But all I could see-- those beautiful tree-like extended tentacles were not extended. The flatworm is the animal that you see at the top that resembles a leaf.
to do with the scientific or philosophical account of consciousness or the nature of life. I was on Twitter too late, as always happens. He put up a video of the regeneration of plenaria, which are these flatworms that regenerate very quickly. So if you're interested in what a living organism is, its independence, its capacity to maintain itself, I would put it in a kind of poetic way, its dominion over material things. Plenaria, a perfect example, that's something that we study at St.
But there again, an interesting sort of wild shape and character going on. This is another flatworm , orange-rimmed flatworm . And this is another flatworm , the Pacific spotted flatworm .
This is another flatworm , orange-rimmed flatworm . And this is another flatworm , the Pacific spotted flatworm . They're very beautiful, very delicate.
But all I could see-- those beautiful tree-like extended tentacles were not extended. This is a leaf flatworm .
But all I could see-- those beautiful tree-like extended tentacles were not extended. It seems like this flatworm is eating the nudibranch.
But all I could see-- those beautiful tree-like extended tentacles were not extended. It's the largest flatworm in the world.
This is called a four-lined flatworm . I happen to love flatworms . It's one of my favorite kinds of animals, and this is one of them.
But all I could see-- those beautiful tree-like extended tentacles were not extended. Some of the other flatworms have these beautiful patterns, just stunning.
And I'll get to that a little bit more as I go on. This is called a four-lined flatworm . I happen to love flatworms .
But all I could see-- those beautiful tree-like extended tentacles were not extended. This is his hand holding this flatworm .
But all I could see-- those beautiful tree-like extended tentacles were not extended. He said this is a giant flatworm .
It's one of my favorite kinds of animals, and this is one of them. And what I've learned is that flatworms are very important evolutionarily because they were the first kind of animal that had bilateral symmetry and a central nervous system.
But all I could see-- those beautiful tree-like extended tentacles were not extended. So I'm really glad that these flatworms are not the size of double beds because we'd be in trouble, I think.
But all I could see-- those beautiful tree-like extended tentacles were not extended. And then you see, in the lower right, this flatworm engulfed the nudibranch and consumed it.
And it's not really going to spark a kitchen revolution in the near future, because this is nanotechnology. Here in Britain, it was described as two-headed flatworms stun scientists, boffins baffled.
audience member#1: Thanks. Albert: Mm-hmm. audience member #2: Hi. You talked about trying to understand people. There's this stupid flatworm called C. elegans where we know the complete circuit diagram; every cell and every neuron and yet people have not been able to build a complete simulator of this worm. So, I look at that and I say, "We're very far away from being able to predict individual
people." We can predict statistical things and that's quite different. Have you ever, I don't know if you've seen the book, "Human Behavior and the Principle of Least Effort", by Zipf in 1949 where he tried to predict mass behavior, but I look at this specific simulations and I say, "We can't even do a flatworm ." People have also tried to do the garden slug and again, they know the wiring diagram and they can't tell you what the slug will do.
But all I could see-- those beautiful tree-like extended tentacles were not extended. And they said, oh, well, that's exactly what you're seeing because flatworms are carnivores.
garden slug and again, they know the wiring diagram and they can't tell you what the slug will do. Albert: It's, it's a lovely question. Essentially, is that, I mean I think that your question has many, many -- raises many, many issues. The flatworm , C. elegans, is one of my favorites, essentially. I have published quite a number of papers on that. I know, I don't know if you know, that you can knock out a particular gene and then you would make it to make all,
