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

Com reconèixer-lo
- 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

Només és perjudicial si alguna cosa se'l menja.
Què fan les seves toxines?
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
Com de perillós és per a les persones?
Perill per a les persones: DolorósPot fer molt de mal, però gairebé mai no és greu.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
Què fa quan té por?
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
Si algú l'ha tocat o se l'ha menjat
- Si algú se l'ha menjat o té símptomes després de menjar-se'l: truca de seguida al número d'emergències o al centre de toxicologia.
Truca sempre primer al número d'emergències (112, 000, 911). Això són pautes generals de primers auxilis, no consells mèdics. Primers auxilis bàsics
Estigues segur
- No toquis, atrapis ni molestis mai un animal salvatge, encara que sigui petit i encara que sembli adormit o mort.
- Deixa-li espai. Si en trobes un, mantén la calma, recula a poc a poc i deixa que segueixi el seu camí.
- Si l'has tocat o te l'has menjat: no et freguis els ulls ni la boca, renta't les mans i busca ajuda mèdica.
No va a per tu. Les seves toxines només hi són perquè ningú no se'l mengi. Més sobre com estar segur

Dades
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
Desmuntamites
Mite: The Greenland shark is a dangerous threat to humans.
Veritat: 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
