This Is What Life Is Like From a Shark’s Perspective

Cameras and other equipment attached to multiple species of sharks provide a rare look into a world you'd otherwise avoid

Odds are you’ll never see the ocean from the point of view of a school of sharks — unless you’re willing to make that the last thing you’ll ever see. That’s why we should be grateful for oceanographers at the University of Hawaii and the University of Tokyo. As they are reporting today at an oceanography conference in Hawaii — co-sponsored by the Association for the Sciences of Limnology and Oceanography, the Oceanography Society, and the American Geophysical Union — they have been attaching cameras and sensors to various species of captured sharks and releasing them back into the ocean to do, you know, shark stuff.

Some of what the researchers are discovering is overturning previous theories of shark behavior. Lazy critters — except when they’re looking for dinner — sharks were always assumed to move with as little tail power as possible and instead rely on gliding. But onboard accelerometers now show that they make more of an effort than that, preferring powered swimming to a simple drift. The deeper the sharks go, the slower they move; and when they’re near the ocean bottom, they often simply swim about in aimless circles. Tiny brains do not, evidently, lend themselves to busy days.

But the most striking part of the new studies is simply the shark’s eye view of the world — which is equal parts scary and thrilling. Little fish get out of their way fast, which is wise. The sharks themselves appear quite content to travel about in schools made up of multiple shark species, neither especially loyal to their own kind nor especially fearful of any others. But again, they’re sharks. They may not have much to do, but they don’t have much to be afraid of either — except, of course, of humans, who, through fishing, kill an astounding 100 million sharks per year.

This one seems to have developed a "lean",

When "SLICED" how do the eyes compare to a bird's under the microscope: for analytical vision of a food source?

NOT MADE BY NATURE! Just because something exists in nature doesn't mean it was invented or made by Nature. If all the chemicals necessary to make a cell were left to themselves, "Mother Nature" would have no ability to organize them into a cell. It requires an already existing cell to bring about another cell. The cell exists and reproduces in nature but Nature didn't invent or design it! Nature didn't originate the cell or any form of life. An intelligent power outside of nature had to be responsible.

Natural laws can explain how an airplane or living cell works, but it's irrational to believe that mere undirected natural laws can bring about the origin of an airplane or a cell. Once you have a complete and living cell then the genetic program and biological machinery exist to direct the formation of more cells, but how could the cell have originated naturally when no directing code and mechanisms existed in nature? All of the founders of modern science believed in God. Read my Internet article: HOW FORENSIC SCIENCE REFUTES ATHEISM

Only evolution within "kinds" is genetically possible (i.e. varieties of dogs, cats, etc.), but not evolution across "kinds" (i.e. from sea sponge to human). How did species survive if their vital tissues, organs, reproductive systems were still evolving? Survival of the fittest would actually have prevented evolution across kinds! Read my Internet article: WAR AMONG EVOLUTIONISTS! (2nd Edition). I discuss: Punctuated Equilibria, "Junk DNA," genetics, mutations, natural selection, fossils, genetic and biological similarities between species.

Natural selection doesn't produce biological traits or variations. It can only "select" from biological variations that are possible and which have survival value. The real issue is what biological variations are possible, not natural selection. Only limited evolution, variations of already existing genes and traits are possible. Nature is mindless and has no ability to design and program entirely new genes for entirely new traits.

What about genetic and biological similarities between species? Genetic information, like other forms of information, cannot happen by chance, so it is more logical to believe that genetic and biological similarities between all forms of life are due to a common Designer who designed similar functions for similar purposes. It doesn't mean all forms of life are biologically related! Also, "Junk DNA" isn't junk. These "non-coding" segments of DNA have recently been found to be vital in regulating gene expression (i.e. when, where, and how genes are expressed).

@BabuG.Ranganathan  That's not completely true.  Species can be formed by aberrations of energy.  One cell can be attracted, or fused, with another cell, by molecular actions of ions in a certain set of conditions.  Granted, the probabilities are astronomical, but over time, they certainly can, and do happen.  Just the same as we can make them happen in a lab environment.


* I've been recognized and written about in WHo's Who in America since 1987.  So what.

@BabuG.Ranganathan  I don't know where the hell you got your "B.A. theology/biology", Babu, but in the civilized world there is no such degree. No legitimate university issues any kind of a religion/science degree. No legitimate educational institution would mix religion and science in a class, let alone an entire curriculum. Go sell your mumbo jumbo to your own people.
