Is The Giant Squid Related To The Octopus?

Because of its long, snakelike arms, many think that the giant squid is some kind of octopus. But not so. There are many differences. The octopus has a round, baggy body with eight tentacles. The largest may weigh fifty pounds and have an arm spread of about ten feet.
Now picture the giant squid. It is ten times the size of the largest octopus. Its cylindrical body is about fifteen feet long, with, not just eight, but ten of the most awesome arms imaginable. Eight of these arms can reach out as much as twelve feet. In addition it has two tentacles with sucker-studded tips that can stretch out forty to fifty feet!
The arms also have rows of sucker disks raised on short, flexible stalks that allow the suckers to swivel in any direction. And, depending on the species, these suckers may have sharp teeth around their rims or claws that can be sheathed or extended at will.
