Giant squids are several times the weight of an adult human and also get that big over only a handful of years.

And I'm guessing they start up a bit smaller too.
Usual adult giant octopuses are similar (in weight) to 3 year old humans, so it's not really surprising they get that big over a 3-5 year lifespan.
