Amazing Footage from a “Techno Fish”!

A Harlequin Sweetlip juv. is doing this move to protect itself from predators, it looks like a big toxic ball! as the older it get as the less it needs to protect itself as the slower it can do it! Amazing creatures, so advanced!

With a mouthful of teeth, sharks do not seem to need much protection.
In fact one shark goes through thousands of teeth in a lifetime. Each row of succeeding teeth is larger than the set before.
But sharks´teeth are built for eating. The shape of a sharks teeth depend on the type of food it eats, and some sharks’teeth change shape as they grow older and their diet changes to suit the needs of their growing bodies.
sharks also have other types of protection. A protective lid, called the nictitating lid, helps keep its eyes safe from harm when it attacks prey or nears an unfamiliar object. Some sharks will also roll their eyes back into the sockets showing only the whites while attacking prey to protect the more important seeing part of the eye.
Bottom feeding sharks, such as the angel shark or wobbegong, have coloration matching their environment. Others will bury themselves in the sandy ocean bottom.
However, sharks have little or no protection from humans who hunt them for almost every part of their body to make leather, jewelry, soup, cosmetics, and other items. Sharks are also hunted for sport and many are inadvertently caught in fishing nets or in nets placed to protect humans.

Shark finning
However; the product that drives the market are the fins. After drying, collagen fibers are extracted from them, cleaned, and processed to make ’shark fin soup’. In spite of the fact that these fibers have little flavour or nutritional value, the soup is considered a delicacy, and may sell in the Orient for more than $100 ( £65) a bowl. As long as the humans pay a lot of money for these fins, it will never stop, and we will kill  the sharks and ourselves
The explosive growth of the Chinese economy and rapid expansion of trade with the outside world during the 1985 and 1995 created an unprecedented situation. Suddenly there was an insatiable demand for shark fins of almost any size or type. Improvements in shipbuilding and navigational electronics meant that shark fishing boats could now go anywhere in the world, moving from one place to another as local shark populations were destroyed. The fins are now so much more valuable than the rest of the shark that the carcass is often discarded after the fins are removed, to save storage space on the boat. Often the fins are sliced off when the shark is still alive and the mutilated shark is dumped back into the water, where sinks straight to the bottom because without back fin can´t swim, to die a slow and agonizing death.

Helping To Protect Sharks
Since sharks reproduce at a much slower rate and mature more slowly than bony fish, it is important that people are careful not to deplete the shark population to a point where it can not be recovered. In some cases the environments in which the sharks live are being destroyed.
While sharks have a bad reputation, they rarely attack people unless they are provoked or mistake a human for their normal prey. More people drown in the ocean each year than are attacked by sharks. Only a few of the 365 types of sharks, the bull, the great white, the oceanic white-tip, and the tiger shark are aggressive toward human.
Encouraging the use of electric barriers instead of nets to keep sharks out of an area is one way to help. Also discourage the hunting of sharks for sport or the production of unnecessary articles such as jewelry and souvenirs. In addition learn more about sharks and inform others of ways to live peaceably with these fascinating animals.

A Shark’s Sixth Sense
In order to live and hunt in the ocean waters, sharks have the same 5 senses as human do. They have smell, taste, touch, hearing, and sight. These senses vary in their strength. Many sharks have sharp eyesight, some of which seem particularly sensitive to movement. Most sharks also have a well developed sense of smell.
However, sharks possess a sixth sense which people do not have. Sharks are able to detect weak electrical signals generated by their prey. This sense is detected through small sensory pores called ampullae.

Shark Facts
• The smallest shark is the dwarf dog shark which is 6 ½ inches (16 cm) in length.
• The largest shark, ranging up to 40 ft. (12m) in length is the whale shark.
• Whale sharks are large non aggressive creatures which will sometimes allow divers to hitch a ride by holding on to a pectoral fin.
• Most sharks give birth to live young rather than lay eggs.
• The shark with the longest tail is the thresher shark. Its tail can be 5-8 ft. in length, or as long as its body.
• The hammerhead shark swings its head from side to side as it swims, allowing it to use its well developed sense of smell and many ampullae to search for prey in a wide variety of directions in a small amount of time.
• The fastest shark is the Mako, which can swim at 20 mph (32 kph) and leap completely clear of the ocean surface when it is excited.
• Angel sharks have extra large pectoral fins resembling angel wings. These sharks spend their lives mostly on the ocean bed resting in the sand waiting for prey to come to them.
• Some sharks migrate hundreds of miles using what scientists believe to be a sense of the earth’s magnetic field to guide them.
• One shark makes oval shape bites in its victim, by creating a suction with its lips and swiveling around for the bite. It is appropriately named the cookie cutter shark.
• One of the smallest sharks, the lantern shark, grows to only 8 in (20 cm) in length and glows in the dark.
• The most recent discovery of a shark was not made until 1976. This was the large Megamouth shark, of which only five more have ever been found. This unusual shark which feeds on krill has luminous organs around its mouth.

Things worth knowing about Sharks:
“He who fears an animal will only see its threatening behaviour” – this quote from Nobel Prize winner Bertrand Russell seems to capture better than most sentiments the relationship between shark and man. Most people simply know too little about sharks in order to overcome the fear being propagated through the media. Sharks are always depicted as monstrous man-eaters in sensational films and reports. A new image of the animals is only slowly emerging in the media. This “man-eater” is gradually being portrayed as an intelligent predator with more of an aversion to humans. Sharkproject has compiled facts and information on this here in the Shark Compendium.
They will constantly be developing this knowledge library further, adding new research findings and chapters. So it’s worth dropping by at regular intervals!

Haiothek Wissenswertes über Haie
“Wer Angst vor einem Tier hat, wird in dessen Verhalten immer nur das Bedrohliche sehen!” pointierter, als dieser Ausspruch des Nobelpreisträger Bertrand Russel, kann man das Verhältnis zwischen Hai und Mensch nicht beschreiben.
Die meisten Menschen wissen einfach zu wenig über Haie, um die über Medien permanent geschürte Angst zu verlieren. In sensationsgierigen Filmen und Berichten sind Haie immer noch die menschenfressenden Monster. Erst langsam setzt sich ein neues Medienbild der Tiere durch. Aus dem “Menschenfresser” wird so allmählich ein intelligenter und dem Menschen gegenüber eher scheuer Räuber.

VSO Day

Victory in the Southern Ocean Day for the Whales

Pilot Chris Aultman and crewmember Mark Cullivan in an emotional embrace.
Photo: Barbara VeigaIt’s official – the Japanese whaling fleet has called it quits in the Southern Ocean, at least for this season. And if they return next season, Sea Shepherd Conservation Society will be ready to resume their efforts to obstruct and disable illegal Japanese whaling operations.

“The Nisshin Maru made a significant course change immediately after the Japanese government made it official that the whaling fleet has been recalled,” said Captain Alex Cornelissen from the Bob Barker. “She looks like she’s going home!”

The Sea Shepherd ship Bob Barker has been tailing the Japanese Nisshin Maru factory ship since February 9th making it impossible for the whalers to continue their illegal whaling operations.

“I have a crew of 88 very happy people from 23 different nations including Japan and they are absolutely thrilled that the whalers are heading home and the Southern Ocean Whale Sanctuary is now indeed a real sanctuary,” said Captain Paul Watson.

The Sea Shepherd ships Steve Irwin, Bob Barker, and Gojira will remain in the Southern Ocean to escort the Japanese ships northward. “We will not leave the whale sanctuary until the last whaling ship has departed,” said Gojira captain Locky MacLean.

“This is a great victory for the whales,” said Captain Watson, “but we did not do this alone. Without the support of the people of Australia and New Zealand, we would not have been able to send voyages out for seven seasons from Australian and New Zealand ports. We are grateful to Senator Bob Brown and the Australian Greens Party. We are very grateful to Mr. Bob Barker for giving us the ship that turned the tide in our efforts to force the Japanese fleet from these waters. We are grateful to all our onshore staff and volunteers, supporting members and ship crews. We are grateful to the Chilean Navy and the government of France for their support. It is a very happy day for people everywhere who love whales and our oceans.”

It’s official – the killing of whales in the Southern Ocean Whale Sanctuary is over for this season and the whalers did not even take 10% of their quota. Sea Shepherd estimates that over 900 whales have been saved this year.

“It’s a great day for the whales,” said Sea Shepherd Chief Cook on the Steve Irwin Laura Dakin of Canberra, Australia, “and it’s a great day for humanity!”

Despite many press releases worldwide the Thai Government DOES NOT close all dive sites in the Andaman Sea and the Gulf of Thailand region!
Correct is that a few Dive Sites will be closed due to research. The dive sites which will be closed do not reflect on diving pleasure in Thailand. Please find the links where you can see and find more detailed information that only a few reefs will be closed for scientific research purposes:
Another fact: The coral bleaching comes from to warm water temperatures and not from Divers at all!

http://www.tatnews.org/VISITOR-INFORMATION/5263.asp

Also coral bleaching phenomena is not damaging more than 10% of all corals throughout the Kingdom’s seas, but partly in shallow water areas some of the coral life. You still can enjoy wonderful and colourful reefs in the Andamnan Sea and as well in the Gulf of Thailand!

We awaiting you and looking forward to some amazing dives!

Pressemeldungen mit mangelhafter oder gar gänzlich fehlender Recherche ziehen Kreise und verbreiten, alle Riffe in thailändischen Marine National Parks werden gesperrt - Das ist SCHWACHSINN..!!!Richtig ist, dass ein paar wenige Tauchpläzte zu wissenschaftlichen Studienzwecken gesperrt werden, die nicht tauchrelevant sind, bzw die sowieso kaum einer der thailändischen Tauch-Fan-Gemeinde kennt oder jemals betaucht hat. Namentlich und geografisch gelistet findet Ihr die gesperrten Riffe unter folgendem Link:

Dem ungetrübten Tauchspass in thailändischen Gewässern steht also nach wie vor nichts entgegen!

Wir erwarten Euch und wünschen euch immer gut Luft!

This is the deepest known cave in Thailand and all of it is underwater. It is a very deep vauclusian resurgence with two surface pools which join underwater. The sump contains fresh water, even at -240m. There are several other deep resurgences in this area and the source of the water is not known.
The site was first dived by Matt London and the Thailand Cave Diving Project around 1993. The two surface pools were connected at a depth of 84m. These dives pushed the cave to a depth of -120m using open-circuit equipment. Exploration was resumed in December 2005 when Bruce Konefe, Cedric Verdier and Mike Gadd reached a depth of -150m using rebreathers. In May 2006 Verdier and Gadd extended the cave to -201m. The bottom of the sump was eventually reached by Ben Reymenants in November 2006 at a depth of -240m.
If you do this please ask us first. It is dangerous to dive in caves especially if you go deep! Instructors and divers lost there life in these cave.
But nevertheless there are also many Caves around to reach by foot on land. You’ll need torches to explore these caves and if you like Bats then this is a must!
All can be reached by walking from this lake!
If you have any questions please contact me!
Have lots of fun exploring undiscovered worlds!

A third of all animals and plants on earth face extinction — endangered blue whales, coral reefs, and a vast array of other species. The wave of human-driven extinction has reached a rate not seen since the fall of the dinosaurs 65 million years ago.

But there is a plan to save them — a global agreement to create, fund and enforce protected areas covering 20% of our seas and lands by 2020. Right now, 193 governments are meeting in Japan to address this crisis. But without public pressure, they are likely to fall short of the bold action needed to avert the collapse of ecosystems the world over.

This summit ends this week — we have no time to lose. Let’s rapidly build a global public outcry urging governments to save all life on earth from runaway decline. Sign the petition below and it will be delivered directly to the meeting:

To all parties of the Convention on Biodiversity:
One third of Earth’s species face extinction. We call on you to urgently agree to create, execute and fund the protection of 20% of our oceans and lands by 2020. Only bold and immediate action will protect our planet’s rich diversity of life.

Sea Shepherd Unveils Interceptor Vessel to Target Illegal Whaling

At a Hollywood fundraiser on Saturday night, we shared with supporters our desire to add the Ocean Adventurer to our fleet for our upcoming 2010-2011 Antarctic Whale Defense Campaign, Operation No Compromise.

The 12-year-old, 115-foot, stabilized monohull vessel would fill the role of fast interceptor, replacing the Ady Gil, the vessel that the Japanese whaling vessel Shonan Maru No. 2 deliberately rammed and destroyed on January 6th of this year.

This expedition will be our seventh campaign to oppose the illegal activities of the Japanese whaling fleet in the Southern Ocean and we hope it will be our last season. During the past six campaigns, we have saved the lives of nearly 2,000 whales and exposed illegal Japanese whaling activities to the entire world. Last season, we were able to save more whales than the Japanese whalers were able to kill. Five hundred and twenty-eight (528) whales are alive and swimming in the sea because our supporters enabled us to intervene by underwriting our ships and crews.

Each year, because of our supporters, we have become stronger and more effective. Through patience, determination and persistence, we are driving the Japanese whaling fleet into debt and closer to the day they will retreat from the Southern Ocean Whale Sanctuary.

We are confident that with your help, we will see our most effective campaign ever with Operation No Compromise. Our ships, the Steve Irwin and the Bob Barker, are currently being prepared for the campaign. We have recruited the best crew we can assemble. Our only challenge now is to raise the funds for the Ocean Adventurer.

With three ships, we will once again be able to track and intervene against the poachers in the Southern Ocean for the entire season. Our goal is to save more whales this coming season than we did during the last season and to shut down whaling in the Southern Ocean permanently.

Please help us save whales by supporting Operation No Compromise and make a donation today!

OSLO | Wed Sep 8, 2010 12:41pm EDT

OSLO (Reuters) - The world should safeguard coral reefs with networks of small no-fishing zones to confront threats such as climate change, and shift from favoring single, big protected areas, a U.N. study showed.

“People have been creating marine protected areas for decades. Most of them are totally ineffective,” Peter Sale, a leader of the study at the U.N. University’s Institute for Water, Environment and Health, told Reuters.

“You need a network of protected areas that functions well,” he said. “It’s important to get away from single protected areas which has been the common approach.”

Fish and larvae of marine creatures can swim or be carried large distances, even from large protected areas.

That means it is often best to set up a network of small no-fishing zones covering the most vulnerable reefs, with catches allowed in between. Closing big zones can be excessive for conservation and alienate fishermen who then ignore bans.

Reefs from the Pacific Ocean to the Caribbean are nurseries for fish and vital for food supplies since about 40 percent of the world’s population lives within 50 km (30 miles) of the coast.

Climate change, pollution and over-fishing are among threats to reefs. Warmer oceans can damage corals, sometimes irreversibly. The U.N. University study is in a new handbook to help planners cooperate with marine scientists.

On land, planners can usually be confident that plants and animals will stay in areas set aside as national parks, Sale said. At sea, park limits are far less relevant.

MANGROVES

In the past, he said, countries had sometimes set up large protected areas for reefs but then cleared mangroves along nearby coastlines to make way for hotels and beaches for scuba-diving tourists. That can damage some fish stocks.

“In the Caribbean, snappers and groupers spend their lives as juveniles in mangroves and sea grass beds,” Sale said. As adults the fish go back to live on the reefs, creating a need for protected zones on both reefs and in mangroves.

Scientists recently discovered that the spiny lobster, the most valuable fishery in the Caribbean, has a larval stage lasting seven months, shorter than widely believed.

Understanding ocean currents can help to show how far they get dispersed within seven months before settling on the seabed. That can also help in deciding where to site protected zones.

Sale said Australia’s Great Barrier Reef was a good example of management, with a network of no-fishing zones and others open to tourism or fishing. That system meant a balance between the needs of people and the reef.
