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

Velenoso ou pezoñento? Os animais pezoñentos inxectan a súa pezoña cunha mordedura ou unha picadura. Os animais velenosos son perigosos ao tocalos ou ao comelos. Este é velenoso.

Inicio
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

Que come?
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

Poder do veleno

Velenoso se se come

Só é perigoso se algo o come.

Que fai o seu veleno?

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

Que perigoso é para as persoas?

Perigo para as persoas: DolorosoPode doer moito, pero case nunca é grave.

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

Que fai cando ten medo?

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

Se alguén o tocou ou o comeu

  • Se alguén o comeu ou ten síntomas despois de comelo: chama de inmediato ao teu número de emerxencias ou ao centro de toxicoloxía.

Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos

Mantente a salvo

  • Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
  • Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
  • Se o tocaches ou o comiches: non esfregues os ollos nin a boca, lava as mans e busca axuda médica.

Non vai a por ti. O seu veleno só está aí para que ninguén o coma. Máis sobre como estar a salvo

Datos

1

It is thought to have the longest lifespan of any known vertebrate, estimated at between 272 and 510 years.1

2

It is one of the slowest-swimming fish for its size, with a fastest cruising speed of about 2.7 km/h.1

3

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

4

It is one of the largest shark species alive, with the largest confirmed specimen weighing around 1,023 kg.1

5

In Iceland, a specially treated form of its meat is eaten as a pungent delicacy called kæstur hákarl.1

6

Its slow metabolism is thought to be linked to its very long life, although this is still a hypothesis.1

Desmontamitos

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

Verdade: 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
