Janthinoidea
Janthinoidea is a superfamily of sea snails containing wentletraps (Epitoniidae) and surfing snails (Janthinidae). It includes species that have tethered egg masses, some of which are used for flotation. Phylogeny Molecular evidence supports a tree for Janthinoidea that shows the sequential development of traits for a neustonic life. The wentletraps (Epitoniidae) have tethered egg masses that started to be used for flotation in ''Recluzia'' and then totally divorce from its original function for the ovoviviparous ''Janthina janthina''.

Triphoridae
Triphoridae is a family of very small sea snails, marine gastropod molluscs in the informal group Ptenoglossa, within the clade Hypsogastropoda. Almost all the species in this family are micromollusks and almost all are left-handed in shell-coiling.Bouchet, P. (2012). Triphoridae. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=131 on 2012-06-16 Distribution Species of this family can be found worldwide, but the major part occurs in the Indo-Pacific Region. Most species live between the intertidal zone and offshore to a depth between 200 m to 500 mm (exceptionally below 1,000 m). Shell description The shells of triphorids are small (between 2 mm and 10 mm - exceptionally 50 mm) and extremely high- spired, with numerous narrow whorls which often have distinctive sculpture. The majority of species in this family are left-handed or sinistral. Taxonomy Facts about their taxonomy are rather scant, complicated by ...

Informal Group (taxonomy)
An informal group in taxonomy is a taxonomic rank that is not well defined. This type of group can be paraphyletic or polyphyletic but is kept for ease, pending new systems of classification. In zoology Examples can be found in the classification of gastropods: Opisthobranchia, Sorbeoconcha, Hypsogastropoda, and Ptenoglossa are informal groups nearby the level of the order. In human taxonomy, the informal taxonomic rank of race is variously considered equivalent or subordinate to the rank of subspecies. In botany An alliance An alliance is a relationship among people, groups, or states that have joined together for mutual benefit or to achieve some common purpose, whether or not explicit agreement has been worked out among them. Members of an alliance are called ... is also considered an informal grouping of species,A taxonomic revision of Hebe informal group “ Connatae” (Plantaginaceae∗), based on morphology and flavonoid chemistry.

Sea Snail
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. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example species in the genus '' Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large group of animals and a very diverse one. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide when they can move around in the air. These air-breathing species includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Janthinidae
Wentletraps are small, often white, very high-spired, predatory or ectoparasitic sea snails, marine gastropod mollusks in the family Epitoniidae.Gofas, S. (2010). Epitoniidae. In: Bouchet, P.; Gofas, S.; Rosenberg, G. (2010) World Marine Mollusca database. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=132 on 24 April 2011 The word ''wentletrap'' originated in Dutch (''wenteltrap''), and it means spiral staircase. These snails are sometimes also called "staircase shells", and "ladder shells". The family Epitoniidae belongs to the superfamily Epitonioidea. Since 2017 this family also includes the former families Janthinidae (the pelagic purple snails) and Nystiellidae, all part of the informal group Ptenoglossa. Epitoniidae is a rather large family, with an estimated number of species about 630.
