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

Anadunga sumu au ana sumu ya kugusa? Wanyama wanaodunga sumu huingiza sumu kwa kuuma au kudunga. Wanyama wenye sumu ya kugusa au kula hudhuru wakiguswa au kuliwa. Huyu ni wa aina ya pili.

Anaishi

North Atlantic and Arctic Oceans1

Bahari ya Aktiki, Bahari ya Atlantiki

Nyumbani

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

Urefu

4 m hadi 6.4 m (13 ft hadi 21 ft)1

Uzito

1023 kg (2255 lb)1

Kasi ya juu

takriban km 2.6 kwa saa (maili 1.6 kwa saa)

Kuogelea: mmoja wa papa wa polepole zaidi waliowahi kupimwa

Hula nini?

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

Nguvu ya sumu

Sumu akiliwa

Ni hatari tu kitu kikimla.

Sumu yake hufanya nini?

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

Ana hatari gani kwa watu?

Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.

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

Hufanya nini akiogopa?

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

Mtu akimgusa au kumla

Mtu akimla au akipata dalili baada ya kumla: piga namba ya dharura au kituo cha taarifa za sumu mara moja.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Ukimgusa au kumla: usisugue macho wala mdomo, nawa mikono na utafute msaada wa kitabibu.

Hakuwindi wewe. Sumu yake ipo tu ili asiliwe na yeyote. Zaidi kuhusu kukaa salama

Ukweli

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

Kuvunja dhana potofu

Dhana potofu: The Greenland shark is a dangerous threat to humans.

Ukweli: 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
