    Then it got a face full of mud and died.

    That’s pretty cool, I guess, if you are into that sort of thing.

    The University of Victoria’s underwater robotic exploration team found a rice cooker full of octopus on the ocean floor.

    I’m pretty sure this is evidence supporting intelligent design;)

      I would love to test your theory by submitting an article on this lovely animal to Conservapedia and observing how many milliseconds it takes for it to be removed. But I only have enough spare time to read BB today…

      Hmm. Perhaps it supports the “designed” part, but certainly not “intelligent”. More supportive of the “absurd design,” “irrational design” or “silly design” theories.

    Thanks to TMBG, my kids are very familiar with the Tripod (and Triops).

    Looks like its 3D

    When we’ve overfished the other species into extinction, this fish will be renamed “deepwater tilapia” and be found on our plates. Most engaging will be the preparation where the tripod fins are left on, so you can stare at it eyeball to eyeball before taking a bite.

    I suspect that it’s about being very very quiet as much as saving energy. In a world that never sees the sun that could be very important

    Awesome. It’s like The Fastidious Fish from Tomfoolery was real all along!

    Chickens have two legs
    And firemen have two legs
    And monkeys have two legs
    But tripods have three legs

    A pity the HDD (presumably for the onboard still camera) was 99% full. If I was flying that ROV, I’d have been snapping away, getting some good stills (And before anyone says anything, yes, I _AM_ an ROV pilot)
    David, after reading the Wikipedia entry, and seeing how it feeds ( ) I’d imagine that it has something to do with the boundary layer effect. In areas of current, there’s often a zone extending a small distance from the bottom where there’s no current, called the boundary layer. I suppose it could be thought of as being like how it gets windier when you’re at altitude? I’d imagine that the pectoral fins/stilts evolved as an adaptation to get it up above the boundary layer where it can be exposed to more prey drifting by; if it waited right on the bottom, it could be waiting a long, long time.

    Some possible evolutionary advantages:

    Distance from parasites in the mud;

    Prevents silt cloud that may be caused by large surface settling to silt, or by movement once settled, thereby removing a warning to prey and a signal to predators;

    Removes ground effect (low pressure area under bodies that causes bodies during liftoff to have less lift than expected for locomotor output) thereby improving agility;

    Increased tactile area with distancing from hazards (ten-foot-pole effect), including water movement;

    May augment tip eddies from fins (increasing, decreasing, or re-vectoring) during movement, thereby augmenting pressure differential between opposite sides of the fin;

    May augment pressure wave wake to make fish seem larger or smaller to prey or predators that rely on sensory input from pressure wave sensing (“sonar cloaking”).

    Not an exhaustive list, but what comes off the top of my head.

    And the obvious “some prey never look up” effect.

    Transitional form? I vote ‘yes!’

    Pretty good match.

    ‘Tomfoolery’ was based on the works of Edward Lear. Here’s the Fizzgiggious Fish (not fastidious).

    Is that your caudal fin extension or are you just happy to see me?
