Speculation On Extra Solar Biology I think this could be an interesting thing to talk about, what could alien life really be like? Of course nothing like the stupidity shown in movies and on TV. To get this thread going I've provided a link to an unfinished world building project. http://www.eponaproject.com/ Try to think of other forms that could evolve to where they create technology. There probably are bipeds out there but not humanoid bipeds, just like there are other bipeds on Earth. I propose this sentient creature. The Idatonian tri-squid has three tentacle arms that end in a "hand" of six fingers that are arranged radially. They are semiaquatic, having both gill and lung-like organs. They don't have bones but are able to walk on land like they have because they have a "skeleton" composed of erectile tissue. The advantage of this is they can both lift loads but can also fit through small holes like octopi. The four eyes are spherical compound and are on the ends of movable stalks; much like snails. They communicate via a combination of chromataphores, iridophores and rapid clicking noises. When underwater they can kill prey by blowing at high speed tori that contain poison ink. They have also evolved the ability to splice genes into organisms. They steal some cells from a lifeform they like the traits of, cut the genetic material with specialised enzymes and use a virus they are symbiotes with to inject the genes into new organisms. Plausible?
