Zero Gravity Life - Part 2
One of the most interesting environments ever proposed is an open atmosphere with no gravity, such as appeared in Niven's The Integral Trees and the wonderful Airspheres of Ian M. Banks Culture universe. Having painted flying creatures for such a world in this work, I thought I would take another crack.
Here is a sketch of the external features of a small [50 to 100 cm] quadrilaterally symmetrical life form. A social creature, it travels in flocks across the vast web like tangles of forest that drift in the air currents. It hunts for small creatures that live within the tangled stems, dipping its long snout into the leaves to nip out morsels.
Quadrilateral symmetry gives 360 degree vision, vital in a world where predators can attack from any direction or orientation. Motion is achieved by undulating four equidistant fins in the manner of a trigger fish or cuttlefish, and with four control axis, they are quite nimble as they dip and dive for food. Four jaws and a mouth like a sea urchin support slicing teeth that grasp prey like a set of needle nose pliers and shred it to smaller pieces to swallow. The paired orifices behind the eyes are for respiration .
From this sketch I will develop some kind of basic skeleton for the muscles to be bound to, and the internal organs.
Criticisms welcome.

Very nice Alex! Nice to have you back! As this would be a nimble and fast moving predator capable of quick changes of direction, I wondered what mechanisms its prey would have evolved? I'm reminded of the moths that have learned to simply drop out of the air when approached by bats - they've learned to sense the bat's echolocation. But the big question is ... Whatever happened to Zero Gravity Life Part 1?!
Zero gravity life part one was these fellas: http://www.alexries.com/Gallerypages/gal-fly.htm
Aha. Gorgeous work. My favourite pic.
Fantastic illustration!
Nice.
The points on the leading edges of the fins— are they for clamping on to things?
I'm trying to figure out why it would have so many "nostrils". I suppose each of the "quarters" might have 2 lungs-- one for each "nostril." But that seems excessive.
I wonder, how does this atmo/no gravity work? I'm a big fan of Larry Nivens, but I don't recall any book with that kind of "planet" in it. How would the atmo be help together if there is no gravity?! lol
Looks like we read the same SF. Love your work and ideas.
oh my god... it looks like an Elder Thing! I think you just figured out how Elder Things evolved! All they'd need to do is orient themselves vertically when entering an atmosphere.
One thing i'm not clear on though: How is it possible to live on a planet but not with gravity? Do you mean low gravity? Everything creates its own gravity, and with or without an atmosphere, a planet is going to be bigger than the things living on it. Hence, they fall towards it.
Any more coming?
Always a pleasure to find another Niven fan. Have you read the Legacy of Heorot books? I think you'd get a kick out of the ecology they've developed.

Your blog keeps getting better and better! Your older articles are not as good as newer ones you have a lot more creativity and originality now keep it up!
I am the sort of hombre who loves to taste hot things. Right now I'm making my private solar panels. I'm managing it all by myself without the assistance of my men. I am using the net as the only path to acheive this. I discovered a really amazing site which explains how to contruct photovoltaic panels and so on. The place explains all the steps required to building solar panels.
I am not sure bout how correct the info given there iz. If some experts over here who had experience with these works can have a peak and give your feedback in the site it will be grand and I'd extremely treasure it, because I really enjoy [URL=http://solar-panel-construction.com]solar panel construction[/URL].
Thanks for reading this. U people rock.

Im impressed. I dont think Ive met anyone who knows as much about this subject as you do. Youre truly well informed and very intelligent. You wrote something that people could understand and made the subject intriguing for everyone. Really, great blog youve got here.
The only question I'd have is, how does a creature like this breathe? If it breathes oxygen, it wouldn't have normal lungs to actually breathe I don't think, it can't breathe in a pressureless environment, unless it regulates it's own internal pressure. Also, if it doesn't breathe oxygen, what other chemical delivery system would allow it to generate energy to move and feed? Maybe I'm thinking too deeply, haha, but I also thought that IF it even breathes, it could use that momentum during exhalation as a means of propulsion as well, much like a squid uses the water passing through itself to jet through the water. Wow, I went all kinds of in depth, haha.
To Liquid: Air in microgravity still has it's air pressure otherwise astronauts could breath aboard the ISS.
