Abstract
Most species of Mollusca live in salt water, on the shores of seas and lakes, and some in fresh
water; others are found in deserts, forests, and caves; there are 45,000 species. They are
invertebrate animals with lateral symmetry; they are slow-moving, but a few of them are fast,
like octopuses and squid, and some of them are of economic importance. The class Gastropoda is
considered the largest class belonging to the phylum Mollusca, as it contains more than 80%. Its
importance follows from its great diversity and spread in all environments. It has ecological
importance because it plays a great role in ecosystems due to the diversity of its food methods
between herbivorous and predatory. Studies on snails in Iraq are very few and modest. Hence the
idea of identifying these animals, studying their classification and life cycle, and collecting
samples in the early morning hours in home gardens and public gardens. A group of these snails
was found, and the most prevalent in these sites in Baghdad was chosen. It was classified and
pictures taken of it; then it was raised in an industrial environment, and after all, the appropriate
conditions were created for it. It was found that in Baghdad, this snail does not live more than
approximately 150 days on average, that the average duration of eggs hatching is approximately
14 days, that the resulting larvae survive only 40% of the time after hatching, and that those who
succeed in reaching puberty do not exceed 14% of the individuals. Its diameter ranges at puberty
at an average of 11 mm, and the number of turns of the shell is 5.5. This snail is distinguished by
a red lip at the opening of the shell. These animals, like others, are affected by their environment.
It was found that this species does not live more than a year, with an average of 195 days. As well as that it bears temperatures from 13–37 °C and that it produces eggs 4-5 times and 21–29
eggs each time.
