'''నత్తలు''' (Snail) [[మొలస్కా]] జాతికి చెందిన ఒక రకమైన [[జంతువు]]లు.
 
 
The word '''snail''' is a [[common name]] that can be used for almost all members of the [[mollusca]]n class [[Gastropoda]] that have coiled [[animal shell|shell]]s in the adult stage. (Snails lacking a shell or having only a very small one are usually called [[slug]]s. Snails that have a broadly conical shell that is not coiled, or appears not to be coiled, are often known as [[limpets]].) When the word snail is used in a general sense, it includes sea snails, land snails and freshwater snails.
 
The class of Gastropoda (the snails and slugs) is second only to the [[insect]]s in terms of total number of [[species]]. Snails are extraordinarily diverse in [[habitat]], [[morphology (biology)|form]], [[ethology|behavior]], and [[anatomy]], and therefore what is true of one snail species may not at all be true of another.
 
Snails can be found in a wide range of different and alike environments from [[ditch]]es to [[desert]]s to the [[abyssal zone|abyssal]] depths of the sea. The great majority of snail species are [[marine biology|marine]]. Many others are [[terrestrial ecoregion|terrestrial]], and numerous kinds can be found in [[fresh water]], and even [[brackish]] water. Many snails are [[herbivore|herbivorous]], though a few land species and many marine species are [[omnivore]]s or [[predation|predatory]] [[carnivore]]s.
 
Although the average person might perhaps be more familiar with terrestrial snails, land snails are in the minority. Marine snails have much greater diversity, and a greater [[biomass (ecology)|biomass]]. Snails which [[respiration (physiology)|respire]] using a [[lung]] belong to the group [[Pulmonata]], while those with [[gill]]s form a [[paraphyly|paraphyletic]] group, in other words, snails with gills are divided into a number of [[taxonomy|taxonomic]] groups that are not very closely related.
 
Snails with lungs and with gills have diversified widely enough over geological time that a few species with gills can be found on land, numerous species with a lung can be found in freshwater, and a few species with a lung can be found in the sea.
 
Although the word snail is often used for all shelled gastropods, the word "snail" can also be used in a much more limited sense, to mean various larger species of air-breathing (pulmonate) land snails. The majority of this article is about air-breathing land snails.
