Like other pulmonate land gastropods, the majority of land slugs have two pairs of 'feelers' or tentacles on their head.  The slug mite, Riccardoella limacum, is known to parasitise several dozen species of mollusks, including many slugs, such as Agriolimax agrestis, Arianta arbustrum, Arion ater, Arion hortensis, Limax maximus, Milax budapestensis, Milax gagates, and Milax sowerbyi. Slugs are essentially the same thing as land snails; they are simply land snail species that do not develop visible shells. Millions of ‘killer slugs’ are set to invade gardens this spring. They can destroy foliage faster than plants can grow, thus killing even fairly large plants. But then there is a category of slugs known as the Wolf slug, which was once indigenous to Northern Africa. In drier conditions, they hide in damp places such as under tree bark, fallen logs, rocks and man-made structures, such as planters, to help retain body moisture. A container such as a margarine tub or large yogurt pot sunk … Several species of nematodes are known to parasitise slugs. Of course, slugs do have predators. The word slug is also often used as part of the common name of any gastropod mollusc that has no shell, a very reduced shell, or only a small internal shell, particularly sea slugs and semislugs (this is in contrast to the common name snail, which applies to gastropods that have a coiled shell large enough that the animal can fully retract its soft parts into the shell). "Ten new complete mitochondrial genomes of pulmonates (Mollusca: Gastropoda) and their impact on phylogenetic relationships". The nematodes are applied in water and actively seek out slugs in the soil and infect them, leading to the death of the slug. Some species of slugs, for example Tandonia budapestensis, have a prominent ridge running over their back along the middle of the tail (sometimes along the whole tail, sometimes only the final part).  Species of widely known medical importance pertaining to the genus Angiostrongylus are also parasites of slugs. Another endangered one is the snakeskin hunter slug that was once found widely in South Africa, the population of which has reduced drastically now. These pellets are defecated through the anus that’s situated above its head. But there haven’t been any reported incidents of a slug bite except for isolated instances. Slugs similar to earthworms are hermaphrodites, which means they have both male and female sex organs. Hi there! snails whose shells are too small for them to retract fully into) and slugs. However, slug slime can be harmful to dogs if it contains the lungworm parasite as it can lead to a dangerous infection.

Among the many slimy creatures seen in our backyard, slugs have the worst reputation because of their primary diet. The snails found in temperate countries (such as the U.S. or Europe) are not poisonous. The pellets are manufactured from cereal and yeast that lures the slugs and snails to them and they contain a poison that kills the slugs and snails after they have consumed the pellets.  Some colubrid snakes are known predators of slugs.  House flies in the family Muscidae, mainly those in the genus Sarcophaga, are facultative parasitoids of Arionidae.. The process of digestion starts with the slug scraping food off the leaves, trees, and mushrooms with the help of radula. Thanks to the global climatic change and to air travel, these wolf slugs managed to reach Europe and thrive there. They also feed on carrots, peas, apples, and cabbages too.   An internal shell is present in the Limacidae and Parmacellidae. The Oyster's Garter", "Penis-biting slugs: wild claims and confusions", "Feeding activities of slugs on Myxomycetes and macrofungi". High rainfall and suitable habitat enable slugs and snails to thrive in the UK, much to the annoyance of many gardeners. Because slugs are soft-bodied and require cool, moist conditions to survive, they avoid the sun during the day and hide under leaves, rocks, boards, and overturned pots in the garden. The digestive system of the family of slugs, in general, is comprised of a mouth, a radula, salivary glands and ducts, an esophagus, a stomach, a rectum, and an anus.  The taxonomy of this group is in the process of being revised in light of DNA sequencing.  One of its congeners, the Northwestern garter snake (Thamnophis ordinoides), is not a specialized predator of slugs but occasionally feeds on them. Apophallation allows the slugs to separate themselves by one or both of the slugs chewing off the other's or its own penis. , Belocaulus angustipes mating; note the white penis extending to the reproduction pore on the underside of the smaller slug, A banana slug eating a fly agaric, Amanita muscaria. Slugs and snails are the two among the many gastropods and it is interesting to note that some distant cousins of the slugs have developed a sluggy, shell-free shape. Slugs mainly feed on leaves of plants and dead and decayed organic matter with the help of specialized teeth. The muscles in the esophagus move in a rhythmic way known as peristalsis. Slugs are considered ‘poisonous’ if they have come into contact with poison baits containing the substance Metaldehyde. The redbelly snake (Storeria occipitomaculata) and the brown snake (Storeria dekayi) feed mainly but not solely on slugs, while some species in the genus Dipsas, Sibynomorphus (e.g. This organ generally serves as storage for calcium salts, often in conjunction with the digestive glands. When a slug has spotted a mate, they encircle each other. Slugs play an important role in the ecosystem by eating decaying plant material and fungi. Some sea slugs are toxic, but this sea slug has not previously been known to contain this particular toxin.

The shell-less condition has arisen many times independently during the evolutionary past, and thus the category "slug" is a polyphyletic one.

We get huge snails inside our bedroom, and if we don't notice they end up as empty shells stuck in obscure corners, having dried out with nothing to eat. Slugs' bodies are made up mostly of water and, without a full-sized shell, their soft tissues are prone to desiccation.
