Predatory gastropods as natural enemies of terrestrial gastropods and other invertebrates. It was during the Mesozoic era that the ancestors of many of the living gastropods evolved.

Bacterial and non-microbial diseases in terrestrial gastropods. They were stored at 4 °C and weighed and dissected consecutively within four weeks after collection. Gastropods exhibit an important degree of variation in mitochondrial gene organization when compared to other animals. This class comprises snails and slugs from saltwater, from freshwater, and from the land. There are sometimes also buccal ganglia.[22]. For trematodes the number of individuals (parasite load) did not differ among host species; for nematodes it was higher in A. vulgaris than A. fasciatus. The majority of gastropods have simple visual organs, eye spots either at the tip or base of the tentacles. To further compare the parasite susceptibility of the surveyed gastropods, we exposed A. vulgaris, A. fasciatus, and A. arbustorum to a slug parasitic nematode, Phasmarhabditis hermaphrodita, in the laboratory.

Continuing to use www.cabi.org  As of 2017[update], 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record.[6]. The main aspects of the life cycle of gastropods include: The diet of gastropods differs according to the group considered. Again, in some land snails, an unusual feature of the reproductive system of gastropods is the presence and utilization of love darts. Whenever monophyly has not been tested, or is known to be paraphyletic or polyphyletic, the term "group" or "informal group" has been used.

We found A. vulgaris to have the highest prevalence of both parasite groups (49% nematodes, 76% trematodes), which does not support the parasite release hypothesis, but rather points to A. vulgaris as a potentially important intermediate host of these parasites. [28], One of the earliest known terrestrial (land-dwelling) gastropods is Maturipupa, which is found in the Coal Measures of the Carboniferous period in Europe, but relatives of the modern land snails are rare before the Cretaceous period, when the familiar Helix first appeared.

Those gastropods without a shell, and those with only a very reduced or internal shell, are usually known as slugs; those with a shell into which they can partly but not completely withdraw are termed semi-slugs.

In the past, the taxonomy of gastropods was largely based on phenetic morphological characters of the taxa. A few sea slugs are herbivores and some are carnivores.

Other snails have adapted to an existence in ditches, near deepwater hydrothermal vents, the pounding surf of rocky shores, caves, and many other diverse areas.

The "Purbeck Marble" of the Jurassic period and the "Sussex Marble" of the early Cretaceous period, which both occur in southern England, are limestones containing the tightly packed remains of the pond snail Viviparus. In the older classification of the gastropods, there were four subclasses:[30].
