Cookia kawauensis is an extinct species of sea snail, a marine gastropod mollusk, in the family Turbinidae, the turban snails. [1]
This species occurs in New Zealand. [1]
A snail is, in loose terms, a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called slugs, and land snails that have only a very small shell are often called semi-slugs.
The gastropods, commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Neogastropoda is a clade of sea snails, both freshwater and marine gastropod molluscs.
Heterobranchia, the heterobranchs, is a taxonomic clade of snails and slugs, which includes marine, aquatic and terrestrial gastropod mollusks.
The operculum, meaning little lid, is a corneous or calcareous anatomical structure like a trapdoor which exists in many groups of sea snails and freshwater snails, and also in a few groups of land snails; the structure is found in some marine and freshwater gastropods, and in a minority of terrestrial gastropods, including the families Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc.
Sea snail is a common name for slow moving marine gastropod molluscs usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell.
Cypraeoidea, the cowries and cowry allies, is a superfamily of sea snails, marine gastropods included in the clade Littorinimorpha. This superfamily had been called Cypraeacea and was named by Rafinesque in 1815.
Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.
Sigmurethra is a taxonomic category of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This is an informal group which includes the majority of land snails and slugs.
Cookia sulcata, or Cook's turban, is a species of large sea snail, a marine gastropod mollusc in the family Turbinidae, the turban snails.
Cookia is a genus of large sea snails, marine gastropod molluscs in the family Turbinidae, the turban snails.
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung. Most feed on algae, but many are detritivores and some are filter feeders.
Astraea is a genus of medium to large sea snails, marine gastropod mollusks in the family Turbinidae, the turban snails.
Conus crotchii is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.
Dolicholatirus is a genus of sea snails, marine gastropod mollusks in the subfamily Peristerniinae of the family Fasciolariidae, the spindle snails, the tulip snails and their allies.
Bolma jacquelineae is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails.
Alvania grancanariensis is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae.
Terrestrial molluscs or land molluscs (mollusks) are an ecological group that includes all molluscs that live on land in contrast to freshwater and marine molluscs.
Maurea delli is a species of sea snail, a marine gastropod mollusk, in the family Calliostomatidae within the superfamily Trochoidea, the top snails, turban snails and their allies.
