Turns out not all snails find flipping themselves over quite so arduous a process...
It's a conch from the Strombidae family. You can see the well-developed eyes peering out at the end of those long stalks, much like the picture above.
Obviously this one has a significantly more devilish shell...

Another thing about these particular conches is the peculiar way they get around.
They don't glide along slowly like other snails. Instead, they lunge forward in distinct, heaving leaps. They do it using a modified operculum. A lot of snails don't have an operculum, but the ones that do have a round, flat one attached to their foot. They use it to seal the entrance to their shell.

Thankfully, there's nothing to suggest they ever use it to carve up prey. In fact, they're all herbivores and detritivores. Phew!
