Honestly, I revere all forms of life. But to participate in this thread, I'll say the red ants. I saw a documentary about the never-ending battle between the black and red ants. The red are immune to the black ants' venom, but the black are not immune to the reds'. The black ones are bigger and can crush them with their mandibles (don't know if that's the right word). IIRC, the red ants are currently winning the war. 🙁
