Flatworms can move fast along the bottom by rapidly beating tiny hairs which act like millions of feet to propel them along in an undulating manner.
They feed by placing themselves over their victims and sucking in their prey, a tube like extension in its mouth acts as a grinder.
Many flatworms are confused with seaslugs and visa versa. Ref: x
