Slug Anatomy 101
Labels and design: Heather Stanley, OAN
Want to know your way around a slug? Let's start
at the top.
The mantle is a fleshy lobe that secretes the
shell in snails. It is vestigial in most slugs but useful for identification.
The keel (carina) is a backbone-like ridge that runs the length
of the back in some slug species. That blowhole on the side is called
the pneumostome and leads to the slug's lung. Slugs can swing their
two retractable, light-sensitive optical tentacles independently to gaze
at their surroundings. The optical tentacles are also used for
smell. The two lower sensory tentacles serve for feeling and tasting.
The mouth and teeth are on the underside of the head. The anus
is under the right side of the mantle as is the genital opening.
Running the length of the dorsal side of the slug is the foot whose bottom
is named appropriately, the sole. The foot sometimes wears a skirt.
