Rich a pu en apercevoir quelques-uns des plus étranges : les calamars, qui perçoivent les goûts avec leur peau ; les crevettes, dont le squelette, comme les langoustes, se situe à l’extérieur de leur corps et non à l’intérieur de celui-ci, comme c’est le cas pour nous.

The truth about these magnificent sea birds is even more amazing. Without even flapping once, an albatross can glide for hours and cover several hundred miles! No other creature can do this. The bird’s secret? It’s called dynamic soaring. They spend half their time gaining height by angling their wings while flying into the wind. They then turn back toward the sea, swooping along at speeds up to 67 miles per hour, till they catch another updraft skyward. And do it again and again, expending remarkably little energy. By studying exactly how they do it, engineers are trying to design more efficient airplanes.
