In terrestrial gastropods (land snails and slugs), the olfactory organs, located on the tips of the four tentacles, are the most important sensory organ. { bidder: 'openx', params: { unit: '539971065', delDomain: 'idm-d.openx.net' }}, Gastropods typically have a well-defined head with two or four sensory tentacles with eyes, and a ventral foot, which gives them their name (Greek gaster, stomach, and pous, foot). iasLog("__tcfapi removeEventListener", success); Sometimes the shell has a siphonal canal to accommodate this structure. In the case of the Gastropoda, the taxonomy is now gradually being rewritten to embody strictly monophyletic groups (only one lineage of gastropods in each group). } Some nudibranchs have smooth or warty backs with no visible gill mechanism, such that respiration may likely take place directly through the skin. storage: { Information and translations of gastropod in the most comprehensive dictionary definitions resource on the web.

This is speculated to have some evolutionary function, as prior to torsion, when retracting into the shell, first the posterior end would get pulled in, and then the anterior.

Some predatory carnivorous gastropods include, for example: Cone shells, Testacella, Daudebardia, Ghost slug and others. pbjs.setConfig(pbjsCfg); In the older classification of the gastropods, there were four subclasses:[30]. { bidder: 'ix', params: { siteId: '194852', size: [300, 250] }}, The radula of a gastropod is usually adapted to the food that a species eats. By the Carboniferous period many of the shapes seen in living gastropods can be matched in the fossil record, but despite these similarities in appearance the majority of these older forms are not directly related to living forms.

Gastropods can be accidentally transferred from one habitat to another by other animals, e.g. In the land slugs, the shell is reduced or absent, and the body is streamlined. They use the siphon primarily to "taste" the water to detect prey from a distance. In 2004, Brian Simison and David R. Lindberg showed possible diphyletic origins of the Gastropoda based on mitochondrial gene order and amino acid sequence analyses of complete genes.
