Blue Mystery Snail: Care Guide & Species Profile - Animascorp (2022)

What is blue mystery snail?

Blue Mystery Snail is a name given to the species Lymnaea stagnalis by some people who are interested in its biology and behaviour. It is also known as the Common Pond Snail or simply pond snail.

The common name of this animal comes from its habit of living in ponds, lakes and other water bodies. The scientific name comes from the fact that the shell has two colours (pink and brown) and the animal itself is usually dark greyish-brown with pink spots on its back.

The snail lives in colonies that can be found around the world. They have been recorded in many countries including Australia, China, France, Germany, India, Japan, New Zealand, South Africa, Spain, Sweden, Switzerland, United Kingdom and USA.

It is a hermaphrodite and lays eggs every 2 weeks. The female lays about 30 eggs at one time. These eggs hatch after 3 days and the newly hatched snails look like miniature versions of their parents. After hatching they stay together for about four months before separating into different groups.

They feed on algae, diatoms, small invertebrates such as worms, insects and crustaceans. They eat up to 4 times their body weight per day.

They live about three years but may reach 10 years if kept in captivity. Their lifespan is much shorter in the wild where they only live about six months.

Their shells are made out of calcium carbonate and are very hard and strong. They are used as jewellery and decorations.

They are sometimes eaten by humans because they taste good when cooked. A few people even keep them as pets. They are not harmful to humans and do not transmit any diseases.
