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

It lives in cold deep water, usually between 100 and 1,200 metres down, where temperatures range from -1.1 to 7.4 °C. In winter it gathers in shallower water for warmth. It is sometimes seen around fishing boats and herds of seals, where it is drawn by the smell of rotting meat.1

Ushevu waso wenzani?

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

Siyingozi kangakanani ebantwini?

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

Senzani uma sesabile?

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

Uma umuntu esithintile noma esidlile

Uma umuntu esidlile noma enezimpawu ngemva kokusidla: shayela inombolo yezimo eziphuthumayo noma isikhungo soshevu (poison centre) ngokushesha.

Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala

Hlala uphephile

Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
Uma usithintile noma usidlile: ungahlikihli amehlo noma umlomo wakho, geza izandla zakho futhi uthole usizo lwezokwelapha.

Asikuzingeli wena. Ushevu waso ukhona nje ukuze kungabikho okusidlayo. Okwengeziwe mayelana nokuhlala uphephile

Amaqiniso

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

Umqothuli wezinganekwane

Inganekwane: The Greenland shark is a dangerous threat to humans.

Iqiniso: 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
