A note on the plural: Fowler states that "the only acceptable plural in English is octopuses", and that octopi is misconceived and octopodes pedantic. That said, Merriam-Webster now accepts octopi as a plural form. Word formation based on misconception is a rather common occurrence ( See: pea, lase, ... ) The collective form octopus is also used, but is usually reserved for animals consumed for food.
