Thylacodes zelandicus is a species of sea snail, a worm snail or worm shell, a marine gastropod mollusc in the family Vermetidae, the worm snails. This species was previously known as Serpulorbis zelandicus.
In biology, a species ( ) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.
Sea snail is a common name for snails that normally live in salt water, in other words marine gastropods. The taxonomic class Gastropoda also includes snails that live in other habitats, such as land snails and freshwater snails. Many species of sea snails are edible and exploited as food sources by humans.
Family is one of the eight major hierarcical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".
The Trochidae, common name top-snails or top-shells, are a taxonomic family of very small to large sea snails, marine gastropod molluscs in the clade Vetigastropoda.
Haustrum is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails.
Atlanta is a genus of pelagic marine gastropod molluscs in the family Atlantidae. They are sometimes called heteropods.
Phenatoma is a genus of predatory sea snails, marine gastropod mollusks in the family Borsoniidae.
Phenatoma rosea, or the pink tower shell, is a species of predatory sea snail, a marine gastropod mollusc in the family Borsoniidae.
Batillaria is a genus of small salt marsh or mudflat snails, marine gastropod mollusks in the family Batillariidae, the horn snails.
Siliquaria, common name the slit worm snails, is a genus of sea snails, marine gastropod molluscs in the family Siliquariidae.
The Vermetidae, the worm snails or worm shells, are a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Littorinimorpha. The shells of species in the family Vermetidae are extremely irregular, and do not resemble the average snail shell, hence the common name "worm shells" or "worm snails".
Thylacodes aotearoicus is a species of sea snail, a worm snail or worm shell, a marine gastropod mollusc in the family Vermetidae, the worm snails. This species was previously known as Serpulorbis aotearoicus.
Stephopoma is a genus of sea snails, marine gastropod molluscs in the family Siliquariidae, the "slit worm shells" or "slit worm snails".
Stephopoma roseum is a species of sea snail, a marine gastropod mollusc in the family Siliquariidae, the slit worm snails.
Cerithiopsidae are a family of very small and minute sea snails, marine gastropod molluscs or micromollusks in the informal group Ptenoglossa. Gastropods in this family are known as cerithiopsids.
Turritriton is a genus of medium-sized sea snails, marine gastropod molluscs in the family Cymatiidae. This is often still regarded merely as a subgenus of the genus Cymatium.
Lottiidae is a family of sea snails, specifically true limpets, marine gastropod mollusks in the superfamily Lottioidea and the clade Patellogastropoda.
Crepidula, common name the slipper snails, slipper limpets or slipper shells, is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae. This family includes the slipper snails (Crepidula), hat snails (Calyptraea), spiny slipper snails (Bostrycapulus), and cup-and-saucer snails (Crucibulum) as well as Crepipatella, Siphopatella, Grandicrepidula, and Maoricrypta.
Patella is a genus of sea snails with gills, typical true limpets, marine gastropod mollusks in the family Patellidae, the true limpets.
Austrolittorina cincta is a species of sea snail, a marine gastropod mollusk in the family Littorinidae, the winkles or periwinkles, found in and endemic to New Zealand. Commonly called the brown periwinkle, or ngaeti in the Māori language. Although present in all parts of the country, it is more common in the south. Size up to 15mm in length.
Bembicium auratum is a species of sea snail, a marine gastropod mollusk in the family Littorinidae, the winkles or periwinkles.
Austrolittorina is a genus of sea snails, marine gastropod mollusks in the family Littorinidae, the winkles or periwinkles.
Thylacodes is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells. The species in this genus were previously placed in the genus Serpulorbis.
Arthur William Baden Powell was a New Zealand malacologist, naturalist and palaeontologist, a major influence in the study and classification of New Zealand molluscs through much of the 20th century. He was known to his friends and family by his third name, "Baden".
