Yes the largest one was 59 feet long and weighed a ton.
The body plan of a giant Pacific octopus typically includes eight long arms with suction cups, a bulbous head containing large eyes and a beak-like mouth, and a soft, flexible body. They also have a highly developed brain, complex nervous system, and the ability to regrow lost limbs.
All depending on the species you have. Most octopuses only live to be 2 years old. But the Pacific Octopus can live up to a max of 5 years, more than many.

big.
There are many different species of octopus - the smallest is the Octopus Wolfi, which is found in the Indo-Pacific Ocean. It is 1.5 centimeters in length. The largest is the Pacific Giant Octopus which can weigh 150 pounds and stretch 30 feet across in only two years
They have short term and long term memory. Allowing them to solve problems, puzzles, etc, and letting them repeat it. They are highly intelligent and have a very large brain capacity. The giant Pacific octopuses live longer and are known to be smarter.
It depends on the species. The Giant Pacific Octopus can indeed live for five years but others live only about six months. Octopuses only reproduce once. Males die no more than a few months after mating. The female dies once the eggs she's been guarding hatch. Although they stop eating after mating it is an endocrine secretion from the optic gland that kills them.
*Octopuses* have a relatively short life span, and some species live for as little as six months. Larger species, such as the North Pacific Giant Octopus, may live for up to five years under suitable circumstances. However, reproduction is a cause of death: males can only live for a few months after mating, and females die shortly after their eggs hatch, for they neglect to eat during the (roughly) one month period spent taking care of their unhatched eggs. [Octopuses are highly intelligent,*** probably more intelligent than any other order of invertebrates. The exact extent of their intelligence and learning capability is much debated among biologists
He will live for about 3 years.
Octopus' live about 3-5 years, so you can decide if it lives a long life or a short one. : )
Most octupuses fall in the range of 30 to 80 lbs weight. They are typically about the size of a small dog or a cat, with long arms. The largest octopus ever caught weighed 600 lbs, and was a Pacific Giant Octopus. Most octopuses are fairly small animals.
