Suction cup

A suction cup, also known as a sucker, is a device or object that uses the negative fluid pressure of air or water to adhere to nonporous surfaces, creating a partial vacuum.

Suction cups occur in nature on the bodies of some animals such as octopuses and squid, and have been reproduced artificially for numerous purposes.
