Gastropods may be plant-eaters, carnivores, scavengers, deposit-feeders (obtaining food particles from sediment) or suspension-feeders (straining suspended food particles from the water. It is very difficult to determine if a snail is a herbivore or carnivore by looking at its shell.

Are gastropods herbivores or carnivores?
Some gastropods graze, some browse, some feed on plankton, others are scavengers or eat detritus while still others are carnivores. Gastropods lived on and around the Wenlock Reef. Some would have grazed on particles of detritus.
What food do gastropods eat?
Some gastropods are scavengers, feeding on dead plant or animal matter; others are predators; some are herbivores, feeding on algae or plant material; and a few species are external or internal parasites of other invertebrates.
What are 4 characteristics of gastropods?
The body of gastropods in general consists of four parts that are head, mantle (shell), muscular foot and a mass or hump of organs generally enclosed in a shell. Gastropods feed on plants, small insects, decaying matter or sometimes small organisms in water.
What type of consumers are gastropods?
Morphological, physiological and ecological evidence is used to show that terrestrial gastropods and isopods, although both can be considered as "primary consumers", deal quite differently with the vegetabilic matter they use as food.
What type of creature is a gastropod?
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 The majority of gastropods have a single, usually spirally, coiled shell into which the body can be withdrawn.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.
What makes something a gastropod?
The Class Gastropoda includes the snails and slugs. Most gastropods have a single, usually spirally coiled shell into which the body can be withdrawn, but the shell is lost or reduced some important groups. ... Gastropods have a muscular foot which is used for "creeping" locomotion in most species.
What are three examples of gastropods?
Examples of common gastropods include all varieties of snails, abalone, limpets, and land and sea slugs.
Are bivalves carnivores?
A few bivalves, such as the granular poromya (Poromya granulata), are carnivorous, eating much larger prey than the tiny microalgae consumed by other bivalves.
Do gastropods have a mantle?
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.
Is an octopus a gastropod?
Gastropods are the largest group of molluscs containing terrestrial, marine, and freshwater animals. ... Cephalopods include squid, octopuses, cuttlefish, and chambered nautiluses while gastropods include snails, conchs, abalones, whelks, sea slugs, and garden slugs.
Are gastropods invertebrates?
The gastropods (/ˈɡæstrəpɒdz/), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (/ɡæsˈtrɒpədə/). This class comprises snails and slugs from saltwater, from freshwater, and from the land.
How do you identify a gastropod?
Basic Identification and Features
What gives gastropods their signature look? Large foot, coiled shell, tentacles and the presence of torsion. Torsion is a unique characteristic where the body is twisted round in such a way that the reproductive organs, anus, gills and mantle cavity all point in a forward direction.
Is a nudibranch a gastropod?
nudibranch, also called sea slug, any of the marine gastropods that constitute the order Nudibranchia (subclass Opisthobranchia of the class Gastropoda). Nudibranchs possess a radular feeding organ, but they characteristically lack a shell, gills, and mantle cavity typical of other mollusks.
