How Fast Is Starfish?

Starfish use hundreds of hydraulic tube feet to crawl at about 15 cm per minute. Each tube foot acts as a tiny suction cup, gripping and releasing in coordinated sequence — surprisingly fast for something that looks practically motionless.

Starfish have no brain and no blood — they 'see' through eye spots at the tip of each arm and circulate seawater through their body for nutrients.
