Planet Dump25... Widely known as one of the worst planets in the galaxy, but not as bad as Dump26. The sickly glow of a diseased star irradiates this misbegotten place daily, providing a feeble facsimile of sunlight to the two and a half species of MISERABLE FUCK that live there.
the ELLY is a photosynthetic creature that uses its big veiny EARS to gather SUNLIGHT
the PHANT is a CARNIVORE, it EATS the ELLY
the BUTTLEECH is a FREELOADER, it SUCKS poop from the PHANT's butt
Perhaps in time, these genetic rejects will give rise to a thriving ecosystem... But probably not

Rules:
1. Find a creature suffering from environmental pressures
2. Copy it into MS Paint (or any other anti-aliased drawing program, if you're fancy like that)
3. Add a feature to the creature that will make it better at not dying
4. Reply to the post that had the old creature with your new, improved creature (and describe how it's different)
It's that easy! And they told me you needed a degree to be an evolutionary biologist...
