It's not your imagination: some of the same morphs are called different things by different breeders.And then there's the totally new ones...
Me, I pay little attention to morphs as I'm not a beeper-keeper at all (though I've had about 10 in the past), so I can't really help you with that.
If you haven't found it yet, it's "fun" to look thru Morph Market (& as others here can attest, it also leads to drooling & yelling "charge!").
