Only the Colossal Squid grows slightly larger. But after years of searching, in 2012 a group of scientists from Japan's National Science Museum along with colleagues from Japanese public broadcaster NHK and the Discovery Channel filmed a giant squid in its natural habitat for the first time. Some are surprisingly tiny—only about 1 inch (2.5 centimeters) in length. In addition to their foot-wide eyes, which help them to absorb as much light as possible to glimpse prey, they also have long feeding tentacles.

"Those animals aroused still greater astonishment in earlier times.". Giant squid are big—but just how big are they?

According to National Geographic, the largest squid ever found measured 59 feet long and weighed about a ton. The much smaller males are believed to grow to about 33 feet (10 meters). So far, no luck for Dr. Roper. Unfortunately, the reports of their size are often exaggerated since finding a live giant squid is an extremely rare event.

Since the ocean giants live at least 1,000 feet below the surface of the water, much of their observation has been done by studying specimens that have washed ashore. This is due to the overall design of their bodies. Most have ink sacs. These feeding tentacles are very long, often doubling the total length of the giant squid on their own. The Smithsonian doesn't just house giant squid; scientists at the Smithsonian’s National Museum of Natural History are building a National Cephalopod Collection. Once prey is caught by the suckers and teeth on the feeding tentacles, the squid will rein it in and bring it towards its beak with its eight arms.

Because tentacles and arms fall off or, alternatively, can be stretched out, scientists often use mantle length as the best measure of a squid's actual size. Displaying specimens of this size is a challenge―so much so that specially designed tanks had to be designed. This female (the bigger of the two) was caught in a fisherman’s net off the coast of Spain in 2005. Secondly, this astounding animal achieves its enormous size through the principle of deep-sea gigantism. Giant squid males don't use a modified arm (hectocotylus) to transfer sperm like most squid; instead, the spermatophore (sperm packet) is expelled from a penis, which sticks out through the funnel and can be as long as the animal's mantle, up to 7 feet long.

It already totals about 200,000 preserved specimens collected worldwide—including the most diverse collection of squids found in the world. The tanks hold between 1,500 and 1,800 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. They commonly wash up on the shores of New Zealand and Pacific islands, make frequent appearances on the east and west sides of the Northern Atlantic, and the South Atlantic along the southern coast of Africa. But a few survive -- and within a few years, they become giant marine predators. However, those predators still exist—most notably the sperm whale. There have been claims of specimens of up to 66 feet (20 meters), but none have been officially documented. Giant squid can grow to a tremendous size, offering an example of deep-sea gigantism: recent estimates put the average size of the giant squid at 33 feet (10 metres) for males, and 39 feet (12 metres) for females.

The dead squid's two tentacles were ripped from their base and large sucker marks covered the mantle. Evidence from statoliths (a small mineralized mass that helps squid balance), which accumulate "growth rings" and can be used to measure age, suggests that giant squid live no more than five years -- which means each squid must grow incredibly quickly to reach 30 feet in just a few years! Once that was done the specimens were wrapped carefully in cheesecloth and crated tightly for their trip. A giant squid attacks a boat - something that has not been known to happen in real life.
