What everyday problem could a body like a ferret solve?
Love all the wonderful ideas that pop up while you watch this video of a ferret in slow motion. Like magic the ferret lowers and stretches itself out, making its body 30% longer. This helps they when they are running through small tunnels.
Amazingly they loose almost no speed when travelling through small tunnels. There bodies are designed to switch the shape when they are running in tunnel.
Ferrets hunt in burrows that are tight and twisted. They bend their bodies up to 180 degrees, both vertically and horizontally.
