Suction cup

A suction cup, also sometimes known as a sucker, is an object that uses negative fluid pressure of air or water to adhere to nonporous surfaces and in the process creates a partial vacuum. They exist both as artificially created devices, and as anatomical traits of some animals such as octopuses and squid.
