foot-long (5.5-meter-long) male behemoth was found off Mexico's Guadalupe Island (map) in fall 2009.
The animal breaks the team's previous record of 16.8 feet (5.1 meters), set when they caught a female great white named Kimel. (Both records are unofficial and not maintained by a formal organization.)
The new titleholder was named Apache after the dog of Brett McBride, boat captain on the National Geographic Channel show Shark Men. (The National Geographic Channel is part-owned by the National Geographic Society, which owns National Geographic News.)
Shark Men chronicles the work of scientists and fishers who catch and release great whites in an effort to figure out where the mysterious giants breed and give birth. The scientific team is led by Michael Domeier, president and executive director of the Marine Conservation Science Institute.
The two-ton Apache put up a fight—at one point breaking free from his barbless hook, said expedition leader Chris Fischer.
"The battle with Apache was like nothing we've ever dealt with," Fischer said.
Once on board, the researchers fitted the fish with a satellite-tracking tag, took a blood sample, and released him, watching him vigorously swim away.

"He was all scarred up and had big marks all over him—you could tell he was just a bad-ass shark," Fischer said.
"It was so impressive and so humbling to be near him."
Size Doesn't Matter for Shark Research
In large ocean fish species, females are almost always bigger than males, because they need more girth to carry their young, Fischer noted. (See great white shark pictures.)
However, even a male of Apache's size is not unheard of among great whites, other experts say.
"That is one big shark, [but] I have no doubt that this isn't the largest white shark in the wild," John O'Sullivan, head of the Monterey Bay Aquarium's White Shark Program, said by email.
Shark expert Kenneth J. Goldman added, "I don't see anything overtly magnificent about it being so large. It's just another adult male they've tagged."
That's because size alone doesn't tell scientists much, said Goldman, a fishery research biologist at the Alaska Department of Fish & Game in Homer.
Instead, Apache's real value would be in helping to resolve the lingering mysteries of great white behavior.
Biggest Shark May Help Crack Mysteries
Expedition leader Fischer agrees—and he and his team are now watching to see where Apache goes.
For instance, recent research suggests that Pacific great whites gather in specific spots near the coasts—including the Guadalupe Island site—and then travel to a "cafe" in the middle of the ocean to feed. The animals often return to the same aggregation sites after feeding.
But this is still a tentative theory, so it "would be groundbreaking if, [say], Apache left Guadalupe and went to the middle of the ocean and [returned] to a different aggregation site," Fischer said.

Overall, tagging sharks to figure out where they migrate and congregate may help conservationists protect the species, Fischer added. Great whites are considered vulnerable by the International Union for Conservation of Nature.
Meanwhile, Apache lives on, he said, as a "giant male shark out there doing his great white thing."
“We were coming back from the isle of Tinian to Leyte. We delivered the bomb. The Hiroshima bomb.......”
Behemoth.
He actually looks pissed off!
They’re gonna need a bigger boat.
“Here fishy fishy”.....
OK, size matters, size doesn't matter. I wish somebody would get it right.
That’s one big fish! I saw on Drudge that there is a 20’ off of Martha’s Vineyard beach. Just like the movie Jaws right? Here is the link,

It’s probably becuase he is. Go ahead and love that thing, give em a big ‘ol hug and see what happens.
Yo media, JUMP THIS!!!

apples and bananas!
One of the all-time great movie soliloquies.
“Lets throw him back. You get the head, I’ll get the tail”
Since they have GPS tracking data it would be cool to see a website with each sharks location in real time. Kind of like those airline tracking websites. You could click on each dot and pull up the personal info recorded on each shark at tagging and see its migration routes since the tagging.
It would be cool to see where they all group at different times of year. They could have different color codes for the different types of sharks.
So, how’d they get it back overboard?
Crikey! That’s a lot of shark.
That shark looks seriously pissed off.
Imagine if you could see the names and occupations of the people they ate.
the guy with the hose is wearing gloves!! thank god cause thats gonna help.
