Saturday picture show: Eight bioluminescent sea creatures


Ctenophores, or comb jellies, are gelatinous organisms that cruise the oceans using the rows of cilia which line their bodies. They’re simple in design, and very beautiful to watch as the cilia produce shifting rainbows of color. We occasionally had these at the aquarium where I used to work, and everyone — staff, volunteers and visitors — found them mesmerizing.

For seven other sea creatures that make their own light, check out this slide show at Wired. (The photo of dinoflagellates lighting up a wave is gorgeous.)

    LOVE this! As a kid this stuff fascinated me. As an adult, apparently it still does. thanks.

    I find bioluminescent sea creatures not only beautiful but fascinating beyond belief. How incredible it is for a biological creature to make it’s own light.

    I would certainly fall into the group of mesmerized observers.

    Wow, so beautiful! I love polychaetes, and that vampire squid easily tops the list of Coolest Animal of the Year (So Far).
    Light-creating dinoflagelates are fun. At one of the research stations owned by Stockholm University, there’s a boathouse where the water is often full of them. We’d go in there at night and throw pebbles at them for entertainment… Impossible to photograph, though.
