Worms turn bright blue with fright

Marine parchment worms have an unusual response to threats. They release a sticky bioluminescent mucus that glows blue. This physiological response is unique because the bioluminescence is constant as opposed to appearing in flashes like other marine organisms. In order to produce sustained light, the mucus would have to contain a source of energy. What they found was that the slime contained an iron protein called ferritin.  When the team […]
