The life expectancy of freshwater snails is up to one year, but some specimens can live up to five years. However, they are not around as much as terrestrial snails. But, in this case, their reproduction is impressive because they are actually capable of fertilizing their own eggs. Similar to land snails, freshwater snails are hermaphrodites. This mollusk has successfully colonized puddles, lakes, lagoons, and rivers throughout the world, as 4,000 species exist. What You Need To Know About Freshwater Snails

Among them are other species of mollusks, snakes, toads, and various species of birds. Most snail deaths are due to parasites or predators, which are relatively abundant. There are species, however, that have managed to live up to 30 years. However, they cannot be self-fertilized, so they must copulate to reproduce.Ī land snail’s life expectancy can vary quite a bit between species, but they usually last more than two years and reach around seven years. The terrestrial snails are hermaphrodites. In addition, these types of snails have two pairs of retractable tentacles: one is equipped with eyes, while the other allows it to sense the objects around it. In comparison, only a few species of water can breathe air. One of the significant differences between aquatic and land snails is that the second one breathes in atmospheric oxygen, which then passes to a lung. It protects their very soft body and internal organs, such as the lung. This singular characteristic is a rigid structure made of calcium carbonate. Additionally, they carry a shell that protects most of their body, which enables them to hide from predators. This helps them to climb up on surfaces that are inclined or rough. Land snails are well known to use a kind of “mucus” or “slime” to navigate their way around.

The first type is better adapted to the sea or freshwater bodies, but the second one lives solely on land, although in humid areas. Many kinds of snails exist, but they can be distinguished by being aquatic or terrestrial.
