Mollusc shellThe mollusc (or mollusk) shell is typically a calcareous exoskeleton which encloses, supports and protects the soft parts of an animal in the phylumMollusca, which includes snails, clams, tusk shells, and several other classes. In this phylum, the shell takes on various forms: in Gastropoda, many species bear the archetypical coiled shell of snails, while Bivalvians typically have two shells known as valves.Gadilida
DentaliidaDentaliida is one of the two orders of scaphopodmollusks, commonly known as elephant's tusk shells.
MolluscaPhylum of invertebrate animalsCornu aspersum (formerly Helix aspersa)—a common land snailShell of Marisa cornuarietis, a freshwater snailMollusca is a phylum of protostomicinvertebrateanimals, whose members are known as molluscs or mollusks (). 86,600 extantspecies of molluscs are recognized, making it the second-largest animal phylum after Arthropoda.Fissidentalium
Marine invertebratesMarine animals without a vertebral columnErnst Haeckel's 96th plate, showing some marine invertebrates. Marine invertebrates have a large variety of body plans, which are currently categorised into over 30 phyla.Marine invertebrates are invertebrateanimals that live in marine habitats, and make up most of the macroscopic life in the oceans.
Marine lifeMarine life, which is also known as sea life or ocean life, refers to all the marine organisms that live in salt water habitats, or ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the seawater of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons, estuaries and inland seas.
Common nameIn biology, a common name is a name of a taxon or organism that is based on the normal language of everyday life. It may happen that the same name is used for different organisms in different regions ("robin" is used for several unrelated species of birds), or that the same organism is referred to by different names (cougar, puma, mountain lion, panther); and different languages use different names (cat, gato, chat, 貓...) Many, but not all, organisms have a common name.
Cosmopolitan distributionIn biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and environmental conditions, though this is not always so.
PhylumIn biology, a phylum (, ; pl.: phyla) is a level of classification, or taxonomic rank, that is below kingdom and above class. Traditionally, the term division has been used in botany instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent.Substrate (biology)In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives. A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae. Inert substrates are used as growing support materials in the hydroponic cultivation of plants.
Class (taxonomy)In biological taxonomy, class (Latin: classis) is a taxonomic rank, as well as a taxonomic unit (i.e., a taxon) in that rank. It is a group of related taxonomic orders. Other well-known ranks in descending order of size are domain, kingdom, phylum, order, family, genus, and species, with class ranking between phylum and order.*As an Amazon Associate I earn from qualifying purchases.
