Cephalopod: the squid, the octopus, or the cuttlefish. 

The Greek word, κεφαλή (kephale) means, head.  Combine this word with the Greek word for foot, ποδός (podos), and you’ve got a cephalopod. 

That’s right.  A cephalopod is a “head-footed” creature.  Or, perhaps a “foot- headed” creature.  Never mind.  Sounds better to call it a cephalopod.
