Bornellidae is a family of nudibranch sea slug - marine gastropod molluscs in the superfamily Tritonioidea.
This family is within the clade Cladobranchia (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
Nudibranch species within the Bornellidae family have elongated bodies, with pairs of cerata-like dorsal and lateral appendages, with finger-like branches, running along the length of the body. Each of these appendages has an attached cluster of gills. Their rounded head has a tentacle on either side of the mouth, with tiny finger-like papillae. The rhinophores on the head resemble the dorsal appendages.
Nudibranchs within this family are believed to feed exclusively on hydroids.
Nudibranchs are a group of soft-bodied marine gastropod molluscs that shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", "dragon", and "sea rabbit". Currently, about 3,000 valid species of nudibranchs are known.
Sea angels are a large group of small free-swimming sea slugs, not to be confused with Cnidarians, classified into six different families. They are pelagic opisthobranchs in the clade Gymnosomata within the larger mollusc clade Heterobranchia. Sea angels were previously referred to as a type of pteropod.
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are gastropods, i.e. they are sea snails that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells.
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.

Bassipterus is a genus of eurypterid, an extinct group of aquatic arthropods. Bassipterus is classified as part of the family Adelophthalmidae, the only clade within the derived ("advanced") Adelophthalmoidea superfamily of eurypterids. Fossils of the single and type species, B. virgnicus, have been discovered in deposits of the Late Silurian age in West Virginia and Maryland, United States. The genus is named after Bass, where most of the fossils have been recovered.
Radiodonta is an extinct order of stem-group arthropods that was successful worldwide during the Cambrian period. They may be referred to as radiodonts, radiodontans, radiodontids, anomalocarids, or anomalocaridids, although the last two originally refer to the family Anomalocarididae, which previously included all species of this order but is now restricted to only a few species. Radiodonts are distinguished by their distinctive frontal appendages, which are morphologically diverse and used for a variety of functions. Radiodonts included the earliest large predators known, but they also included sediment sifters and filter feeders. Some of the most famous species of radiodonts are the Cambrian taxa Anomalocaris canadensis, Hurdia victoria, Peytoia nathorsti, Titanokorys gainessii, Cambroraster falcatus and Amplectobelua symbrachiata, the Ordovician Aegirocassis benmoulai and the Devonian Schinderhannes bartelsi.
The Butler's frogfish or blackspot anglerfish, Tathicarpus butleri, is a rare species of frogfish in the family Antennariidae. The only member of its genus, this species is the most derived member of its family and represents a separate lineage from all other frogfishes, leading to some consideration of it being placed in its own family. It is found off the southern coast of New Guinea, and along the coasts of Western Australia to 33° S latitude, the Northern Territory, and Queensland to 22° S latitude. A benthic species, it inhabits inshore tropical waters and coral reefs to a maximum depth of 145 m (476 ft), though most are found shallower than 45 m (148 ft). Its specific epithet is after its discoverer Dr. Graham Butler.
Bornella is a genus of sea slugs, specifically dendronotid nudibranchs in the family Bornellidae.
The Cladobranchia are a taxonomic clade of nudibranchs, sea slugs, marine gastropod molluscs in the clade Dexiarchia.
Plocamopherus maculapodium is a species of sea slug, a nudibranch, a shell-less marine gastropod mollusk in the family Polyceridae.
Plocamopherus pecoso is a species of sea slug, a nudibranch, a shell-less marine gastropod mollusk in the family Polyceridae.
Kaloplocamus dokte is a species of sea slug, a nudibranch, a shell-less marine gastropod mollusk in the family Polyceridae.
Dendronotus kalikal is a species of sea slug, a dendronotid nudibranch, a shell-less marine gastropod mollusc in the family Dendronotidae.
Dendronotus kamchaticus is a species of sea slug, a dendronotid nudibranch, a shell-less marine gastropod mollusc in the family Dendronotidae.
Dendronotus niveus is a species of sea slug, a dendronotid nudibranch, a shell-less marine gastropod mollusc in the family Dendronotidae.
Cabangus regius is a species of sea slug, a dendronotid nudibranch, a shell-less marine gastropod mollusc in the family Dendronotidae.
Bornella irvingi is a species of sea slug, a nudibranch, a shell-less marine gastropod mollusc in the family Bornellidae.
Dvulikiaspis is a genus of chasmataspidid, a group of extinct aquatic arthropods. Fossils of the single and type species, D. menneri, have been discovered in deposits of the Early Devonian period in the Krasnoyarsk Krai, Siberia, Russia. The name of the genus is composed by the Russian word двуликий (dvulikij), meaning "two-faced", and the Ancient Greek word ἀσπίς (aspis), meaning "shield". The species name honors the discoverer of the holotype of Dvulikiaspis, Vladimir Vasilyevich Menner.
Bornella pele is a species of nudibranch in the family Bornellidae. It is found in waters off Hawaiʻi, Australia, Japan, French Polynesia, and Réunion. The species epithet derives from Pele, the Hawaiian god of volcanoes, due to the nudibranch's red markings.
