History of the Giant Squid
The giant squid is one of the monstrous creatures still alive and always alluring many researchers around the world but till this time seems more mystifying as none of the giant squids are captured alive and the research is based on the corpses which are washed ashore. This has led the scientists and researchers to study this mammoth sea creature from the carcasses washed ashore. With limited samples, the researchers have been able to know some amazing facts about this mammoth sea creature and one such aspect is its intelligence. Yes! The giant squids are intelligent creatures and it is no myth. Most of the giant squid are highly intelligent and at times very gentle There is an alien intelligence existing beneath the deep waters, a bizarre life form that appears to be breeding by the hundreds in cold black waters far below the surface. This intelligence resides in the giant squids that have three hearts, primate-like stereoscopic eyes, blue blood and brains large enough to suggest they are among the smartest creatures on earth.
The squid has a large head and a relatively large brain. Its body, stiffened by an interior cartilaginous skeleton, is spherical or cigar-shaped, with two lateral fins. Around the mouth are eight sucker-bearing arms and two contractile tentacles with spatulate tips; on the latter are four rows of suction cups encircled by rings of chitinous (horny) hooks. The contractile tentacles, longer than the rest, are used to seize the prey and pass it to the shorter arms, which hold it to be torn by strong jaws shaped like a parrot's beak. Squid can swim faster than any other invertebrate by rapidly expelling water from the mantle cavity through the "funnel," which can be turned to direct movement. Many deep-sea squid are bioluminescent. They shoot out a cloud of dark ink when pursued; one genus secretes luminescent ink.
Giant squid, along with their cousin, the colossal squid, have the largest eyes in the animal kingdom, measuring some 10 inches (25 centimeters) in diameter. These massive organs allow them to detect objects in the lightless depths where most other animals would see nothing.
Giant Squid Fun Facts
1) The scientific name of giant squid is "Architeuthis dux". The giant squid is found in the Northern Atlantic Ocean, Gulf of Mexico, Northern Pacific ocean, Sea of Japan, Bering Sea and in the Southern Ocean. Its presence is also found in Hawaii and California.
2) The female giant squid, is larger in size than the male squid.
3) Another interesting factor about the giant squid is the eight arms it has which can grow up to 3 meters in length, but eventually none of them are used to grab prey.
4) On records the largest squid found is Largest recorded giant squid was a female that washed ashore on a New Zealand beach in 1887 18 meters long (59.5 feet).
5) The common squid is a carnivorous mollusk belonging to the same class as the nautilus, cuttlefish, and octopus.
6) In fact, they are known as the largest invertebrate out there.
7) They can grow to be close to 43 feet long when you are talking about the females. For the males, they are generally about 33 feet in length.
8) In fact, they are considered to be one of the forms of aquatic life that the most research still needs to be done about.
9) Many people out there don't even believe that they are real creatures, but merely a myth.
10) As a squid moves through the water, they stretch in the mantel area. This is going to force water to be moved through the funnel.
The Monster Colossal Squid
Measuring longer than a school bus and sporting tentacles covered in razor-sharp hooks, the colossal squid is the stuff of nightmares. However, new research suggests the enormous sea creature may not be the fierce hunter of legend. This finding not only upends science's understanding of the squid itself, but forces a reevaluation of its role in the entire ecosystem where it lives some 3,000 to 6,000 feet (914 to 1,830 meters) beneath the Antarctic sea.
Marine biologists Rui Rosa, of the University of Lisboa, Portugal, and Brad Seibel, of the University of Rhode Island, looked at the relationship between metabolism (how the body's cells turn food into energy) and body size for smaller squids in the same family and used the information to predict the metabolism of the colossal squid (Mesonychoteuthis hamiltoni).
The two marine biologists found, the squid had a slower metabolism and so moved slower than expected, waiting for prey, rather than running it down. Contrary to the image of Kraken attacking ships and dragging sailors to their deaths, the colossal squid would wait to ambush passing fish.
Rosa also noted that since so little is known about the colossal squid, almost any new discoveries are likely to overturn existing theories. The fact that the squid lives in such deep and frigid waters makes it almost impossible for scientists to acquire new specimens.
