First and foremost, Circus of the Spineless is back! Get your invertebraty goodness at The Other 95%.
Secondly, at some point in the not-too-distant future, I will be composing a post with a line-up of the the most incredible organisms of all time. As part of my preparation for that post, I'd like to hear what your nominations for the title would be. They can be living or fossil, abundant or exotic, animal, plant or otherwise. I only have one little challenge to the question - I'd like individual species. If you think the most incredible organisms are, say, ants or asteroids*, then try to think about what specifically is the coolest ant or asteroid out there. If you could also tell me why your nomination(s) are so cool, that'd be great.
*I'm being deliberately vague about whether I'm referring to asteroids the animals, or asteroids the plants.
