Taxonomy

The overall taxonomy of the group is generally agreed on, but the relative Linnéan ranks are still a matter of discussion.

This is one of eleven recognised subfamilies in the family Pyramidellidae (according to the taxonomy of Ponder & Lindberg, 1997). Pyramidellidae, Common name the pyram family, or pyramid shells, is a voluminous Taxonomic family of mostly small and minute

In the taxonomy of Schander, Van Aartsen & Corgan (1999) it is a part of the family Turbonillidae.

In the taxonomy of Bouchet & Rocroi (2005), this subfamily comprises the subfamilies Cingulininae and Eulimellinae, that have been downgraded to the rank of tribe. Cingulininae is a Taxonomic Subfamily of very small sea Snails, marine Gastropod Mollusks It is one of eleven recognised Eulimellinae is a Subfamily of minute sea Snails marine Gastropod Molluscs in the family Pyramidellidae, the pyrams The new Gastropod Taxonomy of Bouchet & Rocroi (2005 (in collaboration with J In Biology, a tribe &mdashor infrafamily&mdashis a Taxonomic rank between family and Genus.

According to Schander, Van Aartsen & Corgan (1999) there are 27 genera within the Turbonillinae.

Shell description

The shell of these snails has a blunt, heterostrophic protoconch, which is pointed sideways. A protoconch (meaning first or earliest or original shell is an Embryonic or Larval shell of some classes of Molluscs e The shell of most species are rather high and slender.

The texture of these shells is usually ribbed sculptured in various forms and often also have more or less prominent spirals. Sculpture on a Mollusc shell is whatever natural 3-dimensional ornamentation exists on the outer surface of a shell apart from the basic shape of the shell itself Their color is mostly white, cream or yellowish, sometimes with red or brown lines.

The adult shell, the teleoconch is dextrally coiled, but the larval shells are sinistral. A larva ( Latin; plural larvae) is a juvenile form of Animal with indirect development, undergoing Metamorphosis (for example This results in a sinistrally coiled protoconch. The opening of the shell, the aperture is closed by a lid, a so called operculum. The operculum, meaning little lid (plural opercula or operculums is a corneous or Calcareous structure which exists in some groups of marine freshwater and land

Life habits

The Turbonillinae are ectoparasites, feeding mainly on other molluscs and on annelid worms. Parasitism is a type of symbiotic relationship between Organisms of different Species. A worm is a common name given to a diverse group of invertebrate animals that have a long soft body and no legs

They do not have a radula. The radula is a toothed Chitinous ribbon typically used for scraping cutting and chewing food before it enters the Esophagus. Instead their long proboscis is used to pierce the skin of its prey and suck up its fluids and soft tissues. In general a proboscis (from Greek προ pro "before" and βοσκειν boskein "to feed" also known as probiscus The eyes on the grooved tentacles are situated toward the base of the tentacles. Between the head and the foot, a lobed process called the mentum ( = thin projection) is visible. The mentum refers to a projecting structure near the mouth of any of several animals In Insects the mentum is the distal part of the labium.

These molluscs are hermaphrodites. A hermaphrodite is an organism having both male and female reproductive organs
