giant squids and gigantic octopus....first a look at squid
from http://www.newanimal.org/Sailors knew about the octupus and squid, real ocean animals that had tentacles. However, the kraken was considered to be a different species because it was much, much bigger. Sometimes it was thought to be a giant octopus, sometimes it was thought to be a giant squid.
During the early part of the scientific era, the kraken was considered just as likely to exist as sea serpents. In other words, it was laughed at. Serious scientists steered clear of the kraken question, refusing to study it even when presented with beached kraken carcasses.
Several kraken carcasses were beached within a short time of each other, and there was such an uproar that the reluctant scientists were forced to pay attention.
The kraken was declared a real species. It was named the giant squid. The giant squid remains one of the most elusive large animals in the world. For many years, scientists tried to observe the giant squid in its habitat, but failed. Many people claimed to have seen giant squids, but they were mostly fishermen and sailors, the same people who are not believed when they report sea serpents.
Every live sighting was unconfirmed and in each case the witness was not a scientist. Scientists spent millions of dollars on expeditions, but could not obtain video footage of a live squid. Everything that was known about giant squids was based on dead bodies. All expeditions into deep water in search of the natural habitat of giant squids had proved fruitless. The giant squid still had much in common with mythical creatures and true cryptids, even though the scientific community no longer had any doubt that giant squids exist.
In September of 2004, that finally changed. Japanese scientists attracted a giant squid with a baited line, and automatic cameras took more than 500 photographs of the giant squid before it ripped itself free, leaving an 18-foot length of tentacle still attached to the bait.
There is still doubt about just how big giant squids get. Both eyewitness sightings and sucker scars on sperm whales seem to indicate that there are squids much bigger than any dead body we currently have. Most scientists refuse to believe that squids that huge could exist. Is there more than one species of giant squid out there, with one of them being really, really huge? Are the giant squids that have been netted near the surface or that have washed up on beaches the smaller ones?
Skepticism towards the idea of truly huge squids has weakened recently. Now, scientists think that the Antarctic species of squid called Mesonychoteuthis hamiltoni actually grows much bigger than the giant squid. They don't have proof of this yet, as the only complete specimens of Mesonychoteuthis hamiltoni have been juveniles, but the size of these babies suggests that really big adults are out there. In recognition of this, Mesonychoteuthis hamiltoni has recently been given the common name of "colossal squid."
