Habitat and Adaptation | WWF
The climate, the kinds of food plants that grow in it, other animals that may be predators or Visit the link for a brief overview of how animals adapt to their habitat. Some animals, like the apple snail, can survive in different ecosystems- from. A snail is, in loose terms, a shelled gastropod. The name is most often applied to land snails, Many snails are herbivorous, eating plants or rasping algae from surfaces Several species of the genus Achatina and related genera are known as than that there is little morphological difference between slugs and snails. Relationships between fungus-farming animals and fungi are models of how When grazing live plants, however, snails do not consume live tissue directly; .. Beds and Their Relationship to Adjacent Habitats (U.S. Fish and Wildlife Service, .
Around 40—60 million years ago, three distinct insect lineages, ants, termites, and beetles, independently evolved the characteristic of cultivating fungi for nutrition 6.
Fungus-growing behavior evolved only once in ants 7 and termites 8whereas it evolved at least seven times in beetles 9 — There has been remarkable radiation within these insect lineages, and evolution of fungus-growing behavior is thought to be a major force driving each radiation 67. Development of fungal cultivation has also enabled these insects to rise to major ecological importance in a variety of terrestrial communities e.
Despite obvious success afforded by fungus-growing behavior, evolution of fungiculture is thought to have occurred only in these three distinct, terrestrial insect lineages 6.
In detritus-based marine systems, fungi that grow on dead plant material are a primary food source for invertebrate grazers 14 — Fungal supply to grazers is thought to be a bottom-up process largely dependent on the availability of dead plant mass 14 However, significant abrasion by grazers can facilitate both the invasion and growth of nutritious fungi In salt marshes along U.
Fungal farming in a snail
Long thought to be strictly a detritivore, recent research has shown that Littoraria actively grazes live salt marsh cordgrass, Spartina alterniflora In agriculture There are a variety of snail-control measures that gardeners and farmers use in an attempt to reduce damage to valuable plants.
Traditional pesticides are still used, as are many less toxic control options such as concentrated garlic or wormwood solutions. Copper metal is also a snail repellent, and thus a copper band around the trunk of a tree will prevent snails from climbing up and reaching the foliage and fruit.
Placing crushed egg shells on the soil around garden plants can also deter snails from coming to the plants. However, this is not without problems, as the decollate snail is just as likely to attack and devour other gastropods that may represent a valuable part of the native fauna of the region.
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.
What Do Snails Need to Live? | Sciencing
Coppiced wine-grape vines are often used for this purpose. The snails are then prepared for cooking. Their texture when cooked is slightly chewy. As well as being relished as gourmet food, several species of land snails provide an easily harvested source of protein to many people in poor communities around the world.
Many land snails are valuable because they can feed on a wide range of agricultural wastes, such as shed leaves in banana plantations. In some countries, giant African land snails are produced commercially for food. In certain parts of the world, snails are fried.

For example, in Indonesiathey are fried as sataya dish known as sate kakul. The eggs of certain snail species are eaten in a fashion similar to the way caviar is eaten.
In Bulgariasnails are traditionally cooked in an oven with rice or fried in a pan with vegetable oil and red paprika powder. Before they are used for those dishes, however, they are thoroughly boiled in hot water for up to 90 minutes and manually extracted from their shells. The two species most commonly used for food in the country are Helix lucorum and Helix pomatia.13 Amazing Snail Facts
Famine food Snails and slug species that are not normally eaten in certain areas have occasionally been used as famine food in historical times. A history of Scotland written in the s recounts a description of various snails and their use as food items in times of plague. A research study suggested that secretions produced under stress by Helix aspersa might facilitate regeneration of wounded tissue.
In Christian culture, it has been used as a symbol of the deadly sin of sloth.
