Counting snail shell rings When we investigated the population of these snails in the United Kingdom, we were able to find out the age of these snails. That's because as they get older, you can count the growth rings on the edge of their shell. Some snails were at least 6 years old, probably 8 or 9 years old. 17th. 2019г. If you have lips on the edges, you can say that the garden snail is old. Some species, such as the large Roman snail, take a much longer time (about 3 years) to become an adult. However, like most other high-breeding species, only a small portion of the laid eggs become snails. Seashells continue to grow with snails throughout their lives, and their rings are an indicator of their age. The entire snail life cycle is not that long from a human point of view. A snail can live for 2-7 years, depending on its species, but in captivity life expectancy is extended to 10 or 15 years. Snails, biologists have two experimental technique options. The first is the use of a "growth chart" that provides individuals of species according to their size by measuring mollusks. Therefore, I have an idea for his age the smallest. Slow growth is enough because the estimate is wrong!
How can I find out the age of a snail in the garden?

How do you identify snails in the form of shells?
First, the number of swirls helps determine between species. Profile swirls and their comparative sizes often help, some snails are very ventricular, others are very thin, some have huge body swirls, others are more It has a swirl that increases evenly. Therefore, a plan view of the shell will help you evaluate this.
How long is the snail shell's lifespan?
Life expectancy of snails depends on their habitat and species. Some of them live only about 5 years. However, other people in captivity can live up to the age of 25. The next question is, can the snail leave its shell?
How do you count the swirls of snail shells?
There are several ways to count the number of snail shell swirls. This section describes the most commonly used methods described by Pilsbury (1939). Before counting the swirls, you need to draw a fictitious line across the shell, as shown in Figure 7 below.
How do you know the age of a snail?
The older the snail, the thicker the lips, the lighter the color of the shell, and the whiter the surface of the shell between the bases of the sides of the lips. Snail age can be easily assessed by counting the number of winter vacations and adding this to the annual increment.
How long is the life of a snail?
Snail Lifespan Most wild snails typically have 2-5 years, but some large species can live up to 15 years. However, if you find a snail in your garden and decide to take care of it as a pet, there is no way to know how old it is.
How long can you keep a snail as a pet?
As a pet that takes care of snails, you can keep snails alive anywhere for 5 to several years.
