I know there is a word for these things but I really don't know what it is. These are basically oxymorons only different... Anyway, I need some things which are named for things that they aren't related to. Don't give me plain oxymorons it would be better if they were some sort of an animal.
For example:
A catfish isn't a cat.
A song bird isn't made of a song.
A seahorse isn't a horse.
Jumbo Shrimp aren't jumbo.
etc.

Thanks in advance.

Also I enjoy the ones people have posted. Anyone know the terminology for these types of words. I remember doing something like this in Biology class but I can't remember.

Funorb isn't really fun.

Lol
I think these would just be a special class of oxymorons.

Well it has something to do with our English language. Like if we go somewhere else in the world and translate "jellyfish" in another language they wouldn't understand what you are talking about. It is like a common word we make instead of using a national one like the scientific nomenclature.

I think that when they were named they were given appropriate nicknames for what they look like and how they behave.

Here's another good example of what I mean.

A group of lions is called a pride so a group of gay lions would be a "gay pride"

Microsoft (does not) Works.

Mac Book is not really a book (definitions of "Book" provided by thefreedictionary.com - 1. A set of written, printed, or blank pages fastened along one side and encased between protective covers.)

Mac Book Air doesn't have much to do with air

A dragonfly is not a dragon (I hope)
