Well, this may be a little hard to explain. Almost every creature on the Sporepedia is easily identifiable into a certain Taxon category. Let me give you some examples:
Xeron here looks like an insect-'bug like',
while the Novaraptor is an avian-'bird like'.
What I want you to do is create something which simply looks like nothing on Earth. When you look at it, the thought 'It looks kinda reptilian' or 'it looks kinda mammalian' should not pop into your head. Oh, and if you people want some motivation, lets say a prize, then I will give you people a prize. By the end of every other week, whoever has created the coolest taxon will get a reward. I will subscribe to one Sporecast of your choice, getting you closer to the Rising Star acheivment.
-If I say it looks like a cetain taxonomy, it might not get accepted. But, if others back you up, saying that it is unique.
-You can create a taxon that someone else has already done. If you can't think of anything, this might be something you want to do.
-Please include the name of your taxon. Going to www.wiktionary.com and searching words which describe your taxon, then looking at translated versions of these words oftentimes makes a good name.
