Detailed explanation-1: -The marine shelled species of gastropods include species such as abalone, conches, periwinkles, whelks, and numerous other sea snails that produce seashells that are coiled in the adult stage-though in some, the coiling may not be very visible, for example in cowries.

Detailed explanation-2: -Gastropods are a highly diverse Class of molluscs that include limpets, whelks, periwinkles, abalones, venomous cone shells, and the shell-less nudibranchs, sea slugs and sea hares.

Detailed explanation-3: -The Class Gastropoda (in Phylum Mollusca) includes the groups pertaining to snails and slugs. The majority of gastropods have a single, usually spirally, coiled shell into which the body can be withdrawn. The shell of these creatures is often what is recovered in a fossil dig.

Detailed explanation-4: -Snails and slugs are known as gastropods, which mean ‘stomach foot’. This describes the way in which the body and internal organs of slugs and snails has been twisted back so that the stomach lies above the large fleshy foot of these animals.
