You probably didn't know that, but I'm a long-term fan of speculative biology (even before "The Future Is Wild" was released), but I have never taken a part actively.
Things have changed, and some time after I stopped with origami, I decided to start my own xenobiology project. I am still quite early on in the project and I'm aiming to create a global biosphere of an alien planet.
This here is a squid-like animal that lives in the seas of the planet. It moves by flapping with its four fins - when the upper fins go down, the lower fins go up and vice versa - and also by pumping water through the gill chamber on top of the body.
The mouthparts consist of four "C-.like" toothed blades arranged in two concentric pairs.
The jaws open to the sides, rather than up and down, and are suspended within the "lip" musculature, with only the teeth showing.
If you would like to see more of this, let me know, and I will upload more here, or follow this link and visit me on deviantart!
I created this critter in Sculptris.
I used a custom "material" created by nicksketch.deviantart.com/
