Hammerhead Sharks | JONATHAN BIRD'S BLUE WORLD

Of all the animals in the oceans, the hammerhead shark may be one of the strangest looking. The exact purpose of the wide, flat head is a mystery, but several theories abound. We travel to the shark-infested waters of the Galapagos in Ecuador and to a research station in Hawaii to learn about the unusual habits of these sinister-looking sharks. Jonathan swims in schools of hundreds of hammerheads, and yet the sharks ignore him. What are the sharks up to? ********************************************************************** If you like Jonathan Bird's Blue World, don't forget to subscribe!

Scalloped Hammerheads normally live in the open ocean, but here at Darwin Island they come close to shore in large numbers. Considering the vast numbers of fish here, it would be logical to assume that the sharks come to feed. Yet, nobody has ever witnessed the sharks feeding. The Galapagos Islands are a remote archipelago 600 miles off the coast of Ecuador in the Pacific Ocean. Hammerheads are most common at the northernmost island of Darwin, famous for its stone arch. Hammerheads are of course known for their strange, flattened heads. But you have to wonder…what is that flat head for? Shark biologists put their own heads together to figure it out. At first, they speculated that it gave the hammerhead wider stereoscopic vision. But that didn’t work: hammerhead eyes face in opposite directions, meaning they can’t see in stereo. The wide head probably has nothing to do with eyesight. So maybe it has to do with the sense of smell. Wider spaced olfactory organs would help the hungry shark sniff out prey more accurately. Well, not really. Although the nostrils and olfactory organs are widely spaced, a groove along the front of the head effectively connects them together. Therefore, they don't give the hammerhead a better sense of directional smell than any other shark. Scientists finally hit upon a graceful reason for the awkward head: It helps the hammerhead turn faster by eliminating the need for large pectoral fins. Some sharks, like white tip reef sharks can rest all day if they want, just gulping water to ventilate their gills, the shark equivalent of breathing. Hammerheads, on the other hand, cannot accomplish this. Like most pelagic sharks, they must keep swimming not only to stay up off the bottom, but to breathe. In an ironic twist of fate, if a hammerhead stops swimming, it will drown. The big flat head is a wing to keep the hammerhead up off the bottom. Researcher Kanesa Duncan at the University of Hawaii is studying Scalloped hammerheads. She catches the sharks when they are just pups, only a few weeks old, in Kaneohe Bay on Oahu. By holding the shark upside down, she places it in a kind of trans called Tonic Immobility. She frequently puts the pup back in the water to aerate the gills. Once aboard the boat, she first measures the shark while an assistant records the data. Next she implants a small visual tag with a number on it through the shark’s dorsal fin. This does not hurt the shark at all. The fin is almost completely made of cartilage. Next, she weighs the pup. Back at the lab, Duncan has several captive hammerhead pups that she is working with to determine growth patterns. She wants to learn, among other things, how fast baby Hammerheads grow. But I still want to know what they are all doing at Darwin Island in the Galapagos, and I finally get a clue when I see a shark being investigated by a fish. The strong current at Darwin Island allows a hammerhead to swim in place, like a runner on a treadmill, yet hold a fixed position over the reef. King Angelfish make their homes on this reef and they serve as cleaner fish for the sharks. Because the sharks get cuts and scrapes, not to mention parasites, that need cleaning, they come to a cleaning station where a King Angelfish is waiting to clean the wounds and eat the parasites. A shark looking to be cleaned often swims at an angle, with its white belly showing. This body language tells the angelfish to come on over. Angelfish looking to clean a shark swim up and down in the water to attract the shark’s attention. Often, something seems amiss to the shark and it rebuffs the fish. The sharks feel vulnerable while they are being cleaned, so they pick a cleaning station carefully. If anything doesn’t seem right, they move on.

Oh my! Nature is absolutely wonderful! Its a cleaning station! And I never knew that the angels were cleaners! As to the broad head on the Hammerhead - I always thought that it was to increase the density of the Ampulii of Lorenzeni and thus its electrical detection capabilities......Once again, I have learned something new, on your wonderful channel.

sharks mistake a lot of things for food mainly humans thats why great white sharks attack but they don't meant to hurt you they hate the taste of human and we have too many bones and not enough meat for them so they try to leave us alone but it's hard for them to see in water so thats why sharks attack the bull shark likes the taste of human though and will eat them but just stay away and you will be fine

The wide head on a hammer head shark is not to help them swim. If this were so, other sharks like the Mako, Great white, Blue shark and other roaming sharks would all have wide flat heads. None of those sharks have any problem staying off the ocean floor. Hammer heads often feed on the bottom. The underside of their wide head is covered with tiny holes. These are special sensory organs called the Ampullae of Lorenzini. They are very sensitive to the electrical field every living creature has. The hammer heads search for prey that is hidden under the sand. They skim along the bottom moving their heads back and forth trying to detect something under the sand. It's sort of like a person using a metal detector. When a hammerhead senses a living animal under the sand it scares it out and snaps it up. The width of the head gives the shark a wider field of detection. Hammer head sharks can also eat prey swimming free in the water, but because they look for prey under the sand, they evolved that weird head.
Now, as far as I know, all predator sharks have the Ampullae of Lorenzini and they use it to detect their prey as well. But the prey of most other sharks doesn't hide under the sand, so they don't need a wide head to find their prey. Reef sharks try to find their prey hiding in holes in rocks and hard corals. They too use their ampullae to detect a fish in a hole because it's hard to see in a hole. Their heads are narrow to fit in some of the holes and get their dinner.

Sharks sense electromagnetic pulses... Hammerheads are exceptionally good at it due to their wide head where there sensors are. It's easier for them to distinguish weather movement is coming from left or right.... There's a documentary on YouTube by nat geo on it..

+Bres craft corner Depends on depth, etc. But for say an average 80 foot dive, you can get right down there very quickly, about as fast as you can clear your ears (maybe 1-2 minutes) but coming back up you must go slower to prevent bubbles from forming in your blood. The rule of thumb is to come up no faster than 1 foot every 2 seconds, with a 3 minute "safety stop" at 10-15 feet. So coming up from 80 feet (assuming no decompression obligation) takes somewhere around 6 minutes.

One thing I still don't understand is...why do we, as humans, need to know everything? Like how a Hammerhead shark grows? why does that matter? All we are doing is disrupting the natural cycle of the earth/living things. All i'm saying is we don't need to know everything and that's OK. just let animals be animals. We don't need to capture the pups and hold them captive against their will. You separated them from their home. That's not how it should be. let them be free if you really love animals.

+hiku Artifact202 For their protection, they need to be understood. This way we can determine their breeding cycles and maturity ages, as well as their feeding and behaviour patterns. If there is a threat to the shark population, these facts are crucial in protecting them. The cost of this information, a few tissue samples taken and a couple of sharks spending their youth being kept in optimal temperature water with more than enough food and no danger from bigger fish is far outweighed by the potential saving value this holds for the shark population as a whole.

i thought that the head was shaped like this so that their electromagnetic pulse detection is better. so they can more easily discover fish and rays hiding in the sand.

+BlueWorldTV could be a combination of all those things xD awesome video's btw, i really like it
BlueWorldTV
BlueWorldTV - 6 years ago
+Shadey Mcbones Theories abound and there is no question that the larger surface area of the "hammer" provides more real estate for ampullae of lorenzini, but there is no hiding the obvious fact that the head is shaped like a wing and it's most likely that the wing has something to do with it. My explanation is based on interviews with shark researchers who have long noticed that the head gives the Hammerhead an amazing ability to turn quickly that no other sharks have. It is based on the head providing both mass and lift at the front of the shark and allowing for smaller pectoral fins.

Typically a predator's eyes are in the front, but these guys seem to show otherwise... Any explanation?
Taylor Jordan
Taylor Jordan - 6 years ago
+Jade Matusow The eyes, which are on opposite sides of the hammer, are there for a very good reason. The eye placement makes the shark capable to see vertically at 360 degrees, making it extremely easy to spot things above it and below it quite easily. Hammerhead sharks often eat rays, specifically stingrays, and where do the rays live? On the ocean floor. The hammerhead shark eats the stingrays straight out of the sand, pinning them down with it's wide, flat head, but with all the upturned silt, it would be extremely difficult to see. Through adaptation, their need for frontal sight deteriorated. There is speculation that the shark sensory organs, or Ampullae of Lorenzini, are highly concentrated in a hammerhead's, well...head. Their sensors allow the shark to sense movement and very slight changes in the water from a very far distance. These sensors act like a radar would, giving the shark direct coordinates of the change in water (the presence in an organism). So, with all that said, frontal eyesight is not needed, because hammerhead sharks can "see" without really seeing. I hope this helped (:

That's a complicated question because our cameras have been changing every year.  We are now shooting on Sony Z100 4K XAVC (ultra-HD 3840x2160) cameras.  Before that we shot on the Sony PMW-200 XDCAM and EX1R.  Before that we shot on HDV tape with Sony Z1, Canon XH-A1 and Sony FX7 cameras.  Before that it was Standard def with Panasonic DVCPRO and Sony VX-1000/2000.  We started the series editing on a system called Media 100 but switched to Final Cut Pro which we used up until about 6 months ago when we switched to Adobe Premiere CC because Final Cut 7 was too old to handle the new 4K formats and I hate Final Cut X.

A nice documentary, but his final comment is wrong. The water isn't blue, it is clear and the blue sky is refracting through it to make it appear blue.

+BlueWorldTV You're quite right. I have learned something. Thank you.

It's not the sky.  Water filters light.  Longer wavelengths (like red) do not penetrate very far into water, but shorter wavelengths do.  So if you get enough water together (i.e. a pool or the ocean) it actually does appear blue due to which wavelengths of light are absorbed and which are re-emitted.  Anything that appears a color is that color for all effective purposes.  The sky has nothing to do with it.  The ocean is still blue when the sky is cloudy.

+BlueWorldTV Oh good, you agree that seawater isn't blue. If you took a glass of seawater into a room, the water would be clear, at best, not blue.

5 minutes in the video the narrator says "putting the sharks upside down puts it in a trance state - no one knows why" actually we do now know why... these sharks need to be upright or they get disoriented, with humans its like spinning around in circles and getting extremely dizzy..octopus have been filmed grappling great white sharks and turning them upside down until they drown..killer whales do the same thing by knocking into them and biting them to hold them like that :)
