Maggie Koerth-Baker flags a gorgeous but gruesome piece of nature footage:
From the "Cute Animals Devouring Other Cute Animals" file, I bring you this BBC video showing a mob of starfish ravaging the carcass of a seal pup. [...] The video speeds things up with time-lapse photography, which only adds to the alien creepiness as you watch thousands of starfish (plus sea urchins and giant meat-eating worms) damn-near gallop across the ocean floor. How do starfish eat a seal? Glad you asked. Turns out, they latch onto the seal's side, pop their stomachs out through their mouths, dump digestive juices onto the seal flesh and then slurp up the dissolved "soup".
