Snails are one of the earliest known types of animals in the world. There is evidence that they evolved more than 600 million years ago. They are able to adapt to a variety of living conditions and they don’t require large amounts of food. They have been able to continually evolve to survive the conditions around them which many researchers find to be very fascinating. All snails are classified as mollusks because of the hard shell that protects their bodies. Many people confuse slugs as snails but they aren't in the same category due to the fact that they don’t have shells. You will find that there aren't any shortages of snails around the world. In fact they range number two behind insects when it comes to their numbers. As a result they are found in many locations and have a very diverse type of habitat where they can be found. Snails are very small animals that are only a few inches long and often weigh only a few ounces. A common mistake though is that the term snail is used to cover all of the different species. What you will find when you start looking at them though is that there are quite a few differences including where they live, what they eat, their behaviors, and of course the overall design of their bodies. As a snail moves it leaves behind a trail of slime. This allows it to easily move across any type of terrain without injuring its body. They aren't able to hear at all so they rely on their sense of touch to interact with each other. They use their sense of smell to help them find food. You will find that snails are the most active at night. They may come out during the early morning hours as well. Don’t waste your time trying to tell the males and females apart. This is because snails are hermaphrodites meaning they have the ability to produce both sperm and eggs. When they are mating they will both conceive and lay eggs.
