A giant squid weighing 250 pounds and measuring 25 feet in length is prepared for exhibition at the American Museum of Natural History in this undated photo. The squid, which was netted off the coast of New Zealand in 1997, goes on display on October 12. PM/TBIt’s almost creepy watching this video of a colossal squid slowly thawing out in a giant tub at the Museum of New Zealand. If this were a horror movie, after all, it would suddenly start flailing around with its monstrous tentacles.

Researchers say that the squid, weighing 495 kg (1,090 lb) and caught off Antarctica in 2007, will be unfolded for study on Wednesday after it is defrosted. It is expected to be 6-8 metres long.

That could tell scientists more about colossal squid, rare creatures that are the world’s biggest invertebrates. Sometimes someone wanders into the video frame and you get a sense of how enormous the squid is.

So the video above is not just a curiosity that looks like a poorly stocked fish section in a supermarket with a broken freezer full of water. Japanese researcher Dr Tsunemi Kubodera shows on his laptop picture taken for the first time of a giant squid, the eight-metre (26-foot) Architeuthis, at the National Science Museum in Tokyo September 28, 2005. The images, taken in the deep sea at 900 meters (about 3,000 ft) off Japan’s Ogasawara islands September 30, 2004, are appearing in the journal Proceedings B of the Royal Society this week.

“This squid is a really nasty agressive sort of squid…a gelatinous blob with seriously evil arms on it,” the New Zealand Press Association quoted Steve O’Shea, a squid expert at the University of Auckland, as saying of a previous colossal squid in 2003.
