It also has the advantage of providing a fantastic defence mechanism against your potential predators. It is in esscence, chemical warfare. Various forms of venom usually contain a vast array of different toxins which can inflict damage in many different way. How did venom evolve?

killer cockroach zombies and their wasp masters will take over the world!!!

i fucking hate wasps

I've been wanting to say this from first video, the bee workers have only one sting, once they use it they die. But the queen bee produces lots of offsprings and mates all day long, and its hormones is how the worker bees trace their way back home. Hormones, toxin, sperm, whatever you call it, is all the essence where the cells called stem cells are produced. A species must have stem cells where they produce the DNA from, for safety deposit purpose. A rabbit with 3 homes, keeps their money safe

If that wasp didn't make your skin crawl, then nothing will. That is the stuff of nightmares right there.

[vamshiinhell]

cockroaches don't have a brain, they have ventral nerve cords which does not have a specialized brain.

No just movement and sensation for the most part but it looks painfull.

You people are all so concerned for the cokroach. You do know that the cokroach isn't even aware it's being eaten right? The signals in it's brain have been shut down it doesn't feel a thing.
