The Australian research vessel, Aurora Australis, has been spending the summer conducting a census of marine life in the Antarctic. According to this Guardian report they have discovered some amazing creatures, including a jellyfish with 6-meter-long tentacles (over 18 feet, for metrically-challenged Americans). The mission’s web site contains a lot more photos. The video of the sea floor at 800m is particularly startling – it is like a garden down there.
