Kraken
Aliases: Hafgufa · Colossal octopus / Territory: Norvège, Islande
The Norse sea monster whose real core is identified: the giant squid Architeuthis, described in 1857 and filmed alive in 2004.
Before it was a movie monster, the kraken was working folklore among Scandinavian seafarers. Thirteenth-century Norse texts — the Konungs skuggsjá, a Norwegian king's mirror, and the saga of Örvar-Oddr — already tell of sea beasts so vast that sailors mistake them for islands, the hafgufa and the lyngbakr. The modern name arrives in 1752-1753, when Erik Pontoppidan, bishop of Bergen, gives the 'kraken' a chapter of his natural history of Norway: a back broad as a cluster of islets, arms able to drag down a ship, a fatal whirlpool when it sounds — and fish schooling so thickly above it that crews spoke of 'fishing over the kraken'.
The nineteenth century turned the tale into taxonomy. In 1857 the Danish naturalist Japetus Steenstrup assembled stranded beaks and old accounts into a formal description of a real giant cephalopod: Architeuthis dux, the giant squid. In 1861 the crew of the French dispatch vessel Alecton grappled with a dying specimen off Tenerife and salvaged only a fragment; their commander's report to the Académie des sciences met open doubt. Then a run of strandings on Newfoundland's shores in the 1870s finally delivered complete bodies, and the monster acquired measurements and a Latin name.
Seeing one alive took far longer. Not until 2004 did Tsunemi Kubodera and Kyoichi Mori photograph a giant squid hunting at a depth of 900 metres off Japan's Ogasawara Islands, and not until 2012 was one filmed in its deep habitat. The real animal reaches 12 to 13 metres including tentacles — nothing like Pontoppidan's living islands, yet formidable enough that sperm whales carry circular sucker scars from their battles.
The kraken is cryptozoology's best-case scenario: a maritime legend whose kernel matched a genuine animal unknown to science when the stories were told. The excesses — island size, sunken ships, whirlpools — are folkloric accretion: no shipwreck has ever been credibly attributed to a cephalopod, and a squid at the surface is usually a squid that is dying. The literary kraken, from Tennyson's sonnet to pirate cinema, now sails on independently of zoology.
+ Notable reports
// Norway
The Konungs skuggsjá describes the hafgufa, a sea creature so enormous that sailors mistake it for an island — the oldest written layer of the legend.
// Bergen, Norway
Bishop Erik Pontoppidan compiles fishermen's testimony in his natural history: an immense back, ship-seizing arms, a whirlpool when it dives. His chapter fixes the kraken in European imagination.
// Off Tenerife
The crew of the French vessel Alecton tries to haul a dying giant squid aboard and saves only a fragment. Commander Bouyer's report to the French Academy of Sciences is initially disbelieved.
// Ogasawara Islands, Japan
Tsunemi Kubodera and Kyoichi Mori take the first photographs of a living Architeuthis, hunting at around 900 m — the legend finally has a documented face.
+ Leading rational explanations
- Strandings and carcasses of giant squid (Architeuthis dux), the source of tales of monstrous arms
- Surface battles between sperm whales and large squid, misread from ships' decks
- Floating whale carcasses and gas upwellings mistaken for moving islands
- Folkloric accretion: each literary retelling, from Pontoppidan to adventure fiction, enlarged the beast
Status note
Class 4: a case largely closed by zoological identification — the legend's core matches the giant squid, described in 1857 and observed alive since 2004; only the folkloric excesses (living island, sunken ships) remain unsupported, and no hoax needed exposing.
+ Frequently asked questions
- Was the kraken real?
- The island-sized monster of legend, no. But the animal behind the stories is real: the giant squid Architeuthis dux, scientifically described in 1857 and first photographed alive in 2004. It is one of the rare sea legends that turned out to wrap an actual species.
- How big does a giant squid get?
- The largest females reach roughly 12 to 13 metres including the feeding tentacles, with a mantle of 2 to 3 metres. The Antarctic colossal squid is heavier but shorter. Nothing approaches the mile-wide creature of the old accounts.
- Could a giant squid sink a ship?
- No documented sinking has ever been credibly attributed to one. The animal lives at depths of 300 to 1,000 metres, and individuals seen at the surface are usually dying. Attack stories belong to folklore and misinterpretation, not the record.
