About this 3D model

On Earth, organisms including fish, reptiles, birds and mammals all share the same basic body plan - 4 limbs with 5 digits on each, a head with two eyes and a mouth, etc. If you started with a different body plan, and tried to explore permutations to occupy different ecological niches, what would you come up with? These creatures are a thought experiment, they are all descended from the [same 6 legged "ancestor" skeleton](http://www.123dapp.com/3dcr-Creature/Martian-Hexapod-Ancestor/1354687), made with [123D Creature](http://www.123dapp.com/creature). This came out of a brainstorming session about how to use 123D Creature in teaching evolutionary biology, taking advantage of the feature that lets you re-use a skeleton and then sculpt a different creature.
