Question	—	Hidden Aliens on Mars? How would you justify hidden aliens on Mars, which no one on Earth has discovered yet? I was thinking over it, and having them be primitive or highly advanced seems a necessity. The latter gives access to unknown stealth tech and advanced concealment methods, the former means we can't pick up their ... (more)	—	over 7 years ago
Question	—	Radiotrophic Deep Sea Life? Had a random thought. I was wondering if a uranium deposits underwater could result in radiotrophic plants or bacteria to sustain an ecosystem. One issue with this, is radiation has very short attenuation lengths in water. So it is questionable if the plants or creatures could remain the correct dis... (more)	—	over 7 years ago
Question	—	Alien Biological Temperature Control? I'll keep this one brief. I have an alien from a planet which has extremely cold nights and extremely hot days (the day and night cycle may be short or long, I haven't decided). When the alien gets too cold, it becomes comatose, and its heart beat slows right down, like a strangled alligator. When t... (more)	—	over 7 years ago
Question	—	Help me Explain this Alien's Traits I'm looking for biological explanations for some traits I want to give to an alien creature. Description of the Creature It looks like a five foot tall praying mantis, or perhaps a centaur. It has six limbs: Two big hind legs bent like a grasshopper's, along with two cat-like legs, on its lower bod... (more)	—	over 7 years ago
Question	—	Ancient Slingshots? Ancient (Vulcanized) Rubber? This, unsurprisingly, is also related to mermaids. Spearguns using rubber bands and the like are popular underwater weapons, so slingshots would be useful to mermaids. The problem is, these require(?) vulcanized rubber, which was invented in the 19th century. I'm wondering if there is any way you c... (more)	—	over 7 years ago
Question	—	Non-Enclosed Boat/Backless Boat? I was considering the possibility mermaids might make use of sailing ships similar to the USS Monitor, but with sails and supposedly wood. Now, the mermaids wouldn't mind the ship being filled with water, in fact they'd prefer it. Water is heavy: you don't want your ship filled with water. The air i... (more)	—	over 7 years ago
Question	—	Mermaid Buoyancy: Oily Livers, Swim Bladders and Lungs There was a good question and answer here: Does mermaid evolution come with buoyancy control? But I would like to expand the question. I got off talking with a friend, it got me thinking about mermaid buoyancy. It came up that perhaps mermaids should exhibit some synergy or combination of the method... (more)	—	over 7 years ago
Question	—	Mermaids on Land? One of the inspirations for this was Tactics Ogre: Knight of Lodis, where I liked their depiction of slithering, combat-worthy mermaids. I've been trying to develop mermaids who make pilgrimages to land cities, and have been considering mermaids with shore-side villages and towns. For this purpose, ... (more)	—	over 7 years ago
