We all have our own way of understanding the reality, although that does not mean that it is representative. Let's think, for example in the nemátodos. “The this pesao is already”, you will say many “speaking about filthy bugs”, good since yes. The nemátodos come to story because, except due to not very agreeable certain illnesses, most of the human beings are lived by us completely foreign to his existence. There are not even nice worms, like the poliquetos, or moderately interesting or disgusting, like the leeches, simply there are a worm limited to his elementary form, blancuzo, insipidly, tiny and completely obviable.
About 25.000 nemátodos species are known. They can seem great, but in the context of the long million and a half species of organisms (in 70 %, insects) that know each other do not seem great, scarcely a modest 1.6 %. Well, since the nemátodos are throughout and establish all kinds of symbiotic, often very narrow relations with a few certain organisms, it is thought that with all probability the importance of the nemátodos has been undervalued very much, probably in one or more magnitude orders. In fact, some specialists in invertebrates suspect that the nemátodos in fact might have a diversity comparable or superior to that of the arthropods. If to this we add to him that, although we do not know how many species exist in the whole world, but the whole world seems in agreement in which we know only one small part, we would be speaking about million species of nemátodos swarming round there. The world is a gusanal.
Let's think now about the fungi. The same you believe that you know more of fungi that of nemátodos, but it is not necessary to exaggerate either. Of course when one speaks to you about fungi think about this:
And also you will be wrong. The "mushrooms" are only the visible reproductive body that they produce a species fistful to liberate the spores, but the hifas are the real "body" of the mushroom: a network of microscopic filaments that spend the life without sorrow or glory mainly in the soil. Namely that although some of them produce mushrooms, the mushroom basically is a set of bland hifas that walk round there perreando without we paying the most minimal attention to them.
Again speaking in numbers: it has described approximately 70.000 species of fungi (of some of them a few ADN sequences are known only obtained blindly). Although the estimations have ranged very much in the last years, it seems that very possibly they exist on one million and a half species of fungi, that is to say, so many species as that today it has described joining all the modern living beings. Again, a diversity inabarcable and anonymous, buried and in the dark or happening unnoticed for the humanity in an immense proportion.
This parallelism between the nemátodos and the fungi is not a coincidence. For the human being there are absolutely foreign creatures that do not say anything to us: they are small, scantly usable, underground, only we intergesticulate with a small proportion of his wealth, nothing representative and for our senses they are bored enormously and uniform … and nevertheless there can be one of the keystones of the biosphere. His world is absolutely different: without light and without sound, but with a wealth of chemical signs and of complex interactions that we do not prune ourselves not even to imagine.
Sharing so many things, it is no wonder that both lineages intergesticulate often. Perhaps the most surprising thing that happens that we know is that h moan fungi nematófagos, that is to say, fungi that they "eat" nemátodos.
The fungi nematófagos more acquaintances produce a few pitfalls with form of ring that close when the worm happens across him catching it and, possibly, digesting it thanks to a few special hifas that him suck to the worm up to the first mush.
Animation of the pitfall (constrictive version)
I have not found videos where is seen how the moment of the apprehension, but here we see a poor wretch nemátodo trying futilmente to escape of his mushroom captor.
These rings are the only one of six types of pitfalls that the fungi has developed during his evolution, including sticky hair of different forms, bonds, and real networks. According to this page there are known 160 species of fungi that they devour or parasitan to nemátodos. We know that there are a small part of a much major amount of to which our ignorance is encyclopedic. Extrapolating the information of the estimations we can calculate that, as minimum there are 4000 fungi species worms hunters, a number fifteen times higher than that of carnivorous mammals that exist.
Let's think finally about the images of documentary that we have of carnivorous mammals hunting: lions chasing to gazelles, wolves running behind fawns, the shift fox killing a partridge, the bear catching salmons in Alaska, and a length etc. Well, there is a universe at least fifteen times more diverse under our feet in that harmful fungi puts pitfalls to worms, chemical ambushes have a tendency, spectacular escapes and the life take place and the death they continue his course completely behind the back of us, that we are considered so important with our vertebrae, our eyes and our mortgages. And again, this is an only one smallest proportion of this parallel universe that vetoed to our comprehension, and all this in the dirt and the ground on that we tread. I do not know you but it comes to me very well to try to see the life like a worm. Curiously it does that it feels less important.
