Knowra Gastropoda Gastropoda Gastropoda is the largest class of mollusks, including snails, slugs, limpets, and nudibranchs. Its members typically have a muscular foot and undergo torsion during development.
Mollusca : Mollusca is a phylum of invertebrates that includes snails, clams, octopuses, and their relatives. Gastropoda is one of the major classes within this phylum.
Gastropod locomotion : Gastropod locomotion is movement driven mainly by muscular waves in the foot, often aided by mucus. Foot movement explains how many gastropods glide over surfaces, including vertical ones.
Nudibranch : A nudibranch is a marine gastropod without a shell in its adult stage, often bearing exposed gills or cerata. Nudibranchs exemplify shell loss and conspicuous defenses among marine gastropods.
Biological control of agricultural pests : Biological control of agricultural pests uses organisms or their products to suppress crop-damaging species. Predatory gastropods have been introduced in some places to control pest snails, sometimes with harmful results.
Torsion (gastropod) : Torsion is the developmental rotation of a gastropod’s visceral mass and mantle cavity, typically by about 180 degrees. This distinctive developmental change helps define the gastropod body plan.
Gastropod feeding : Gastropod feeding encompasses strategies such as grazing, predation, suspension feeding, and parasitism. The radula and other feeding structures support an unusually broad range of diets.
Limpet : A limpet is a gastropod with a low, usually cap-shaped shell that clings tightly to surfaces. Limpets show how a simple shell shape can resist waves and predators.
Schistosomiasis : Schistosomiasis is a disease caused by parasitic flatworms whose life cycles include freshwater snails as intermediate hosts. Some gastropods sustain the parasite stages that transmit this human disease.
Gastropod foot : The gastropod foot is a muscular ventral body region used for locomotion, attachment, or burrowing. Its varied forms let gastropods crawl, cling, and move across many substrates.
Gastropod respiration : Gastropod respiration uses gills, a vascularized mantle cavity, or other surfaces to exchange gases. Different respiratory structures reflect gastropods’ transitions among aquatic and terrestrial habitats.
