Non bi-symmetric&quadrupedal animals usually make b-movies or enemies in horror genre. I am also interested in life forms in other quark/lepton/ muon sorts in the current universe if possible. I m a firm believer that non-natural, non-random life forms will dominate the space exploration including robots, augmented humans, bio-robo hybrids and Supra and sub swarms of those.
