Bobbit Worms are a very strange nocturnal predatory worm. They have most of their bodies buried in the sand, with just their frightening looking pincers showing.  I was patiently filming a couple that were close together and my waiting paid off...  ..the first Bobbit Worm attacks and eats a foolish Scorpionfish that wandered in too close...  ...the second went for a Long Arm Octopus that got too close....I was quite upset, as I Love octopuses, but luckily the plucky little octopus was too tough for the bobbit Worm and escaped after a few seconds..
