As some of you know I have been on the hunt for great ceph footage since I am fascinated by these creatures but will never own one. Anyway, I came across this gem today. The following link points to a video on PBS' site that shows what happened when an aquarium decided to put the octopus (I am pretty sure it is GPO) into a tank with sharks and other large predators. My jaw hit the floor when I saw this. http://video.pbs.org:8080/ramgen/wnet/nature/octopus/shark.rm?altplay=shark.rm Sorry if the video is old news but there are likely other members besides me who have not seen this.
