The soft footfall that signals dinner
The soft footfall that signals dinner A German physicist has developed a computer model
that explains how scorpions can locate prey by listening to ripples
in the sand. Scorpions detect movement on sand with sensors in
their feet and feel the vibration most strongly in the direction of
the prey. This tells them where to turn to face their prey. It is
possible that a similar process tells spiders where prey is in
their webs. 3 APRIL 1999, P. 6
