The design of anything is -adequate- for the environment.
Hardly perfect!
Their eyes have been said to be far superior to the human eye, for instance.
Yet have it and we don't.
Nature doesn't strive toward perfection in anything, just a "design" that can cope with the current environment.
When that changes beyond the capability of the organism to adapt, the organism goes extinct.
Apparently the environment for the octopus, if if challenges the animal, doesn't do it too rapidly for it to cope.
Other factors come into consideration too. If a type of organism is spread widely across the globe this increases its chances of having at least some species survive a severe extinction event. If the type of organism has less of an energy requirement it is more likely to survive. Crocodilians meet both of these criteria: They are fairly well distributed and they have a slow metabolism allowing them to survive long periods without eating.
