Theba pisana snails aestivating on Foeniculum vulgare in Montbazin, France. Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter.
When the temperature falls below 7 °C (45 °F), snails hibernate. Under 12 °C (54 °F) the snails are inactive, and under 10 °C (50 °F), all growth stops. When the temperature rises much above 27 °C (81 °F) or conditions become too dry, snails estivate. Wind is bad for snails because it speeds up moisture loss, and snails must retain ...
The practice of rearing snails for food is known as heliciculture. For purposes of cultivation, the snails are kept in a dark place in a wired cage with dry straw or dry wood. Coppiced wine-grape vines are often used for this purpose. During the rainy period the snails come out of hibernation and release most of their mucus onto the dry wood/straw.
Some snails like the Euglandina rosea, or rosy wolfsnail, are carnivorous and prey on other snails. [15] However, most land snails are herbivores or omnivores. [16] Among land snails, there is also a large variation in preference for specific food. For example, Cepaea nemoralis, or the grove snail, prefers dead plant material over fresh herbs ...
The largest living species is the Giant African Snail or Ghana Tiger Snail (Achatina achatina; Family Achatinidae), which can measure up to 30 cm. [13] [14] The largest land snails of non-tropical Eurasia are endemic Caucasian snails Helix buchi and Helix goderdziana from the south-eastern Black Sea area in Georgia and Turkey; diameter of the ...
The grove snail, brown-lipped snail or lemon snail (Cepaea nemoralis) is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc. [3] It is one of the most common large species of land snail in Europe, and has been introduced to North America. Subspecies. Cepaea nemoralis etrusca (Rossmässler, 1835) [4]
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]
Physella acuta is a relatively common freshwater aquarium pest. It usually spreads by laying its eggs on plants which are then bought and taken home. Physella acuta can be annoying and reproduce quickly compared to other snails. It is generally non-harmful to the aquarium, but often found to be unsightly as well as adding to the aquarium's ...
