Bobbit worms hunt by burrowing into the ocean floor and sticking their five striped antennae up above the sand to detect prey. Once a morsel swims by, the worm grabs it with its impressive, pincer-like pharynx. It then drags its catch down into its hole to be devoured. Bobbit worms have proven themselves more than troublesome for aquarists who unwittingly bring a baby one into their tanks. A four-foot bobbit worm once terrorized a Cornwall aquarium for months before workers finally discovered him living in the coral, removed him, and named him "Barry."
