Octopuses. (the plural form of octopi is not correct)
That is the correct spelling of the plural of "octopus", which is "octopi".(not all -us words form the -i plural in English, e.g. fungi but hippopotamuses)
Octopuses or octopodes. The Anglicized (and most common) plural form of octopus is octopuses. Although it is often supposed that octopi is the 'correct' plural of octopus, and it has been in use for longer than the usual Anglicized plural octopuses, it in fact originates as an error. Octopus is not a simple Latin word of the second declension, but a Latinized form of the Greek word oktopous, and its 'correct' plural would logically be octopodes.
Please note that the plural of 'octopus' is not 'octopi'. It is 'octopuses', or if you want to be really pedantic, it's 'octopodes'.
