'The standard pluralized form of "octopus" in the English language is "octopuses" although the Ancient Greek plural "octopodes", has also been used historically.'[1].
The book "Octopus: The Ocean's Intelligent Invertebrate"[2] which I have here says this on the matter: "By the way, the plural of octopus isn't octopi, because the word is Greek -- octopus to be exact -- not Latin. The Greek plural would be octopodes, but we call them octopuses."
You're not being pedantic as it pertains to this word in the English language, you're just wrong.
