Hybrids are a touchy subject for many. Many people feel strongly against them and that is their call. I personally feel that they are amazing snakes and it opens up a whole world of unique beautiful animals. Just remember those that that are creating hybrids and being honest about the snakes backgrounds are doing it right and you should respect that even if you do not buy their hybrids.
Being that so many people are against hybrids and badmouth the creators, this has caused many people to create them and not honestly claim them as being hybrids. This is destroying the hobby and as such you may have a hybrid in your collection and not even know it.
Here are some of the not so commonly known hybrids
Ultramel Cornsnake
Creamsicle Cornsnake
albino Greybands
many varieties of white sided kingsnake
many of the albino splendida
and there are many others suspected as being hybrids but cannot be proven
