When we went to the Monterey Bay aquarium last weekend there was one awesome permanent exhibit with a lot of jellyfish. Also a "The Art of Jellies" exhibit which was pretty gimmicky if you ask me, though it did position a tank of jellyfish in a mirrored room, giving you the impression that they had you surrounded. But apparently the marine biology cartel now wants you to say "jellies" (or, I suppose "sea jellies") instead of "jellyfish", because those things are amazingly not fish.
The only other non-fish with a fishy name I can think of is "cuttlefish". I've never heard anyone saying you should call a cuttlefish something else, but I checked "on the line", as the kids say, and "cuttle" is the hot new name for that beast. How long has this been going on? Did people used to refer to cucumberfish, anenomefish, and urchinfish until someone rewrote the aquarium displays to encourage the biologically correct usage?
In an interesting reverse of this trend, at the aquarium I also noticed that the fish that used to be called a "dolphin" is now called a "dolphinfish". I think chopping "fish" off the names of obvious non-fish is not really worth it, but I'm glad about the "dolphinfish" change because that was really confusing. I'd hear about sport fishermen catching a bazillion dolphin and wonder why nobody was upset about that.

In high school or college I learned from one or another pedant that you're not supposed to call starfish "starfish"; you're supposed to call them sea stars because they're not fish. Well, they're not stars eithGAH MY EYES! Okay, some of them are stars. Also at some point I learned that octopods used to be called "devilfish". They're not fish either.
