Cephalopod filter: Do squid and cuttlefish have a sense of direction? It's more perplexing than it might first sound...

I know this is weird but it's been bugging my SO (and, consequently, me) for a while..
Squid and cuttlefish *seem* equally comfortable moving with their tentacles to the rear and to the front. Their eyes seem to have around 180 degree vision. I presume that their tentacles are the end of their body which requires most concentration, so when they 'jet' with their tentacles trailing behind, do they feel that they are travelling backwards? For that matter, is a sense of direction simply a product of vertebrate symmetry? Do echinoderms have a sense of direction other than up/down?
