Richard Davies entdeckte den Riesenkalmar bei einem Strandspaziergang. Dieser war noch am Leben, allerdings scheiterte Davies mit dem Versuch, das Tier wieder ins Wasser zu schieben, erzählte der News Der Kalmar habe ein Gewicht von bis Kilogramm gehabt, dennoch wagte er einen Rettungsversuch.
Als Davies jedoch mit seinen Anstrengungen begann, saugte sich eines der Tentakel des Kalmars an seiner Hand fest, das er nur unter einiger Kraftanstrengung entfernen konnte.
Eine Rettung in Eigenleistung schien aussichtslos für den Spaziergänger. Somit benachrichtigte er die Behörden und musste den Riesenkalmar sterben lassen.
Inzwischen ist der gestrandete Riesenkalmar im Iziko Museum. Ersten Erkenntnissen zufolge war der 4,19 Meter lange Kalmar noch nicht ausgewachsen und etwa zwei Jahre alt, sagte Meeresbiologe Dr.
Wayne Florence gegenüber News Then they bring it toward the powerful beak, and shred it with the radula tongue with small, file-like teeth before it reaches the esophagus.
They are believed to be solitary hunters, as only individual giant squid have been caught in fishing nets. Although the majority of giant squid caught by trawl in New Zealand waters have been associated with the local hoki Macruronus novaezelandiae fishery, hoki do not feature in the squid's diet.
This suggests giant squid and hoki prey on the same animals. The only known predators of adult giant squid are sperm whales , but pilot whales may also feed on them.
Because sperm whales are skilled at locating giant squid, scientists have tried to observe them to study the squid. The squid had been photographed alive shortly before its death by a tourist named Javier Ondicol, and examination of its corpse by the Coordinators for the Study and Protection of Marine Species CEPESMA indicates that the squid was attacked and mortally wounded by another giant squid, losing parts of its fins, and receiving damage to its mantle, one of its gills and losing an eye.
The intact nature of the specimen indicates that the giant squid managed to escape its rival by slowly retreating to shallow water, where it died of its wounds.
The incident is the second to be documented among Architeuthis recorded in Spain, with the other occurring in Villaviciosa.
Evidence in the form of giant squid stomach contents containing beak fragments from other giant squid in Tasmania also supports the theory that the species is at least occasionally cannibalistic.
Alternatively, such squid-on-squid attacks may be a result of competition for prey. These traits are seen in the Humboldt squid as well, indicating that cannibalism in large squid may be more common than originally thought.
The taxonomy of the giant squid, as with many cephalopod genera, has long been debated. Lumpers and splitters may propose as many as eight species or as few as one.
The broadest list is:. It is unclear if these are distinct species, as no genetic or physical basis for distinguishing between them has yet been proposed.
Many species have been named in the sole genus of the family Architeuthidae, but they are so inadequately described and poorly understood that the systematics of the group is thoroughly confused.
The number of species of giant squid is not known, although the general consensus amongst researchers is that there are at least three species, one in the Atlantic Ocean Architeuthis dux , one in the Southern Ocean A.
In March , researchers at the University of Copenhagen suggested that, based on DNA research, there is only one species:  . Aristotle , who lived in the fourth century BC, described a large squid, which he called teuthus , distinguishing it from the smaller squid, the teuthis.
He mentions, "of the calamaries, the so-called teuthus is much bigger than the teuthis ; for teuthi [plural of teuthus ] have been found as much as five ells long".
Tales of giant squid have been common among mariners since ancient times, and may have led to the Norse legend of the kraken ,  a tentacled sea monster as large as an island capable of engulfing and sinking any ship.
Eyewitness accounts of other sea monsters like the sea serpent are also thought [ by whom? Steenstrup wrote a number of papers on giant squid in the s.
He first used the term "Architeuthus" this was the spelling he chose in a paper in A portion of a giant squid was secured by the French corvette Alecton in , leading to wider recognition of the genus in the scientific community.
From to , many squid were stranded on the shores of Newfoundland. For example, a specimen washed ashore in Thimble Tickle Bay , Newfoundland, on 2 November ; its mantle was reported to be 6.
Many strandings also occurred in New Zealand during the late 19th century. Although strandings continue to occur sporadically throughout the world, none have been as frequent as those at Newfoundland and New Zealand in the 19th century.
It is not known why giant squid become stranded on shore, but it may be because the distribution of deep, cold water where squid live is temporarily altered.
Many scientists who have studied squid mass strandings believe they are cyclical and predictable. Aldrich used this value to correctly predict a relatively small stranding that occurred between and In , another giant squid, later named "Archie", was caught off the coast of the Falkland Islands by a fishing trawler.
It was 8. It was put on display on 1 March at the Darwin Centre. Researchers undertook a painstaking process to preserve the body.
It was transported to England on ice aboard the trawler; then it was defrosted, which took about four days. The major difficulty was that thawing the thick mantle took much longer than the tentacles.
To prevent the tentacles from rotting , scientists covered them in ice packs, and bathed the mantle in water. Then they injected the squid with a formol-saline solution to prevent rotting.
The number of known giant squid specimens was close to in ,  and new ones are reported each year. Around 30 of these specimens are exhibited at museums and aquaria worldwide.
The search for a live Architeuthis specimen includes attempts to find live young, including larvae.
The larvae closely resemble those of Nototodarus and Onykia , but are distinguished by the shape of the mantle attachment to the head, the tentacle suckers, and the beaks.
By the turn of the 21st century, the giant squid remained one of the few extant megafauna to have never been photographed alive, either in the wild or in captivity.
Marine biologist and author Richard Ellis described it as "the most elusive image in natural history". It was captured and tied to a quay , where it died overnight.
It is on display at the National Science Museum of Japan. They used a five-ton fishing boat and only two crew members. The line also held a camera and a flash.
The camera took over photos before the squid managed to break free after four hours. The squid's 5.
Later DNA tests confirmed the animal as a giant squid. On 27 September , Kubodera and Mori released the photographs to the world. The researchers were able to locate the likely general location of giant squid by closely tailing the movements of sperm whales.
According to Kubodera, "we knew that they fed on the squid, and we knew when and how deep they dived, so we used them to lead us to the squid".
Kubodera and Mori reported their observations in the journal Proceedings of the Royal Society. Among other things, the observations demonstrate actual hunting behaviors of adult Architeuthis , a subject on which there had been much speculation.
The photographs showed an aggressive hunting pattern by the baited squid, leading to it impaling a tentacle on the bait ball's hooks. This may disprove the theory that the giant squid is a drifter which eats whatever floats by, rarely moving so as to conserve energy.
It seems the species has a much more aggressive feeding technique. In November , American explorer and diver Scott Cassell led an expedition to the Gulf of California with the aim of filming a giant squid in its natural habitat.
The team employed a novel filming method: using a Humboldt squid carrying a specially designed camera clipped to its fin. The elusive nature of the giant squid and its foreign appearance, often perceived as terrifying, have firmly established its place in the human imagination.
Representations of the giant squid have been known from early legends of the kraken through books such as Moby-Dick and Twenty Thousand Leagues Under the Sea on to novels such as Ian Fleming's Dr.
In particular, the image of a giant squid locked in battle with a sperm whale is a common one, although the squid is the whale's prey and not an equal combatant.
