Stanford Study: Great White Sharks More Endangered Than Tigers

Posted by at 9:00AM

Great-White-Shark.jpgOne of the ocean’s most fearsome predators may be in dire straits. According to a research team led by Barbara Block, Professor in Marine Sciences at Stanford’s Hopkins Marine Station, there are fewer than 3,500 great white sharks remaining in the wild, making them rarer than tigers.

Scientists had previously believed great whites were rare but not endangered because they were spotted in a variety of distant locations. However, according to the team’s unpublished study, people have been seeing the same sharks.

To gather data, Professor Block and her team used satellite and acoustic tracking devices to monitor over 150 great whites in southern California and Hawaii. They found that great whites are remarkable long distance swimmers, capable of travelling 12,000 miles in nine months. In addition, the researchers discovered that sharks spotted in Hawaii were the same individuals observed off the coast of California just six months later.

Professor Block is a recipient of the Presidential Young Investigator Award from the National Science Foundation and the MacArthur Foundation Fellowship.

    Governments can easily take on the path to save the endangered animals. An encroachment can be easily setup covering a few miles and an aquarium sort of construction to breed and develop the animal life can be done. But, being lazy comes into the bloodstream as soon as one turns politicians, I suppose.

    We often tend to think about the fuel price rise but just like govt is not caring to increase the solar power production, we too tend to forget that we can think of more energy sources than the near diminishing fossil fuels.

    WHEN I WAS EIGHTEEN, BOTH MY DAD AND I WENT SPEAR FISHING OF OFF MOKULEAI, ON THE NORTH SHORE OF OAHU IN THE SUMMER. VISIBILITY WAS VERYGOOD ABOUT 100 FEET PLUS. WE ARE ACCUSTOM TO TIGERS AND OCCASIONALLY WOULD BE CIRCLED BUT NEVER ATTACKED. ONE INCIDENT IN 1973 AS WE WERE ABOUT DONE, MY DAD “SLOWLY” CAM TO MY SIDE AND TAPPED MY SHOULDERS AND SIGNALEDC TO SURFACE. HE WAS STILL LOOKING IN THE DIRECTIONS WHEN THEN GOT MY ATTENTION. IT WAS A GREAT WHITE FOR SURE. WE KNOW TIGERS, AND THIS BABY’S SIZE AND its UNIQUES CONTRAST REGARDING IT’S COLORS WAS NOT IT. MY THEN SQUEEZED MY ARM, LOOKED IN MY EYETS AND SHOOK HIS HEAD MOVING IT BACK AND FORTH EXPRESSING “NO”, WHICH I IMMEDIATELY KNEW WHAT HE WAS SAYING. WE THEN REACHED OUR BOAT AND GOT INTO IT. MY ADRENALINE WAS REALLY GOING. THIS THING THEN CAME UP ON OUR STARBOARD SIDE ENGULFING THE ENTIRE LENGTH OF OUR WHALER. IT WAS TWENTY ONE FOOTER, SO I GUESS IT WAS OVER TWENTY FIVE FEET. IT TOOK ME BY SURPRIZE THAT THEY CAME INTO HAWAIIAN WATERS. MY DAD THEN SHARED WITH ME THAT THEY WERE A COMMON SIGHT ON THE NORTH END OF KOHALA ON THE BIG ISLAND WHEN HE WENT DIVING WITH GRANDPA. HE WAS GLAD TO SEE ONE THAT DAY. IT WAS ALMOST TWENTY YEARS SINCE HE FIRST SAW ONE SINCE.

    It would be a real tragedy if one of the greatest and most awesome fish in the sea was to go extinct in today’s ttime of technology and knowhow. We need to start doing more to protect this neccessary species or nature’s balance will be severely affected included humans. Just because these are not cute and cuddly animals doesn’t mean they don’t serve a purpose. The are nature’s clean up crew. WE are in THEIR world and until we realize that we need to understand that reguardless of what the reason when you enter the water you play by THEIR rules. If they wanted us make no mistake about it their acute senses realize we are there as soon as we enter the water and they could have us for lunch at anytime. They don’t want us they want to do what they do and that is to be left alone and do what nature entended them to do. We do the harm to them not the other way around and if we don’t change our attitude towards this beautiful creature then our entire ecosystem is going to suffer. Please reach out and donate whatever time or money in preserving natures most awesome predator befor its to late.

    Please find a way to save the sharks. I love sharks because they are very unique creatures. Im interested in marine animals only being 12. Capture some sharks, take them to a shark saving society, and breed them.Then set them free when your sure they wont become endangered.
