I posted a picture of this creature in another thread but I thought it would bring it to some biologist's attention and ask some questions.
How did this thing evolve?
I don't understand how it's genes could "learn" from its ancestors that mimicking a completely different animal(a viper) would be a good defense.
Doesn't this break all the rules of evolution? Genetically its about as far from a snake as you can get so how did it even "know" there was such a thing as snakes and that they were feared?
