Slimy Propulsion

First the gecko.  Now the snail.

`A UC San Diego engineer has revealed a new mode of propulsion based on how water snails create ripples of slime to crawl upside down beneath the surface. […]

Some freshwater and marine snails crawl by “hanging” from the water surface while secreting a trail of mucus. The snail’s foot wrinkles into little rippling waves, which produces corresponding waves in the mucus layer that it secretes between the foot and the air. […]

Anette Hosoi of the Massachusetts Institute of Technology, has already imitated the adhesive/ lubricating propulsive method of land snails to drive a robotic device.
