One hypothesis for how giant squid evolved to grow so enormous is that the tremendous size leaves it with few predators in the deep water.
However, those predators still exist—most notably the sperm whale. Scientists have found giant squid beaks, as well as other undigested pieces of giant squid, in the stomachs of sperm whales—the remains of a very large serving of calamari.
Additionally, beach-stranded sperm whales have been found with sucker marks on their skin, battle scars large enough that only a giant squid could have caused them. Who wins in these battles? It's hard to know, since these duels have never been seen by people, but most likely the sperm whales emerge victorious. The small sampling of giant squid stomachs have never contained any recognizable sperm whale parts, but many sperm whale stomachs have contained giant squid.
And the only way a whale develops a battle scar is if it survives the battle. Clyde Roper grew up close to the ocean and was a lobster fisherman before going to graduate school, where he studied squid. Roper is especially passionate about giant squid and has traveled the world studying dead specimens on beaches and in museums and searching for living squid. In his quest to learn as much as possible about giant squid, Roper has been bitten by several species of squids and tasted a piece of cooked giant squid.
It was probably years old and, when alive, 11 meters 36 feet long with tentacles that extended 6. Since then it has shrunk considerably, but at 7. How do you transport a giant squid carcass from Spain to Washington, D. With the help of the U. Navy and U. Air Force for Operation Calamari. The tanks hold between 1, and 1, gallons of water, are completely airtight, contain valves and openings for refilling preservative fluid when necessary and taking tissue samples, and are equipped with appropriate gear for anchoring all body parts and tentacles to prevent floating.
International shipping regulations prohibit transportation of hazardous materials in an airplane. The squids could not begin their journey until their tanks were completely finished and ready to receive them.
Once that was done the specimens were wrapped carefully in cheesecloth and crated tightly for their trip. Several squid specialists accompanied them on their flight and as soon as they arrived, they were met by Smithsonian personnel and immediately installed into their new quarters at the ocean hall.
It already totals about , preserved specimens collected worldwide—including the most diverse collection of squids found in the world. Holotypes are the specimens that were used by scientists to formally describe and name a new species. If you want to see a live giant squid, you have to go to where it lives. Clyde Roper, a Smithsonian zoologist, has tried several techniques to track down giant squid in their natural habitat. With help from the National Geographic Society, he attached a small video camera called Crittercam to the heads of sperm whales.
He sent a camera-equipped, robotic submersible called an Autonomous Underwater Vehicle to search for giant squid. And he has dived thousands of feet alone in a deep sea submersible. So far, no luck for Dr. But researchers in Japan were able to film a giant squid in its natural habitat in using flashing lights to imitate bioluminescent jellies Watch the footage at the Discovery Channel. In the giant squid made an appearance again, this time off the coast of Louisiana.
The giant squid has captured the human imagination for more than 2, years. Were they monsters or sea serpents? Rare glimpses of this huge sea creature inspired both fear and fascination. People came up with fantastic explanations for what their astonished eyes saw—or thought they saw. Movies, books, and popular lore featured encounters with huge, hungry sea creatures brandishing many tentacles. It turns out that the giant squid of myth is not a monster at all.
But only since the late 19th century has enough scientific evidence accumulated to replace the myths with fact. The first known record of Architeuthis comes from Denmark in the s, when several "curious fish" were found afloat by the sea. Historians of the time did not associate these "fish" with cephalopods; instead, they conflated their looks with those of humans, describing these creatures as having "a head like a man Not until the mids did the leading cephalopod specialist of the day, Professor Japetus Steenstrup of Denmark, conclude that the mythical beasts were, in fact, very large squid.
With the two long feeding tentacles arranged just right, they could be mistaken for arms sticking out of the mantle. The rest of the Sea Monk descriptions, however, he ascribed to a combination of astonishment and imagination. Harvey immediately displayed it in his living room, draping the head and arms over the sponge bath for easy observation. It was the first complete giant squid specimen ever put on display, and it became a turning point in our understanding of giant squid.
Professor A. Even before Harvey's giant squid carcass made the news, fiction writers had been incorporating Architeuthis into their stories. Perhaps most famously, French author Jules Vernes's novel 20, Leagues Under the Sea features a monster squid with a hunger for human flesh. A "poulpe" -- French for "octopus" but commonly translated as "giant squid" -- attacks the submarine Nautilus , putting up quite a fight and devouring a crew member.
Verne describes the foot squid as "a terrible monster worthy of all the legends about such creatures" and, in the process, created a legend himself.
For the film version of the novel, Disney created a two-ton model squid, requiring 16 men to operate the remote controls and 50 more to move the wires attached to tentacles. Their model squid pales in comparison to modern day film monsters, but it earned the movie an Academy Award for special effects.
Other diving mammals including the southern elephant seal and large Southern Ocean predators feed on juvenile colossal squid, but the sperm whale is the only species known to take adults. Specific mating behaviors are unknown in this species, but it reproduces via internal fertilization. Colossal squid are only rarely captured in deep-sea fisheries targeting other species. In almost every case, they have been captured trying to feed on hooked fishes rather than in nets.
This species is not targeted commercially and is likely naturally rare. In a recent analysis, scientists reported that the colossal squid is a species of least concern. As it is an important prey species for charismatic, protected species like sperm whales and southern elephant seals, it is vital that scientists determine its population trends and continue to study its biology and ecology.
