In fact this documentary is part of a more complete series:

Unfortunately the other episodes are no longer available on Arte + 7 but there are already extracts and summaries:
The art of moving and building efficiently should be of particular interest to econologists:

The movements and modes of progression of many species can change transport techniques. Bird watching thus makes it possible to design new types of aircraft; thanks to the spiders, one can imagine vehicles moving without hindrance on the sand; with lizards, the field of amphibious robots is concerned; as for water bugs or trout, they make you think about the principles of hydrodynamics.
In architecture and building, biomimicry is also on the rise. Janine Benyus was inspired by nature to design her house in Montana, heated by geothermal energy. Much further south, his colleagues are studying a Saharan plant that would improve cooling techniques.
While for other scientists, bamboo is an ideal model of skyscrapers, because of its adaptability to the wind. Some, finally, swear by dragonfly wings to solve ventilation problems or by corals to filter polluted air.
I have understood for a while (but not at school) that nature does "things" (builds, moves ...) according to the principle of minimum energy ... there is no mess in nature!
