(Bloch & Schneider, 1801)
The ice shark, also known as the Greenland shark, is a shark from the spiny dogfish order (Squaliformes).
It is not of aquaristic interest, and not only because of its size of up to 7 meters.
Greenland sharks have an average life expectancy of at least 250 years, but can also live to be over 500 years old, making them probably the longest-living vertebrates in the world.
The body of the ice shark is torpedo-shaped! Its coloration is grey-brown / olive green, weight up to 2500 kg.
The Greenland or ice shark feeds on seals and larger fish, and there is at least one report of a large polar bear being found in the stomach of the ice shark.
Both eyes of the Greenland shark are often covered with bioluminescent copepods (Copepoda: Ommatokota elongata).
It is not known whether they harm or benefit the shark. There are explanations for both possibilities: one theory says that they paralyze the eyes and even blind the sharks. Another theory assumes that the copepods are luminescent, act like fishing rods and thus “bait” the sharks with food.

Shark bites can be quite lethal to humans, especially the 10 most dangerous shark species are considered and can launch unprovoked attacks from humans: - Great white shark - Bull shark - Tiger shark - Sand tiger shark - Blacktip shark - Bronze shark - Spinner shark - Blue shark - Hammerhead shark - Whitetip shark The bite by a shark is one of the most basic fears of humans, but the number of deaths caused by shark attacks is very low: in 2015 there were 98 attacks by sharks and in 6 cases the attack resulted in a fatal end for humans. In 2016 there were 107 attacks by sharks and in 8 cases the attack resulted in a fatal end for humans.

In 2022, there were a total of 108 shark attacks in the USA.
Conversely, however, 100 million sharks were killed by humans. http://www.zeit.de/2016/37/haie-toetung-tierschutz-surfer The risk of being bitten by a shark varies greatly from region to region, with most attacks occurring in Florida, Australia and South Africa. Please be careful not to go into the water with bleeding skin wounds, heed bathing warnings from the authorities and be very careful when using surfboards, as sharks can easily confuse the boards with seals and harbour seals. After shark bites, always call a doctor or / and the rescue service as soon as possible, as heavy bleeding can be life-threatening.
