Goldfish Smarter Than Dolphins
flergum writes "While dolphins may have big brains, laboratory rats and goldfish can outwit them. It appears that the large brains are a function of their environment rather than intelligence. From the article: 'Dolphins have a superabundance of glia and very few neurons... The dolphin's brain is not made for information processing it is designed to counter the thermal challenges of being a mammal in water.' I guess this means that the Navy will start recruiting and training goldfish for those mine search and destroy missions."
...but don't goldfish only have a 3 second memory?
Forget thrust, drag, lift and weight. Airplanes fly because of money.
And thank us for all the fish? Surely goldfish don't eat themselves.
I doubt it. I think this is just exactly what the dolphins want us to think. Perhaps they are hoping that we'll leave them alone if we think they're all idiots and they can get back to the heavy schedule of light swimming and intricate whistling they had planned.
.. er.... wait.. a dolphin just called me and asked how long I could hold my breath. I think this worries me...
Well I'm on to you, dolphins! I'm putting the word out! I know you're smarter than goldfish and

Truly an astounding display of cognition.
So long, and thanks for all the flakes

So as you can see, Douglas Adams was right all along!Quantum mechanics: the dreams that stuff is made of.
"You put an animal in a box, even a lab rat or gerbil, and the first thing it wants to do is climb out of it. If you don't put a lid on top of the bowl a goldfish it will eventually jump out to enlarge the environment it is living in," he said. "But a dolphin will never do that. In the marine parks, the dividers to keep the dolphins apart are only a foot or two above the water between the different pools," he said. Manger says the thought to jump over would simply not cross their unsophisticated minds.
So because the dolphin isn't brainless enough to jump out of its tank and beach itself and die in the process, that makes them stupid? I suppose by comparison the child that plays away from road isn't as smart as the kid that plays in traffic, you know, the one that's seeking to "enlarge his environment" by becoming road pizza.
I am reminded of the counter argument which noted that the enlarged part observed in Einstein's brain was due to the extra glia cells needed to support the higher activity of the same number of neurons.
I've also dived with many varieties of fish, but our interaction with dolphins off Tiputa Pass and Trousers Point (you can find both easily on Google) was qualitatively different from any with fish.
It basically sounds like Japanese propaganda to me. Might be time to make that donation to Sea Shepherd.

I'm not anything close to the people who think dolphins are really really intelligent (though Douglas Adams makes a pretty good case), but IRTFA and I can not see how this is a serious article.
It ends: "Manger also points to the tuna industry, which under consumer pressure has gone to great lengths to prevent dolphins from being caught and killed by accident in nets.
"If they were really intelligent, they would just jump over the net because it doesn't come out of the water," he said."
Umm, yea, they would if they ware smart? *sigh* - how did this make *any* news at all. Even assuming that the gist of the article is true (about the different types of brain material) the rest is crap - was it "peer reviewed" (as the article points out) by other idiots? Maybe it is all a Rovian plot to discredit Aljazeera.net? I can not take the article and it's contents with any real sense of belief - it is so idiotic that I can not trust the rest of it. That's not to say they are incorrect - just that this individual article is is pure crap and one should not use it to base any belief on.

A fly has pretty much a hard-wired brain, but it is highly effective at finding food and keeping it alive.
Some while ago, some researchers managed to get a dish of 1500 (or 15000??) rat brain cells to fly a 747 simulator -- including handling complex actions like landing with wind shear. I bet it took less time to train the rat brain than it takes for a human to attend flight school. I guess a rat brain in a pilot's uniform doesn't pick up as much skirt though.

I'd take an octopus any day of the week! Not only are they excellent problem solvers, they give good massages.
You can count the number of neurons vs glia all day long, but at the end of the day dolphins seem to have MUCH better results than goldfish. Just because a certain feature normally has a certain result doesn't mean you can rewrite reality when it doesn't!
If the word "intelligence" was defined as a certain ratio of neurons to glia, he'd have a point. Of course, "intelligence" wouldn't matter so much, because it would only matter in certain situations. Much like "clock speed".
I also don't see how the "jumping out of the bowl/over the net" even deserves a mention...unless we now have a way of interviewing dolphins and goldfish.
Nature (evolution) tends to take the most efficient solution -- natural selection will favour the animals that don't need to expend so much energy to achieve the same result.
While it is obvious and quite dated knowledge that the sheer size of a brain is no indicator for "intelligence" (let us avoid the discussion what intelligence is in the first place for the moment), it is provably wrong that dolphins just do what they are "conditioned" to do. There have been many experiments that show that dolphins are capable to do a lot more than just demonstrate conditioned reflexes, including understand a several-word sign language and coming up with what could be called creative solutions.
Nothing of that sort has been demonstrated for goldfish yet, but that does not mean it cannot be done, just that we simply do not know yet.
It has been shown for other species that they show surprisingly intelligent behaviour when trained and it is probably impossible to defined what "more intelligent" should mean for non-humans (it is already quite arbitrarily defined for humans). So the bottom line is - more animals are more intelligent than most people think. And dolphins have shown a quite surprising range of abilities that was not observed in any other marine animal yet.

1. Dolphins have a cognitive sense of self, as shown in their ability to recognize that they are seeing themselves in mirrors. This is an ability only found in dolphins and higher primates (including humans). This is related to their extremely complex social structures, which implies high intelligence. And this is just one area in which dolphins seem to show high intelligence.
2. Glia are no longer considered 'noncomputational' by neuroscientists. Recent research seems to show that glia, and not just neurons, may perform computational tasks. This is highly controversial at present, but we are far from being able to say that just because an animal has lots of glia that that does not indicate a potential for high brain functions.

eTrade SUCKS
Dolphins get trapped in nets because they can't detect them, not because they're too stupid to know what to do. Aside from the obvious fact, as someone else has already pointed out, that a goldfish that jumps out of it's bowl and dies isn't nessearily very smart, there are could also be complex psychological factors at play as to why dolphins might not attempt to escape.
Dolphins are one of the few creatures that play games, such as playing tag with a peice of seaweed, or blowing bubble rings. This type of behaviour is often an indicator of high intelligence. To say that a Dolphin isn't much smarter than a Goldfish is an insult to both Dolphins and any human with half a brain to realise this article is a crock.
I disagree that jumping out of ones environment is a smart move, especially if you don't know what's on the other side. I disagree that dolphins are dumb because they get caught in nets because: a) how do you jump over a net if you find your self in the absolute center? b) maybe most do 'just jump over' and the ones caught are the dumb few. c) if a dolphin doesn't jump over a net it will become sushi, a dolphin probably doesn't know that it should jump over a net unless it knows it's dangerous, if a dolphin knows the net is dangerous - it's probably already been caught (see sushi statement). d) nets (i think) are designed to be fairly invisible, dolphins aren't known for having excellent eyesight and I don't know if their echo location is good enough to spot a net... Let's have a fish off and stick a dolphin and a goldfish in a tank and see who wins... actually to make it fair lets stick quite a few goldfish in there...
Clearly it was a slow news weekend. This report got a ton of coverage, which seems unwarranted given some of the abitrary standards of "intelligence" put forward by the researchers. The Wikipedia article on dolphin intelligence provides a far better balanced view of the subject.
I had a quick look at the University of the Witwatersrand website. Dr. Manger is a lecturer at the School of Anatomical Sciences. He is not an animal behaviorologist.
While Dr. Manger is no doubt qualified to discuss the structure of a dolphin's brain, he is in no better qualified to draw conclusions about dolphin intelligence than any of us here on Slashdot. Perhaps this explains some of his eccentric statements, or why his opinions contrast so sharply with other research indicating a high level of social complexity in dolphin behavior.
That Dr. Manger's study is "peer-reviewed" is really neither here or nor there, since peer review usually occurs within an author's specialty and Manger's most controversial findings transcend his field.
Dr. Manger's comment that dolphins should be smart enough to jump out of tuna nets would seem simply bizzare if they weren't so outright callous.
This is my post. There are many others like it. If you don't like what you read here, go try one of the others.
Glial cells apparently aren't really just placeholders and heaters. Scientific American ran a really good article a while back called "Did Scientists Miss Half the Brain?". (There is what appears to be a summary at this location.) It details a modern understanding of brain structure, which has overturned the former conception of glial cells as "just" structural elements supporting neurons. It would seem that glial cells can both sense and emit neurotransmitters, and those neurotransmitters can affect the operation of neurons. So linked to the electrochemical network we usually think of as the brain is another purely chemical one as well.
Also, even in humans, there is a "superabundance" of glial cells, in that there are approximately 10 glial cells for every neuron.
The Mongrel Dogs Who Teach
What is really disturbing about this story is not how wrong it is, but how it spread like wildfire through the echo chamber that is the web pages of the "respectable" news media. There seems to be zero interest in vetting stories anymore. Anything that sounds like a sensation and be linked to some other news page somewhere, is worth publishing, without a critical word added.
Back on topic, did you know that as far as we know, only three animals understand the concept of 'pointing at something'? These three are humans, chimpanzees and dolphins. Try it with your cat or dog. It will continue to look at your hand, not where you want it look, until the cows come home. Understanding symbols that stand for vectors in space require a greal deal of abstract thinking.

They have shown that dolphins have pattern recognition, the ability to learn and to anticipate the next part of a sequence. Dolphins have a language in which they commnicate with others of thier species. They have complex social structures. They can solve puzzles, they can be trained to do complex tasks.
I'm not saying that they're as smart as me, but they are at least as smart as other higher order animals, and certainly smarter than my goldfish who keeps trying to commit suicide.

Just to add on. I remember watching this in the Discovery Channel. Most people assumed that the dolphins are intelligent and friendly such that when boats sail in the ocean, they swim alongside the boat or even in front of the boat just to mingle with their human friends. However, this was not the *real* reason. Apparently, they noticed that there are a bunch of smaller, baby dolphins swimming in the opposite direction away from the boat, while those that mingle with the humans are the adult dolphins. This can be seen that the adults are distracting the humans while their youngs can swim off to a safer place. Such altruistic behaviour is hard to find in the aquatic world.
w00t
Carp (eg goldfish) live in an environment in which jumping from one body of water to another offers a real chance of accessing a new environment, e.g. a new pond or stream. It also offers the ONLY chance of survival for carp trapped in small, evaporating puddles of water, which may well be how goldfish register their surroundings.
By contrast, a dolphin has only a fairly low chance of being able to jump into a whole new ocean. A zero chance, in fact.
Therefore, the tendency to jump may be more a reflection of the chance that jumping will do a given creature any good, rather than a sign of intelligence.
Whence? Hence. Whither? Thither.
You may as well post an article about how scientists have discovered life on the moon and use the Weekly World News as a source.
CNN and FOX News are any better?
Come on. ALL major news sources are propaganda outlets. That's how it works. The problem only arises when people think that their own country's news agency are above corruption.
As for the article, I'm sure the guy interviewed really believes his studies. How does that reflect on Aljazeera? All they're doing is reporting on recent claims from academia. All newspapers report stupid science news. So what?

"Lesser women" is a contradiction in terms in this context: I'm a man.
I can only take credit for being willing to stick with Andy after his stroke. It's a long and ugly story, but following an argument with his custodial parent several years ago, they won't let me see him. To avoid making the story even longer and uglier and dragging the rest of the family into it, I've chosen not to fight it. The "up" side of his memory loss is that he doesn't realize that I haven't been 'round to see him in a long time.
