What are gastropods classified as?

  • 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.

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 are three examples of gastropods?

Examples of common gastropods include all varieties of snails, abalone, limpets, and land and sea slugs.

Are gastropods herbivores?

The shells of some species are used as ornaments or in making jewelry. 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 is the classification of a snail?

Gastropods/Scientific names

How are mollusks classified?

Mollusks can be segregated into seven classes: Aplacophora, Monoplacophora, Polyplacophora, Bivalvia, Gastropoda, Cephalopoda, and Scaphopoda. These classes are distinguished by, among other criteria, the presence and types of shells they possess.

What are 3 characteristics of gastropods?

Major attributes:

  • Has become asymmetrical through torsion.
  • Ganglionated nervous system.
  • Reproduction varies – external fertilization and hermaphoditism.
  • Most species have a foot, visceral mass, mantle and mantle cavity.
  • Radula characteristic organ of Gastropoda.

What is the most common type of gastropod?

Snails
Snails have hard mineral shells; slugs lack shells. Because fossils mostly represent the hard parts of organisms, snails are the most common types of gastropod fossils. Slugs are not preserved as fossils. Snails have a single, coiled shell.

Is Snail a decomposer?

Both shelled snails and slugs can generally be categorized as decomposers, though they play only a small role compared to other decomposition organisms.

Is snail an omnivore?

Snails and slugs have evolved to eat just about everything; they are herbivorous, carnivorous, omnivorous, and detritivorous (eating decaying waste from plants and other animals). There are specialist and generalist species that eat worms, vegetation, rotting vegetation, animal waste, fungus, and other snails.

What is the scientific name for a snail?

Gastropods/Scientific names

Snail Species, Types, and Scientific Name The scientific name of the snail is Gastropoda. This is derived from two Greek words meaning “stomach” and “foot.” The scientific name refers to the position of the foot below the gut. Gastropods belong to the phylum of Mollusca.

How many species of gastropods are there in the world?

Publisher Summary. Gastropods are the most diverse class of the phylum Mollusca, comprising almost three quarters of the 110,000 or so species of molluscs known. Over 50,000 of these species belong to the mostly marine and freshwater Caenogastropoda while another 20,000 species belong to the subclass Pulmonata, of which most are terrestrial.

Which is a subclass of a marine gastropod?

Subclass Prosobranchia. Streptoneurous (twisted) gastropods with an anteriorly located mantle cavity (space lined with epidermis); operculum (protective cover) generally present; sexes separate; shell can usually hold entire animal; primarily marine, several freshwater and terrestrial groups; about 33,000 species.

What kind of environment does a gastropod live in?

Generally, the most ornate shells occur in tropical marine environments, but freshwater and terrestrial gastropods are often less ornate. Fig. 2. Some variations in shell form in the main groups of middle Paleozoic gastropods. (A) High-spired shell: Murchisonia coronata (Murchisonioidea).

Are there monophyletic clades in the gastropod group?

Graham gave an excellent review of anatomic and functional trends, concluding that many of the groups historically recognized as advanced are grades reached by several taxa independently, not monophyletic clades (groups with the same ancestor).
