Nah they are amazing!
Also octopus doesn't come from Latin, so plural is octopuses or octopodes
*the more you know*

It's actually correct both ways. just most people don't like octopi, I don't like octopuses... soooo.. yeah. xD

And I would rather see a flying spider than an octopus in any environment. They scare the hell out of me.

I just meant it has no etymological basis. d:

>> then there was really no point in saying anything. xD tell me about cacti now.

Cacti is actually correct, it does come from Latin.

Why does coming from Latin determine whether or not the plural is correct?

Because many words that come from Latin still keep their Latin plural in English, plus the normal English plural (cactus, cacti/cactuses).
But words that come from Greek have a different plural, so the latin plural can't be applied to a greek word.

xD so are you saying it's okay to call a cactus in plural cactuses but it's not okay to say octopi?

Indeed. Cactus is both a Latin and English word.
Octopus never was a Latin word. d:
