Greenland Sharks: Christina Karliczek about cold-water sharks

Christina Karliczek about cold-water sharks

Greenland Cold-Water sharks

Sharks have done it to me especially

Christina Karliczek works as a camera woman and shoots underwater animal films. Most recently, she spent four years filming cold-water sharks – including the ice shark. It’s rare and can live for over 500 years.

Christina Karliczek can still remember when she saw her first shark. She was on a boat off the South African coast at the time. And then this six-meter-long great white shark dove through the water. It was an impressive experience, because the shark was about the same length as the boat Christina was in. “It almost took my breath away how big this shark was,” she says.

“My first shark was a great white in South Africa. And I almost fell over then – because of the sheer size.”

Christina Karliczek is a cinematographer specializing in the underwater world. She says, “It’s so exciting to show these animals in their environment, because from the surface we see almost nothing.” Learning more about the animals that live underwater and being able to show others this world – that’s what drives her in her work, she says.

She is particularly fond of sharks. The wildlife filmmaker finds it fascinating what strategies sharks have developed over millions of years to hunt prey – and thus stay at the top of the food chain in the oceans. “The diversity of shark species is incredible,” Christina says.

“Many of these species live much deeper in the oceans.”

While some sharks in tropical regions can often be encountered close to the surface, there’s a very different challenge with cold-water sharks: Generally, it’s not as easy to film in colder regions of the oceans because teams need much more equipment and protection against the cold. In addition, the sharks here often live at depth. “It goes down to 2,000 meters,” says Christian Karliczek.

512 years – Greenland shark oldest shark in the world?
Video Transcript

Researchers have found an ancient shark in the North Atlantic
Believed to be 512 years old which could be the oldest living vertebrate in the world
Greenland sharks are relatively ugly and bizarre-looking creatures
It has a long thick gray body and its small head consists of a short rounded snout
With ghostly eyes and a ever gaping mouth the species is often plagued by worm-like
parasites that latch on to their eyes
Marine biologist Julius Nilsson and his team have been studying an 18-foot Greenland shark. They believe. It’s at least
272 years old and possibly as old as
512 years
Greenland sharks have been known to live for hundreds of years and spend most of their lives swimming around looking for a mate
But the recent research proves that this species of shark could live to be even older
Researchers are looking to how Greenland sharks long life
Genes could shed light on what determines life expectancy in different species including humans
So how did this shark reach this age well Greenland sharks are found in the deep water of the Atlantic Ocean?
From Canada to Norway the answer likely has to do with a very slow metabolism and the cold waters that they inhabit
The method to discover the age of the animal was determined last year
Researchers found a way to predict age by analyzing the lens and cornea of the eye
Which they believed linked size with age?
Greenland sharks also known as Garry sharks
Or gray sharks grow at a rate of 1 centimeter a year
Enabling scientists to determine their age by measuring their size
This particular shark was measured at 18 feet in length and weighed over a ton by measuring the size of the shark
researchers suggest the animal could been born as early as
1505
Making it even older than Shakespeare. With an estimated age of 512 years old
makes this creature
Extraordinary, and it should be considered among the absolute oldest animals in the world
I’m gonna put a list of historical events that happened over the last
512 years in the show more section of this video that this shark was a life form
Saying an age of five hundred and twelve years old does not really sink in until you realize it was alive when
European settlers arrived on the American mainland of Panama in 1508
Anyway, that’s the end of this video. Thanks for watching, and we’ll see you next time. B-Bye.

No creature lives to be as old as Greenland sharks

There is one species of shark that even lives under the ice in the polar regions: the Greenland shark, or ice shark. “This is the ultimate cold-water shark,” says Christina Karliczek. For her film, she was determined to find and film such a specimen. “This shark species can live up to 512 years. That’s an absolute record number,” says the wildlife filmmaker. It took a long time, but she finally got lucky and got an ice shark in front of her camera. Her film “Erlebnis Erde: Eiskalte Haie!” is currently still available in the ARD media library.

“Sometimes I can only really process the experience afterwards, because then I see it on the monitor – and it only really works then.”

What sharks live in cold water?

Amazingly several species of polar sharks — like polar bears and penguins — have adapted to live in icy cold waters where the temperature does not rise above 5° C (41° F). These include the Greenland sleeper shark, the pacific sleeper shark and the black dogfish shark.

Do great white sharks live in cold water?

The white shark is a fearsome predator, well adapted to live in cold water, where food is more abundant. It is far from a “primitive” cold-blooded fish but is actually a highly evolved warm-blooded animal.

What water temp do great white sharks like?

Great white sharks live in almost all coastal and offshore waters which have water temperature between 12 and 24 °C (54 and 75 °F), with greater concentrations in the United States (Northeast and California), South Africa, Japan, Oceania, Chile, and the Mediterranean including Sea of Marmara and Bosphorus.

Do all sharks live in cold water?

Sharks are no different. Each species has a temperature range that makes them most comfortable, whether that’s the warm waters of the tropics, the cold waters around the North and South Poles, or anywhere in between. … Some sharks may be able to adapt.

What ocean has the most sharks?

Atlantic Ocean
In 2018, the United States led the world with the highest number of reported shark attacks, according to the ISAF. Within the continental United States, more shark-human incidents occurred in the Atlantic Ocean—only four attacks were reported in the Pacific (three from Hawaii) compared to 27 in the Atlantic.
