Some gastropod species are terrestrial and have lungs for gas exchange, others are aquatic and use gills. The space near the entrance to the shell that is bound by the mantle is the mantle cavity. Aquatic gastropods have gills located in the mantle cavity. The mantle of terrestrial gastropods functions as a lung. The study of shell color polymorphism in marine gastropods cannot leave behind these new trends in evolutionary biology. For example, phenotypic plasticity in gastropods is an established fact (Bourdeau et al., 2015), and here we have seen some putative cases of plastic shell color polymorphism in marine gastropods. However, its role as an ... Mollusks are soft-bodied invertebrates of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body. Along with the insects and vertebrates, mollusks are one of the most diverse groups in the animal kingdom, with nearly 100,000 (possibly as many as 150,000) described species.This is a …Snails are not insects. They are members of the class Gastropoda, and are more closely related to squid than to the insects that live in gardens. Snails and slugs are both in the gastropod group, and there are members that dwell in marine o...

Gastropods are eaten by numerous animals, including various types of fish, birds, and mammals. They are also eaten by humans throughout the world.

A group of snails can be referred to as a rout, walk or escargatoire of snails. The word snail is used for thousands of animal species in the gastropod mollusk family. Snails are mollusks with a shell, which usually has a spiral or coiled s...Significant reduction of shell or total shell loss and assumption of a slug-like form occurs in approximately one third of the gastropod superfamilies. Predictably, this multiconvergent …Most gastropod shells are composed of an outer organic layer (periostracum) and an inner, mostly much thicker, calcified layer. The colour pattern typical of many gastropod shells (Figure 1) is formed by different organic pigments which are limited to the periostracum and the uppermost calcified layer. This shell feature, sometimes reflecting ... ….

Sacoglossa. Sacoglossa, commonly known as the sacoglossans or the " solar-powered sea slugs ", are a superorder of small sea slugs and sea snails, marine gastropod mollusks that belong to the clade Heterobranchia. Sacoglossans live by ingesting the cellular contents of algae, hence they are sometimes called "sap-sucking sea slugs".The mantle is the upper portion of a gastropod’s body. In shelled gastropods, it's the part of the body that always remains inside the shell. Internally, the mantle contains the visceral mass; externally it produces and secretes calcium carbonate and lime, which hardens into a protective shell in many gastropod species.

The Vermetidae, the worm snails or worm shells, are a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Littorinimorpha. [1] The shells of species in the family Vermetidae are extremely irregular, and do not resemble the average snail shell, hence the common name "worm shells" or "worm snails".gastropod. Gastropod - Reproduction, Life Cycles: The fertilized egg of gastropods hatches into a free-swimming form (trochophore larva). In some species, the swimming veliger stage persists for weeks or even months. Land gastropods exhibit internal fertilization. Egg production is correlated with the degree of care given to the eggs or young.
