How about a snail? Some of you may be thinking, "Who would have a snail for a pet? After all, they're not furry and cuddly, and they move really slowly. And then there's also the slime issue. If you've ever seen a snail or its cousin, the slug in the wild, you've probably noticed that tell-tale trail of slime they leave behind as they move slowly across the grass or a leaf.Can you imagine constantly finding trails of slime across your bedroom floor or pillow? So what's up with all that snail slime? Snails are gastropods. Since "gastro" means stomach and "pod" means foot , a snail is essentially a "stomach foot. Snails produce slime , which is a kind of mucus , via a special gland on the front of the snail's foot.Scientists initially thought that the purpose of the slime was to enable snails to move. Over the years, however, researchers have learned that snail slime is a special substance with unique properties and several purposes. Snail slime has the consistency of a liquid gel. At rest , it's solid and sticky. Under pressure , though, it liquefies and acts as a lubricant. Although their slime definitely helps them to move along more efficiently , snails don't need it to move. They have muscles on the underside of their feet that generate pulses that propel them forward.As they travel on the slime they produce, the slime helps them to stick to whatever surface they're on while their muscles are at rest. As their muscles contract and push down to propel them forward, however, the slime becomes more liquid and makes movement easier.Slime is particularly handy when snails climb vertical surfaces and even travel upside-down. In these instances, the slime 's sticky properties help snails cling to surfaces, seeming to defy gravity! Snails constantly produce slime , even when they're not moving. When they do move, they leave a trail of slime that can appear as a silvery track on various surfaces.When they're not moving, the slime serves another important purpose. In addition to helping them move, their slime helps to protect snails' skin from environmental hazards, such as sharp objects, bacteria , and the Sun's ultraviolet rays. In dry weather, snails can curl up in their shells and seal themselves inside using their slime. This helps them to stay moist and comfortable even when the weather threatens to dry them out.We hope you enjoyed today's slimy Wonder of the Day!

Outside, they live under stones and in nooks and crannies in the garden where they hide during cold or sunny weather.

Slugs have a good sense of smell and are often attracted to pet food, kitchens or pantries. Being invertebrates, they have the advantage of being able to squeeze through the tiniest of cracks or crevices — space under doors or between floorboards, joints along walls, holes drilled for pipes or wiring; they can even climb vertically or upside down.So how do you keep them out?
