This is not the result of genetic cross animals with plants, but a good Photoshop! An excellent photomontage, one of the best in recent times, I recommend you to see it.
This is a case, when all is simple and divinely beautiful and the first who got how to do this was Robert. He put on a metal board different plants and passed through them the electrical surges of 80,000 volts. Immediately after that, he took pictures. You must see this, it is really very beautiful; it may seem that it was photoshopped but the pictures are real.
