Why do slugs have four noses?

Slimy as they are, slugs belong to the millions of creatures found in nature that are perceived by humans to be sanely disgusting. Slugs are typically snail like creatures that are not contained in a shell. They are legless, long, mollusks and opt to find food and feed at night. The slime trail that they make is because of the fact that they are creatures greatly depending on the presence of moisture and they move only by means of gliding motion. Slugs develop by undergoing the process called the torsion, wherein they move in a one hundred eighty degree twist. Reaching to full maturity, they start to invade gardens or other soil materials, where they can fully thrive and grow well. With greater preference in living in warm, moist areas, slugs evidently become less active when cooler weather starts to set in. They become dormant but is able to regain their active state when moist warm weather begins setting in again.

Pests as they are, slugs were further studied, particularly their parts and its respective functions. It was then discovered that slugs have four noses. Although these noses do not function as that with humans, these noses are more often considered as appendages, which are found to be sensitive to heat and other types of stimuli. Despite being called noses, slugs do not actually have noses. These appendages were found to function as the organs for smelling of chemicals in the water. Further studies have been done and it was discovered that that there are two upper sensors, that detect or sense light, and the lower, are for smelling with.

Unique and interesting as they are, slugs have been known to greatly contribute to creating agricultural damage to crops and many other growing vegetation.
