Velella is a monospecific genus of hydrozoa in the Porpitidae family. Its only known species is Velella velella, a cosmopolitan free-floating hydrozoan that lives on the surface of the open ocean. It is commonly known by the names sea raft, by-the-wind sailor, purple sail, little sail, or simply Velella.
Glaucus atlanticus is a species of small, blue sea slug, a pelagic (open-ocean) aeolid nudibranch, a shell-less gastropod mollusk in the family Glaucidae.
Cone snails, or cones, are highly venomous sea snails of the family Conidae.
Wentletraps are small, often white, very high-spired, predatory or ectoparasitic sea snails, marine gastropod mollusks in the family Epitoniidae.
Mitridae, known as mitres or mitre shells, are a taxonomic family of sea snails, widely distributed marine gastropod molluscs in the clade Mitroidea.
Naticidae, common name moon snails or necklace shells, is a family of medium to large-sized predatory sea snails, marine gastropod molluscs in the clade Littorinimorpha. The shells of the species in this family are mostly globular in shape.
Pila is a genus of large freshwater snails with an operculum, African and Asian apple snails, aquatic gastropod mollusks in the family Ampullariidae, the apple snails.
Janthina is a genus of small to medium-sized pelagic or planktonic sea snails, marine gastropod molluscs in the family Epitoniidae.
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.
Porpita porpita, or the blue button, is a marine organism consisting of a colony of hydroids found in the warmer, tropical and sub-tropical waters of the Pacific, Atlantic, and Indian oceans, as well as the Mediterranean Sea and eastern Arabian Sea. It was first identified by Carl Linnaeus in 1758, under the basionym Medusa porpita. In addition, it is one of the two genera under the suborder Chondrophora, which is a group of cnidarians that also includes Velella. The chondrophores are similar to the better-known siphonophores, which includes the Portuguese man o' war, or Physalia physalis. Although it is superficially similar to a jellyfish, each apparent individual is actually a colony of hydrozoan polyps. The taxonomic class, Hydrozoa, falls under the phylum Cnidaria, which includes anemones, corals, and jellyfish, which explains their similar appearances.
Janthina exigua, also known as the dwarf janthina, is a species of small holoplanktonic sea snail, a marine gastropod mollusk in the family Epitoniidae, the violet snails or purple storm snails.
Janthina umbilicata, also known as the elongate janthina, is a species of holoplanktonic sea snail, a marine gastropod mollusk in the family Epitoniidae, the violet snails or purple storm snails.
Janthina pallida, also known as the pale janthina, is a species of holoplanktonic sea snail, a marine gastropod mollusk in the family Epitoniidae, the violet snails or purple storm snails.
Akera bullata, named the royal flush sea slug, is a species of sea snail, a marine opisthobranch gastropod mollusk in the family Akeridae, a family that is related to the sea hares. This species is the only European representative of the genus Akera.
Splendrillia globosa is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.
Hemifusus is a genus of sea snails, marine gastropod molluscs in the family Melongenidae, the crown conches and their allies.
Recluzia is a genus of small to medium-sized pelagic or planktonic sea snails, marine gastropod molluscs in the family Epitoniidae.
The taxonomy of the cone snails and their allies as proposed by John K. Tucker and Manuel J. Tenorio in 2009 was a biological classification system for a large group of predatory sea snails. This system was an attempt to make taxonomic sense of the large and diverse group which contains the family Conidae, the cone snails. The authors proposed extensive changes to the family Conidae in contrast to the way the group was treated in the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005. Bouchet and Rocroi included in the family Conidae several other groups of toxoglossan snails which had previously been placed in the Turridae.
Pila globosa is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Ampullariidae, the apple snails.
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.
