Yellow slugs, like the majority of other land slugs, use two pairs of tentacles on their heads to sense their environment. The upper pair, called optical tentacles, is used to sense light. The lower pair, oral tentacles, provide the slug's sense of smell. Both pairs can retract and extend themselves to avoid hazards, and, if lost to an accident ...
Parmacelloidea is a superfamily of air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora and the informal group Pulmonata. These are limacoid or keelback slugs.
Ambigolimax valentianus (also known as Lehmannia valentiana) is a species of terrestrial slug, a pulmonate gastropod mollusc in the family Limacidae. [6]It has spread very widely around the world, especially in greenhouses, where it can be a pest; in warmer climates it has often then spread outdoors.
It is an opening in the right side of the mantle of a stylommatophoran snail or slug. Air enters through the pneumostome into the animal's single lung , the air-filled mantle cavity. [ 1 ] Inside the mantle cavity the animal has a highly vascularized area of tissue that functions as a lung.
