The technology is a field that nowadays is present in our lives, but the true is that the nature already knows of these distinct processes to attain his aims.
A good example is the navigation by magnetic fields that realises the turtle Boba. The Turtle Boba lives giving gone back in circles in the Atlantic Ocean. Each one of these hard turns ten years, and visits the at all desdeñable distance of 15.000 kilometres but, How is possible that always realise the turns doing exactly the same route? The reason is not cleared entirely, but knows that it is able to detect the differences of the magnetic field of the earth. That is to say, they have a species of brújula advanced that it allows him remember thousands of locations, tracing of this form an evolutionary map that transmits of generation in generation.
Another similar case is the one of the salmonetes, that before dying visit thousands of kilometres until returning to his place of birth. Some butterflies also follow similar cycles, to the equal that the birds, that achieve to orient in the migrations thanks to the magnetic fields attracted by a small organ that have in the head and that is formed by glasses of magnetite.
Another interesting example of the natural technology is the capacity of some snakes like the boas, which have an organ between the eyes that allows them detect the heat, that is to say, the infrared radiation of other animals. This allows them calculate with big effectiveness the position and distance of the prey even in the darkness. This sensor allows them the detection even if the difference of temperature between the animal and the surroundings in which it finds differs of so only 0,2 degrees centígrados.
Another similar case is the one of the Camarón Mantis, that issues a series of impulses of light polarised that so only can be seen by the animals of his same species. Of this form can communicate of silent way. To do us to an idea, we so only can distinguish some 10.000 colours, whereas the camarón surpasses the 110.000, including the fields of infrared and ultraviolet.
The shark neither remains out of the technology of the nature. By many is known the myth that the sharks can smell the blood to kilometres. The true is that this is not like this, but yes have of some small pores in the head that are fillings of an aspic ultrasensible to the electricity; the blood generates electrolitos, by what both joined allow him a capacity of incredible detection.
These and other a lot of curiosities of animal technology allow the evolution of determinate species, without which could be already extinct.
