Another day, another antarctic ecosystem. I've always found it strange that, on land, the tropics are where all the biodiversity is, but at sea it's always some of the darkest, coldest places that have all the crazy critters. If the Burgess Shale and other similar formations are any indication, it's been like this a helluva long time. I'm sure there's a reason for it, I just can't ever recall one.
