There are some beautiful jellyfish in San Blas that look like something from Star Trek at night. They are luminous but, rather than just flashing on and then fading, the luminosity is animated. First a bright light circles once or twice around the "nacelle" and then it streams down the tentacles before fading away. You have to wonder what kind of evolutionary advantage led to the jellyfish developing that ability.
