You may have heard about the Greenland shark, but do you know everything you need to know about this incredible creature? Despite their slow metabolism, Greenland sharks are known to be incredibly slow swimmers. Because of this, they are often unable to reach a full speed of 1.8 mph. In fact, scientists were never able to age one of these magnificent creatures. Their slow metabolism and lack of tree-ring-like structures made it nearly impossible to date their life spans.
The reason why these sharks can’t see at all is due to their parasite that lives on their eye. This copepod is related to lobsters and crabs, and burrows into their eye. This causes the Greenland shark to be blind, but it can still distinguish light from dark. In fact, because of this, Greenland predators don’t need much vision when diving deep into the sea.
The Greenland shark’s population is estimated to be small, with a doubling time of about 14 years. However, it is a popular subject in science and is the support of the fisheries in Iceland, Canada, and Norway. Its liver oil is highly sought after. The World Conservation Union, an organization of countries that monitors species, lists this species as Near Threatened.
The Greenland shark is a large, cylindrical fish, with a distinct caudal keel and a slender body. It has two large spiracles above its eyes and has a surprisingly small head for a shark. Its skin color varies – from black and brown to a combination of black and grey. The rostrum is white or whitish, and is a sign of repeated abrasion. These creatures are often foraging, which makes them an ideal meal for seals.
The Greenland shark lives in shallow water and is often considered a top predator. It is considered to be the largest shark in the world. The habitat of this majestic species is cold enough to prevent common swimmers from catching one. The population of this amazing fish is estimated at around 1200m. While the Greenland shark has been reported to feed on sperm whales, it is still largely unknown.
Despite its name, the Greenland shark’s distribution is much more widespread than its name would suggest. In addition to its home in Greenland, it can also be found in cold-current coastlines of Portugal, Canada, and France. While its name suggests that it is primarily found in the cold-current region of Europe. But its geographic range is far wider than its location. Its range extends well beyond the waters of its namesake.
A Greenland shark is not blind, but it does have a parasite attached to one of its eyes. This organism, known as Ommatokoita elongata, burrows into the eye and renders the fish completely blind. Although the parasite does not impair its vision, it does not allow the Greenland shark to see light. It does not need keen vision for survival in its habitat, but it does use it to hunt for prey.
The Greenland shark has a swollen, cylindrical body with a distinct caudal keel. It also has a large, spiky head. It is a top predator in the North Atlantic, and is one of the biggest fish species in the Arctic. But, it does not eat people. It eats small fishes, mainly in kelp.
The Greenland shark’s name is not the only interesting thing about this fish. Its appearance is the main attraction of the shark. You may be curious to know how to spot it. If you have the courage to brave the cold waters, you can catch a Greenland shark. It’s a common sighting in the Atlantic. This article will give you information on how to recognize it.
