Sorry - here is what I know RE: information that helps identify critters.

(1) How big is the critter?

6-9 inches long, 3-4 inches wide, 4-5 inches tall

(2) Where in the world is the critter?

Photographed at Sunset Waters house reef, Curacao, NA

(3) What sort of habitat (reef, wreck, sand, rubble etc) is the critter in?

House reef, sloping wall

(4) How deep is the critter?

Photographed at 35-55 fsw

(5) What time of day (or night) did you see the critter?

Night dive, 9 pm - 12 am

(6) Any observed behavior of the critter...

Moved away from divers, fell over ledge, fell 2-3 feet, righted itself and crawled toward covered area

(7) If the locals have a common name for the critter, what is it?

When described to locals they did not have any thoughts on what it is.

I would guess it's a big 'ol honking sea snail, be careful some are poisonous

Isn't some kind of Moon Snail?

Looks like a nice cowrie.

Shape's wrong for either a cowry or a moon snail and cowries don't have an extended foot like that. The angle's wrong but guessing from the spire & the coloration of the foot I'd say the Atlantic Partridge Tun, Tonna maculosa.

Yep... yep... I think Tun is correct. Prettiest foot I've seen on one... nice.
