What will an alien look like on Venus and why it will look like that?

Answer 1

A legless bird with no eyes or legs, that carries plants which cling on to its back that absorbs sunlight every 121.5 days.

Let us look at it logically. The alien will have to be comfortable at a temperature of 860 degrees and at 92 times the atmospheric pressure of Earth. It has to breathe something, it can't just survive off of heat and minerals. It would have to breathe CO2 right? It is the most abundant element in Venus's atmosphere, but if in doing so you wouldn't have a complex creature, and since the main geology of Venus is volcanic plains that were found in 2005 to be active. Your little carbon dioxide breather colony would probably be fossilized from super heated rock before it could even move. Okay what if the creature breathes nitrogen, the second most abundant element on Venus. That wouldn't work out well either. Even though ancestors to life were said to breathe nitrogen those were even simpler creatures than the plants we see today.

So does alien life live on Venus or is it just a trivial question with a fruitless answer? Well if you know your stuff you would know that in our atmosphere carbon dioxide sinks and can be contained in a beaker without a lid. This is because it is more massive than oxygen, and gravity will have more of an effect on it. So the same thing happens on Venus. Except all of the oxygen and hydrogen congregates to the top. Not only does this eliminate the CO2 problem but it also eliminates the problem of pressure, heat and light. We no longer need to make an albino lobster plant, that needs to survive the pressure of being 3000 ft below water. We can have some more elbow room. With less atmosphere we don't need to worry about pressure there is no more sulfuric acid clouds, and no blistering heat that evaporates those same sulfuric acid droplets before it hits the ground. Not only that but we also have Oxygen!

Up in the higher altitudes of Venus there is no land, which is no problem; the volcanic plains were just a big pain in the but anyways. This creature just needs to be just as massive as the air you breathe. Micro organisms, which could evolve into a type of flying ecosystem that will never need land. The first creature may be similar to that of a plant or even a hybrid plant-animal microscopic organism which are totally plausible. Some type of microscopic bug of sorts. Once they start evolving symbiotic relationships can occur everywhere. You'd probably see plants growing on the back of legless bugs or even creatures big enough to be fleshy. These bigger creatures would need to never stop flying though, similar to that of a dolphin, when it sleeps, but keeps moving. The Days and nights of Venus are very long. So eyes would only be a hindrance. Another way of detecting surrounding is echolocation, which can be used as a more useful alternative.

Our end product is a eyeless and legless beast that scours the air as a hunter, which carries plants on its back which stores up energy in the morning to use to live during the night.
