Usually they lay 20-50 eggs in rotting wood or below decaying leaves. Eggs are white and flattened, measure about 1 mm and hatch after 10–30 days. These gastropods reach their maturity only in the second or third season and can live 2–3 years. [3] Unlike many terrestrial snails they do not have a sex dart. [4]
The mating of gastropods is a vast and varied topic, because the taxonomic class Gastropoda is very large and diverse, a group comprising sea snails and sea slugs, freshwater snails and land snails and slugs. Gastropods are second only to the class Insecta in terms of total number of species.
Cantareus apertus, [2] commonly known as the green garden snail, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae, the typical snails. Distribution
Rumina decollata is a voracious predator, and will readily feed upon common garden snails and slugs and their eggs. The snail eats plant matter as well, but this generalist predator is indiscriminate in its feeding and has been implicated in the decimation of native gastropods (including non-pest species) and beneficial annelids.
Although snails infected by other Leucochloridium species are reported to continue to reproduce, [3] snails infected by L. paradoxum often show a reduction of the sexual organs. [ 6 ] The appearance and behaviour of the sporocysts is a case of aggressive mimicry , where the parasite vaguely resembles the food of the host, thereby gaining the ...
The snails are a unique part of the neuston, organisms which live on or near the surface of the water, because of their relatively large size. They have veliger , or free swimming larvae, but the adults do not swim, and cannot create their rafts, except at the surface where air bubbles are available.
The individual in the photograph has a shell which is 45.5 mm long. The whole snail weighs 3.2 g live. Almost all the species of snails in the family of door snails are left-handed, which is an uncommon feature in gastropod shells in general. These snails have shells which are extremely high-spired, with numerous whorls.
Otala lactea, known as the milk snail or Spanish snail, is a large, edible [3] species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk, in the family Helicidae, the typical snails. [4] Archaeological recovery at the Ancient Roman site of Volubilis, in Morocco, illustrates prehistoric exploitation of O. lactea by humans. [5]
