Slug noses

Thanks to MatC for suggesting this as a separate GI question.

The 'slugs have four noses' factoid has always really annoyed me and I think we should attempt to nail it.

As far as I can work out, slugs have four tentacles in two pairs. The top (longer pair) are used for seeing, and the lower (stubbier) two for smelling and tasting.

Are these noses? What counts as a 'nose'?

Maybe worth a PICTURE RESEARCHER checking it out and seeing if we can afford it.

I can get a good slug picture for you. Knockdown price.

*gets out nice fat macro lens*

I think 'nose' is just the name for the olfactory organ that appears on mammals, so it doesn't really work for slugs. The top two are indeed eye stalks, and the bottom two are used for 'smelling'.

In that case, Gray, can we legitimately say:

This slug's got no nose!
Got no nose? Then how does he smell?
With his eyes! Boom-boom!
