This sleeping behavior isn’t the only thing unique to snails, another unique character is that they mate differently in relation to fishes. Almost all snails are hermaphrodites, meaning that they both possess a male and female sexual organ but still pairing up is still needed for mating so that the eggs they produced can be fertilized successfully.

For locomotion snails use a “foot”. The foot is a muscular organ which is always expanding and contracting to bring about movement. The foot possess a unique gland which secretes mucus. This mucus secreted serves as a lubricant and glue, thereby allowing the snail to easily move across surfaces while also sticking to the surface in which they are.

The breathing of snails also differ from other species. Some species known as nerite snails make use of gills to extract oxygen from water, isn’t this a wonderful feature?

For nutrition, snails possess thousands of teeth which comes together to form a structure known as the radula. A single radula could have up to 120 rows, each containing a 100 teeth. This is a very effective tool for cutting and scrapping when feeding.

Snails are found across the globe but the highest number of species are located in the southeastern part of the United States. Another place where they are highly populated is the Lake Tanganyika located in Africa.

Snails do not have ears as part of their organs, but they have a very good eyesight which covers up for their lack of ears or inability to hear.

Pornacea maculata is the largest freshwater specie of snails, reaching almost a length of 6 inches. That is nothing compared to the African giant land snail known scientifically as Achatina achatina which has a massive length of 16 inches when fully stretched.

Almost 5000 freshwater species are found living in lakes, pond and rivers across the world. All of them are gastropod molluscs and they fall into the subclass pulmonata.
