Spiders Save Energy By Living Upside Down
By Nick April 9, 2008
Researchers from Spain and Croatia studied more than 100 spider species and discovered that many of them travel upside down to save energy. For them, walking is the same as swinging, so their legs are more like claws fixed on their exoskeleton.
Spiders don’t need strong legs to stay and move upside down, so they act as a pendulum, using their body weight and gravity to their advantage. The longer their legs are, the greater the pendulum effect is. Long legs are not so useful when crossing floors or pullulating with the legs under their bodies.
The informations are important for the better understanding of spider morphology and evolution, but the scientists believe that these principles could also be applied in robotics design.
