The giant squid (Architeuthis dux) is a genus of deep-ocean dwelling squid. Giant squid can grow to a tremendous size: recent estimates put the maximum size at 12 metres (39 ft) or 13 metres (43 ft) for females and 10 metres (33 ft) for males from caudal fin to the tip of the two long tentacles.
Until 2005, nobody had ever seen a giant squid that was alive. Only dead giant squids had been found. On 30 September 2004, researchers from Japan took the first images of a live giant squid in its natural habitat. Several of the 556 photographs were released a year later. The same team successfully filmed a live adult giant squid for the first time on December 4, 2006.
History[change | change source]
For many years, people would hear stories from fishermen about giant squids at sea. According to the stories, an enormous squid would wrap its arms around a whale, causing a terrible fight to start. Whalers said that sometimes, when they caught a whale, it would have scars as big as dinner plates on its body. Other times, when they cut open the stomach of some of their whales, they would find squid arms as long as 30 ft with suckers up to four inches wide. The whalers who told these stories either chopped up the squid parts to eat or use as bait, or they threw them back out to sea before scientists were ever able to examine them. However, in 1861, a French ship was able to bring back parts of a giant squid so scientists could study them.
Then, in the late 18th century, several giant squids washed up on shore, proving that giant squids really exist. After that, many giant squids were found washed ashore or dead at sea. Scientists grew very interested in these mysterious creatures, but few ever saw them alive. Scientists think they spend most of their time in deep, cold ocean.
In December 2005, the Melbourne Aquarium in Australia got the intact body of a giant squid, preserved in a giant block of ice. It had been caught by fishermen off the coast of New Zealand's South Island that year.
The number of known giant squid specimens was close to 600 in 2004, and new ones are reported each year.
