Ezinye izilwanyana ezityhefayo

Siyatyhefa xa sityiwaSitya: InyamaSiyatyhefa, asinatyhefu yokuluma okanye yokuhlaba

Ingozi ebantwini: KubuhlunguKunokuba buhlungu ngokwenene, kodwa phantse akusoze kube kubi kakhulu.

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

Siyatyhefa okanye sinetyhefu? Izilwanyana ezinetyhefu zitofa ityhefu ngokuluma okanye ngokuhlaba. Izilwanyana ezityhefayo ziyingozi xa uzichukumisa okanye uzitya. Esi siyatyhefa.

Sihlala

North Atlantic and Arctic Oceans1

uLwandlekazi lweArctic, uLwandlekazi lweAtlantiki

Ekhaya

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

Ubude

4 m ukuya ku-6,4 m (13 ft ukuya ku-21 ft)1

Ubunzima

1023 kg (2255 lb)1

malunga ne-2,6 km/h (1,6 mph)

Ukuqubha: omnye wookrebe abacotha kakhulu abakhe balinganiswa

Sitya ntoni?

It is both a scavenger and an active predator, eating fish, seals, squid and sometimes small whales. It may ambush seals while they are asleep, and it uses suction to draw prey into its mouth. It also eats carrion.1

Indlela yokusiqaphela

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

Amandla etyhefu

Siyatyhefa xa sityiwa

Siyingozi kuphela ukuba kukho into esityayo.

Ityhefu yaso etyhefayo (xa usichukumisa okanye usitya) yenza ntoni?

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?

Ingozi ebantwini: KubuhlunguKunokuba buhlungu ngokwenene, kodwa phantse akusoze kube kubi kakhulu.

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

Senza ntoni xa soyika?

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

Ukuba umntu usichukumisile okanye usityile

Ukuba umntu usityile okanye uneempawu emva kokusitya: tsalela inombolo kaxakeka okanye iziko lezityhefu (poison centre) ngoko nangoko.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
Ukuba usichukumisile okanye usityile: musa ukukhuhla amehlo okanye umlomo wakho, hlamba izandla zakho kwaye ufumane uncedo lwezonyango.

Asikuzingeli. Ityhefu yaso ikhona nje ukuze kungabikho nto isityayo. Okungakumbi malunga nokuhlala ukhuselekile

kufanelekile ukwazi

Iinyaniso

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

Umqhekezi weentsomi

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

Inyaniso: 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
