Prior to reading this, I'd have been tempted to correct anyone saying octopuses. Who of y'all says which?

This matter was the topic of an email I sent to Anu. In an AWAD email it gave octopi as a possible plural, but did not list octopodes One of my dictionaries lists octopi as "wrong", not as an acceptable option. I asked Anu why his bulletin did not list octopodes, but the query was deemed unworthy of a response. While I have more less settled on octopodes, your post got me wondering what a group of octopodes is called. Any ideas, anyone?
