Greenland shark
The Greenland shark is a huge, slow shark that lives in the cold, deep waters of the North Atlantic and Arctic Oceans. It is famous for living longer than any known vertebrate (animal with a backbone). Its flesh is poisonous to eat unless it is specially prepared.1

Ako ho spoznať
- A thickset, heavy body with a short, rounded snout1
- Small eyes and small dorsal and pectoral fins1
- Five very small gill openings for its size1
- Colour ranges from pale creamy-grey to blackish-brown, usually uniform, sometimes with whitish spots or faint dark streaks on the back1
- Often has small parasitic copepods (crustaceans) attached to its eyes1
Sila toxínu
Škodí, iba ak ho niečo zje.
Čo robí jeho toxín?
The shark is not venomous. Its meat is poisonous to mammals because it contains high levels of trimethylamine N-oxide (TMAO), a natural chemical that makes the flesh toxic.1
Aké nebezpečné je pre ľudí?
Nebezpečenstvo pre ľudí: BolestivéMôže to poriadne bolieť, ale skoro nikdy to nie je vážne.Greenland sharks are not considered a threat to people, because they live deep in remote, cold waters. Only one possible attack is recorded, in 1936, and it was never linked to this species. One unverified report from around 1859 describes a human leg found in a shark's stomach.1
Čo robí, keď sa bojí?
When hauled onto a boat, it thrashes its tail so violently that it is dangerous to stand near it, and its muscles can still twitch after death.1
Ak sa ho niekto dotkol alebo ho zjedol
- Ak ho niekto zjedol alebo má po zjedení príznaky: hneď volaj tiesňovú linku alebo toxikologické centrum.
Vždy najprv zavolaj na tiesňovú linku (112, 000, 911). Toto sú všeobecné rady prvej pomoci, nie lekárska rada. Základy prvej pomoci
Buď v bezpečí
- Nikdy sa nedotýkaj divého zvieraťa, nechytaj ho ani ho nedráždi, aj keď je malé a aj keď vyzerá, že spí alebo je mŕtve.
- Nechaj mu priestor. Ak nejaké stretneš, zostaň pokojný, pomaly cúvni a nechaj ho ísť svojou cestou.
- Ak si sa ho dotkol alebo si ho zjedol: nešúchaj si oči ani ústa, umy si ruky a vyhľadaj lekársku pomoc.
Nejde po tebe. Jeho toxín je tam len na to, aby ho nikto nezjedol. Viac o tom, ako zostať v bezpečí

Fakty
It is thought to have the longest lifespan of any known vertebrate, estimated at between 272 and 510 years.1
It is one of the slowest-swimming fish for its size, with a fastest cruising speed of about 2.7 km/h.1
Parasitic copepods often attach to its eyes and can damage them, but this does not seem to shorten its life, because it relies mainly on smell and hearing.1
It is one of the largest shark species alive, with the largest confirmed specimen weighing around 1,023 kg.1
In Iceland, a specially treated form of its meat is eaten as a pungent delicacy called kæstur hákarl.1
Its slow metabolism is thought to be linked to its very long life, although this is still a hypothesis.1
Lovec mýtov
Mýtus: The Greenland shark is a dangerous threat to humans.
Pravda: It is not considered a threat to people. It lives deep in cold, remote waters, and the only report of a possible attack was never confirmed as this species.1
