The TED party at the Monterey Bay Aquarium is my favorite because they scatter mattresses around in front of the major exhibits. It’s much easier to observe the creatures for a long time when you don’t have to stand, and thereby notice the patterns that repeat over longer time scales. One of my favorites is the slow dance cycle of the sea turtle across large distances in the shark tank.

Laying on the mattress, the anchovies overhead shimmered through resplendent patterns of emergent forms, with each fish lacking a global perspective, and following simple rules (e.g., , follow the fish nearby while using pressure signals to avoid neighbor collisions; roll back to the center if you find yourself on the dangerous periphery, faster if you see something dangerous ahead, like the shimmering blob of another school of anchovies that had split off and gone around the ring in the other direction…).

For some time, I have been wondering how the fish experience this…

  1. Lovely!

    Isn’t it rather how human beings react in a crowd? In life too? The followers are those who are just content to be part of the crowd but not feel too crowded, protective of their own selves, not too concerned with the reason for their actions as long as they get to where they think they should go and do not get hurt in the process.

  2. Well, more like swarm stupidity – I’ve seen the anchovies in the big kelp forest tank get themselves locked into a torus going round for ages until something big comes along to disrupt them.

  3. there ‘s warm’ Birthday Wishes swirling all around flickr for a special fish today … have a great one, hope it’s a rush!

  4. Very "swarmy"… with their glowing eyes. Looks like they’re avoiding a pizza.

  5. My favourite aspect of swarm intelligence is emergent phenomenon can evolve faster than the biological substrates of the individual. Organismal encoding is *so* Precambrian.

    I like my meaning between the lines. -or, for the Brits, Mind the Gap!

  6. That’s a cool observation, and a sweet way to set up a fish watching party! Did ja bring your to SLR dabble with too?

  7. nope – just the pocket camera…. and I did not try to use the waterproof one here…. 😉

    Rocketeer: they have that look… They also look like they are practicing a cram into the tin can.

    Todd: so true. When we pop up to a new layer of abstraction in evolution, it quickly subsumes the lower levels to become the dominant vector in a hierarchy of nested time scales. Or as Kurzweil puts it:
    “Each epoch continues the evolution of information through a paradigm shift to a further level of ‘indirection.’ (That is, evolution uses the results of one epoch to create the next.)… Most of the intelligence of our civilization will ultimately be nonbiological. By the end of this century, it will be trillions of trillions of times more powerful than human intelligence.”

    Happy Birthday
    fishes!!!

  9. This is the best display at the Aquarium, surpassed maybe by the jellyfish. But the sardine room is hypnotic.

  10. It would be interesting to have a pet game, like Nintendogs, but with swarms.

  11. Hi Steve, this is really great – and I love those ghostly jellyfish !

    I’ve chosen it for the competition of the week at Scientist Photographers group, you can follow the scoring in the discussion section of our group! Good Luck!

  12. A cool update in today’s EDGE:
    "We now know that these [predator evasion] maneuvers are created by the relatively local interactions among the individuals. But if you take an individual, say, a herring, from the school and isolate it, it will die of stress.

    It is a bit like taking cells from your body—when you take them outside the body, they are unable to function. Of course it is not as closely integrated as a body, it is not as closely integrated as an ant colony. But there is this high level of integration among unrelated individuals. And in terms of how the genes are going to propagate, genes that allow individuals to function collectively as a group are going to be extremely important. So one has to then begin to think about the level at which selection is actually functionally acting."

  13. Just saw a cool video of a huge aquarium in Japan…. You can kick back for a few minutes and enjoy the soothing flow…

  14. Thanks for posting my video jurvetson!

    I appreciate it!

  15. Thanks Mimosa for a pointer to a very cool video of a murmuration of starlings.

  16. Just saw an awesome short video of a fish swarm under shark attack (@Singularity University)
