Do you know why slugs have slime? They use it to suction power and to travel upside down and up trees and other vertical surfaces. They leave a slime trail behind them as they move. When in danger the slug will emit a thick mucus coating and make their body shorter and fatter! This makes it difficult to eat them and gives them a coating with an unpleasant taste to potential predators. Slugs can fit into almost any space due to their ability to become very long and thin or short and fat. Their slime helps them fit through tight squeezes. They can avoid sunlight by crawling into small crevices and holes. Their slime also helps keep water in their bodies an important factor in their survival.
Mating rituals of banana slugs take place in the thick blanket of slime. Banana slugs sometimes eat each other slime before mating! Slugs have been eating slime and debris collected in their tails. It is possible that slime could be nutritional! Slugs actually have no backbone. There are different types of slugs. There is the common garden slug, the black slug and the gray field slug. Slugs are vegetarians so they eat plants. Slugs move by using a long and very strong foot. Slugs are invertebrates belonging to the scientific classification “Phylum Mollusca” and are closer to the octopus family. Slugs will come out at night and prefer wet, cool conditions. Spring is their favorite season.
It is a fact that birds, ducks, moles and beetles eat slugs. Some slugs are actually very sensitive to wind and can dehydrate and die if caught in a wind. Slugs live underground and absorb moisture through the dirt. The older slugs are usually females. Slugs are also sensitive to changes in temperatures and they can tell when it’s changed as little as a couple Fahrenheit. Slugs actually lay eggs. Slugs have four noses! That would explain the slime! Slugs can stretch themselves out to 11 times their body length. Slugs can be found on land and in the ocean. Slugs do have shells but they are small and under the skin on their backs. Slugs follow their own slime trails and that of other snails creating intricate pathways.
Slugs have both male and female reproductive parts so they can mate themselves. Slugs will hibernate like bears during the winter months. Slugs have a membrane that allow them to drink water from anywhere on their body. If you dump salt on a slug it will melt because of the osmotic process through their skin. The water will leave their body and dehydrate them and they will die. However, be careful because nothing will grow where you put the salt.
