Book Description

For over 250 million years, the "crocodile" in the sense of a form of life occupied the top of the food pyramid between water and land. However, this included many different species, most of which were not linearly descended from each other despite enormous similarity. Often, they were even only very distantly related in the huge family tree of reptiles. Now Steffen Pichler shows that this pronounced convergence must be grounded above all in a recurrent selective orientation towards one specific goal: namely, the broadest possible "ecological harmony". Based on years of observations of free saltwater crocodiles in northern Australia and the evaluation of palaeontological studies, he proves that this manifested seamlessly in every aspect of physique and behaviour. The heavy body can glide almost turbulence-free on mirror-smooth water surfaces. The all-day existence is so extremely unobtrusive and quiet that disturbances caused to other creatures are close to zero. The killing of prey is done in an utmost surprising way and mostly within seconds. In addition, there are many positive effects, such as those as "health police" through the automatic selection of diseased fish or even that of an indirect "protector" of the well-rehearsed ecosystem against disruptive intruders. The author explains that with real observation and a little "thinking around the corner", the ecological harmony of the crocodile becomes as obvious that there can be no stable counterarguments and that even the best engineer could not find any potential for an optimization. However, in the public alienated from nature, artificial factors like focused slow-motion films of the mostly tiny moments of killing prey form the dominant impression. This and some other distracting influences make not only the layman miss a chance to use the crocodile for very deep insights. Pichler shows how the reflection of the crocodile form reveals a whole structure of most fundamental natural laws, which were literally missed by the civilising sciences, although their exploration would have been of highest importance for mankind. And he takes the logical conclusion so far that it eventually even reaches beyond the boundaries of space and time.
