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''. Taxonomy Janthinoidea includes the following families, genera, and species. *Epitoniidae **'' Acrilla'' ***'' Acrilla acuminata'' **'' Alexania'' ***'' Alexania inazawai'' **'' Cirsotrema'' ***'' Cirsotrema multiperforata'' ***'' Cirsotrema varicosum'' **''Cycloscala'' ***'' Cycloscala crenulata'' **'' Epidendrium'' ***'' Epidendrium aureum'' ***'' Epidendrium sordidum'' **'' Epifungium'' ***'' Epifungium adgranulosa'' ***'' Epifungium adgravis ...

Janthina Janthina
''Janthina janthina'' is a species of holoplanktonic sea snail, a marine gastropod mollusk in the family Epitoniidae. Its common names include violet sea-snail, common violet snail, large violet snail and purple storm snail. Distribution This species is found worldwide in the warm waters of tropical and temperate seas, floating at the surface. More specifically, the species is located in the tropical and subtropical Atlantic, Indian and Pacific oceans. They are often found in large groups and sometimes become stranded on beaches when they are blown ashore by strong winds. The snails are a unique part of the neuston, organisms which live on or near the surface of the water, because of their relatively large size. They have veliger, or free swimming larvae, but the adults do not swim, and cannot create their rafts, except at the surface where air bubbles are available. Habitat These snails are pelagic, drifting on the surface of the ocean, where they feed upon pelagic hydrozoa, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epitonium Ancillotoi
''Epitonium'' is a genus of small predatory sea snails, marine gastropod mollusks. ''Epitonium'' is the type genus of the family Epitoniidae, the wentletraps.Bouchet, P.; Gofas, S. (2010). Epitonium Röding, 1798. 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=137943 on 2010-11-22 The common name wentletraps is derived from the Dutch word ''wenteltrap'', denoting a spiral staircase. This refers to the striking form and sculpture of the shells of the mollusks in this genus, and to a lesser extent, the whole family. The genus ''Epitonium'' has been divided in the past by some authors into several subgenera, but these subgenera were based only on shell characters and did not reflect the true underlying relationships or phylogeny. Shell description ''Epitonium'' shells are high-spired, and are all-white in most of the species within this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Janthina Cf
''Janthina'' is a genus of small to medium-sized pelagic or planktonic sea snails, marine gastropod molluscs in the family Epitoniidae.Gofas, S. (2011). Janthina Röding, 1798. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138092 on 2011-11-01 Distribution Species in this genus occur worldwide in tropical, subtropical and warm seas. Description These snails are pelagic and live at the surface of the ocean. Adult snails may not be capable of swimming, and die when they are detached from their rafts; ''Janthina janthina'' larvae, however, actively swim in the water column. The adult snails prey upon (and live near to) one of several species of pelagic animals loosely known as jellyfish. More specifically they eat the medusae of free-swimming Cnidaria, in particular the genus known as "by-the-wind sailors", ''Velella''. The snails are able to float securely because they create a raft of clear chitin around air bubble ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
