Sharks decline by 97 percent in Mediterranean
The report by the Lenfest Ocean Program, which is based in Washington, used records like fishermen's logs, museum specimens and sightings to estimate the number and size of Mediterranean sharks over the past two centuries.
There was only enough data on 5 of the 20 big shark species present in the Mediterranean to be useful to the study: the hammerhead, thresher, blue and two species of mackerel shark, which averaged a decline of 97 percent.
"It will have a major impact on the ecosystem because large predatory sharks are at the top of the food chain," said Francesco Ferretti, the lead author of the report. Losing the top of the food chain can mean smaller fish thrive and consume more of their prey, upsetting the ecological balance.
"If we lose these sharks, we are going to lose this important portion of the ecosystem functioning," Ferretti said.

Heiky, I like this story. About 100 million shark are killed each year - many for their fins for shark-fin soup.

A magical moment in Red Sea, diving a school of hammerheads (Daedalus reef, egypt, June 2004)

There's no denying that sharks have an image problem. The serial-killer stare, the obscene grimace of warped teeth, the bloody feeding frenzies—it's no wonder they've been difficult to love as long as we've known them. And writers haven't always helped their cause.
Sharks are in decline worldwide !! whe have to do something to help them !they are animals to!

I feel with media stories of shark attacks and movies like Open Water and Jaws, etc., the general perception of sharks is negative. That said, any awareness of the positives is half the solution. That said, nice work.
The photo I took of a shark listed in the blog (http://www.flickr.com/photos/veritas1911/2568789925/) was my first real up close experience. I must say that I was in awe with their sleek beauty and ominous presence.

There are some initiatives aiming at protecting sharks and the wildlife overall. They need funds.

This 12 foot Hammerhead shark came within a foot of our boat as I was reeling in a tarpon a mile off of Key West. Shocking that such a large shark was that close and in such shallow water.

This small shark was caught and released on the Padre Island National Seashore. Removing the hook is more fun than catching the shark. Long pliers are a must.

This is a great white shark I snapped having a go at a seal decoy off the coast of Hermanus, South Africa. The point of the trip was shark cage diving under the guidance of Brian MacFarland (featured on Discovery Channel). I never went into the cage, being that I'm a complete pansy, but I got plenty of great snapshots of the beautiul great whites in action.

Sharks are my biggest fear. My family set up a shark feeding tour while visiting Tahiti...one of the scariest days of my life, but worth the pictures.

i only took this picture in one of new zealands biggest auqariums. i had to go there cause i actually broke my camera during my first diving trip in the ozean, where i "met" a shark ...
it was just amzazing to see these beautifull and scaring animals so close as a diver ... i look forward to do it again ^^
it doesnt metter how many humans they have (and will) kill, they dont deserve any of such silly treatments like we humans do to them ...
i think we killed more of our one race than they can do in millions of years !!! :

97% is a very large number -- it will be interesting to see how the ecosystem adapts to the void.

The Monterey Bay Aquarium was cleebrating the addition of their new shark exhibition. it was fantastic! I've never seen anything so cool. It's sad that people fear these animals.

The hammerhead shark photographs I have posted accompany those published with an article about The Galapagos Islands, featured in the June edition of Diver magazine (UK). The Galapagos is one of the earth's most fragile ecosystems, and the whole area is a marine reserve. Despite this, shark fin trawlers still frequent these waters, and decimate the shark populations there. If we can't protect an endangered species within a marine reserve, what hope is there?

If the shark population is declining world wide you wouldn't have been able to tell on this particular day.
I went on a "Shark Watching" adventure four miles of the North Shore of Oahu, Hawaii. No sooner had the crew dropped anchor, the 21' boat we were in was literally surrounded by sharks. The particular species we encountered that day was the Galapogas shark. By my best estimation there were at least 12 individuals circling the boat all between 6-10 feet long. These sharks were obviously conditioned to come running for dinner when they sensed the boat was near. Thank goodness people are not on the Galapagos menu, if we were, there would be a lot less of us swimming and surfing in Hawaii.

this image was taken 300 miles off the coast of Costa Rica at the island of Cocos. The water around Cocos is very nutrient rich which brings in a lot of sharks. sadly though the long line fishermen know this and target this area. speaking to the guides on our dive boat about this , they inform me that this long lining practice has had a dramatic effect on the numbers of sharks around the island.
