Great white shark amazes scientists with 4,000-foot dive into abyss

By: Pete Thomas, GrindTV.com

A great white shark known to frequent New Zealand waters has given new meaning to the term "Down Under."

Scientists revealed that the 15-foot shark they've named "Shack" probed to 1,200 meters, or 3,937 feet, as it traveled across open ocean.

Malcolm Francis, principal scientist in charge of the tagging study, is calling this "the world's deepest great white shark dive record" and said it extends the predators' known vertical range by about 600 feet--which is substantial given that great whites, until fairly recently, were regarded as coastal predators.

If placed into perspective Shack might as well have been swimming upward into outer space: That's how bizarre the marine universe is at the depth to which the shark delved.

It passed through the Mesopelagic Zone (600-3,300 feet), also referred to as the "Twilight Zone," and continued well into the Bathypelagic Zone (3,300-13,000 feet), or the "Midnight Zone."

This is the realm of alien-like sea jellies and squids. It's also home to monster-like, needle-toothed predatory fishes and eels that utilize bioluminescence for light and have spawned nature TV specials and, subsequently, nightmares.

What was Shack doing in the company of viperfish, hatchetfish, dragonfish, sabertooth fish, fangtooth fish and gulper eels?

Unfortunately, nobody knows with certainty. Scientists at New Zealand's National Institute of Water & Atmospheric Research did not address this in a five-year study that also tracked the country's white sharks migrating to warmer areas during the winter.

However, a Southern California-based researcher, who has tracked great whites to about 3,000 feet, believes they're searching for food at deep-water haunts. The chief food source would be various squid species, including the fabled giant squid, whose epic battles with sperm whales are legendary.

Michael Domeier, who runs the Marine Science Conservation Institute in Fallbrook, has offered this theory based largely on anecdotal evidence.

His study has tracked white sharks from Guadalupe Island off Mexico to a vast, mid-Pacific area between Baja California and Hawaii. A similar tagging effort at the Farallon Islands west of San Francisco has followed white sharks to the same spring-and-early-summer habitat.

In this area there is little productivity. However, scientists have seen squid there, and they've encountered sperm whales, which might imply a squid-based ecosystem far below the surface. Domeier's crew also found a giant squid carcass that had been chewed on.

Though other scientists do not qualify this as proof, the theory is not far-fetched (there are giant squid off New Zealand, too). And as for possible encounters between great whites and giant squid, that's a TV special the "Shark Week" producers at the Discovery Channel ought to be working on without delay.

Two years later, alien-like sea creature gains Internet stardom

Rare creatures are deceivingly swift

Among the more bizarre-looking visitors to California waters this summer are Mola molas, or ocean sunfish, which are being seen in unusually high numbers. But it's a stunning photograph of one of these gentle giants that appears to be getting the most attention. The image, captured off San Diego by Daniel Botelho, became an instant hit after being posted last week on his Facebook page.

There has been some research done lately as well stating that the sharks are making practice attacks on seals and sea lions not eating them just attacking them and leaving them. As well as some studies are showing that the sharks are beginning to work in groups or packs to survive. Plus the sharks can work as a group to take down a sperm whale and that is plenty of blubber and nutriants to survive on for quite some time. As far as the squid go the great whites are also oppertunistic predators and if a squid was to come by they prob. would not hesitate to take a bite and unlike a sperm whale the whites are designed with a lot better teeth and more hydrodynamic design for better speed and manouverability as well as a blood system that keeps them warm which would help out in those deep cold areas. So with all the evidence provided above the oldest and best predator to ever live has just learned some new tricks to put in the old playbook.

@ beaver02: are you kidding me? - even orcas (which, I might add, are known to kill and *eat* great whites) won't attack spermwhales, and they're far more effective pack predators than sharks will ever be. (keep in mind that sharks don't have an effective means of communication, while orcas use their 'sonar language' to coordinate attacks and improvise whenever something unexpected happens - which is one of the reasons why instances of packs of orcas killing whales are common and well-documented, while instances of packs of sharks hunting whales are practically unheard of).

As for your remark about the teeth; FYI, spermwhales (along with most other squid-eating cetaceans) swallow squid whole. They don't even *use* their teeth when eating squid, simply because sucking them in and swallowing them right away is much more effective than biting them to pieces.

As for the possebility of great whites hunting squid in deep water; considering that squid and cuttlefish are among the favourite prey of reef sharks and IIRC bullsharks, I really wouldn't be suprised.

A couple of thoughts. I am particularly intrigued by the giant squid hypothesis, i.e., because nobody has observed White sharks mating, not to mention the ostensible severity, I have never fully endorsed the idea the scars commonly seen on large sharks are "mating" scars. Perhaps the marks of giant squid? Or a giant red herring, can't tell which. As for White sharks "group hunting" - I think White sharks have learned that when a prey item tries to evade another attacking White shark, it is effective to swim in almost concurrently to realize an opportunity. But this is hardly "group hunting" in any mammalian sense. Recall, most "group hunting" involves closely related groups of lions, chimps or orca, et al. Being highly migratory, I would imagine unrelated sharks are just being opportunistic, but very aware nonetheless. I notived this behavior on a cage dive, i.e., two White sharks converged on a noise I created on the cage. But these sharks hunting as a team? Uh, no. Last thing. People. The notion that White sharks need some high caloric intake (seal) to "justify" the energy expediture of an attack is a myth. White sharks are generalist feeders that will eat very small fish or marine life. Humans are made of protein, not cardboard. A full human leg is enough to get to the next meal, believe that.

Would a squid even have enough caloric value for a Great White? Humans are generally spit-out by Great Whites, for their lack'off "nutritional" value relative to fatty seals, tuna, and whale blubber.

If giant squids can feed a Sperm Whale, which is considerably larger than a Great White, why couldn't it possibly feed the shark?
As long as the shark eats many squid to keep its needed diet, it's completely possible. Great Whites usually favor seals because of their fat. However, they also dine on 6-7 foot tuna and such. So a giant squid would be a good meal for a shark.

"I thought It was not proper written if starting a sentence with "and"." No offense buddy, but you have no room critiquing their grammar. Your sentence structure is for worse than their attempt at starting a sentence with "And". And for future reference, it is becoming more acceptable in the written English language to use a conjunction at the beginning of a sentence when done so properly. Google it and you'll learn more about it. In the mean time, worry about correcting your own sentence structure before worrying about this single conjunction confusion.

It was a stylistic rule back in the 40s or 50s or so to never begin a sentence with "and" or "but," but this rule has been largely abandoned today. There was simply no grammatical reason for it. Beginning with "and" or "but" doesn't change the logical meaning of the sentence (as "true" errors like double-negatives do), and serves nicely to conjunctively or disjunctively link the sentence's idea to the previous. Using the old rule you could use the exact same words and just replace the period with a semicolon, but this was unnecessary and just made the sentence seem tediously long.

Pete Thomas' article is filled with spelling and grammar errors, but I am quite sure he could not care less. Thomas wrote the article to inform people about the idiosyncratic great white shark, not to flaunt impeccable grammar, spelling, rhetoric, or diction. Who cares whether 'and' is properly placed in an internet article about a shark? Ironically, your sentence is far more defective than any of those in the article. And the rest of you that are critiquing the article do need to find some better use of your time. Butterflyglenna, frankie caputo and kyle parks' comments are amusing though; and I agree with robert goodin.

Using their gelatinous "pits of lorenzini" sharks can sense electrical pulses such as those emitted by muscular activity. They also have chemotactic organs concentrated on the anterior part of their cephalic cavity and pits full of cilia homogeneous to that of our third semicircular internal ear canal all over their lateral line system. Considering all these sensory organs, I hardly think the shark even needs vision to navigate at great depths.

I think the great white was just curious. I's not like it has to worry too much about other predators.

A shark has a set of special olfactory receptors. It can smell the water in a sense. It's drawn to the deep by blood and it was just there to see if it snack on what ever it smelled. I think it would most likely be blind in the water that deep. But maybe not with its blood hound like abilities. i wonder if a shark has ever been caught with tentacle sucker-ring marks? Like on a sperm whale. then again a shark could just go deep enough to see all the deep sea critters light up. then just hunt the lights.

Has anyone considered the skin of a shark yet? is it not true that they are made of little barbs that act like sand paper when rubbed against? If you was a squid and you tried to grab something that was cutting your suckers open, would you bothered to hold on? If you consider the way a shark attacks you would also consider that the squid may have not the chance to defend itself before losing a chunk out of his body. Things people over look when trying to seem intelligent are very wonderful facts that are easily Googled.Oh and for the english professors on here......seriously is there a reason to be that rude about how people talk to rather type the way they talk? DO you honestly strive to speak with the most proper of english terminology? By the way...For the kid in high school, if you can not stand they way your 'friends' talk then why do you hang out with them? Seems a bit of a hypocritical state if being does it not?

Perhaps the depth the shark dove to has nothing to do with feeding. Could it be possible? Of course it's possible. How much of the Earth's waters have we explored? 1% maybe? How much do we really know about the habits of sea creatures? Practically nothing! That is why scientists tag and follow them. For all we know, a deep dive to great pressure is like a visit to the chiropractor. Who the *^@!$*^ knows. Certainly there is a reason why it goes there, right? Maybe there is no reason. Perhaps the shark decided to go deep with no reason. Just as any of you can turn left or right at the light tomorrow or go straight ahead just out of free will. All animals including us follow instinct. But, it is my belief, that almost all the higher forms of life have a degree of free will. Who knows, but one.
