The seaducks (Mergini) are a tribe of the duck subfamily of birds, the Anatinae. The taxonomy of this group is incomplete. Some authorities separate the group as a subfamily, others remove some genera from the group and keep others. Most species within the group spend their winters near coastal waters. Many species have developed specialized salt glands to allow them to tolerate salt water but these are poorly developed in juveniles. Some of the species prefer riverine habitats. All but two of the 20 species in this group live in far northern latitudes.
Balaenoptera, from the Latin balaena (whale) and Ancient Greek pteron (fin), is a genus of Balaenopteridae, the rorquals, and contains eight extant species. The species Balaenoptera omurai was published in 2003. Balaenoptera is a diverse genus and comprises all but one of the extant species in its family - the other species is the humpback whale, Megaptera novaeangliae.
Murex is a genus of medium to large sized predatory tropical sea snails. These are carnivorous marine gastropod molluscs in the family Muricidae, commonly called "murexes" or "rock snails".
Moray eels, or Muraenidae, are a family of eels whose members are found worldwide. There are approximately 200 species in 15 genera which are almost exclusively marine, but several species are regularly seen in brackish water, and a few are found in fresh water.
A salp or salpa is a barrel-shaped, planktonic tunicate. It moves by contracting, thus pumping water through its gelatinous body, one of the most efficient examples of jet propulsion in the animal kingdom. The salp strains the pumped water through its internal feeding filters, feeding on phytoplankton.
Tube-dwelling anemones or ceriantharians look very similar to sea anemones but belong to an entirely different subclass of anthozoans. They are solitary, living buried in soft sediments. Tube anemones live inside and can withdraw into tubes, which are composed of a fibrous material made from secreted mucus and threads of nematocyst-like organelles known as ptychocysts. Ceriantharians were formerly classified in the taxon Ceriantipatharia along with the black corals but have since been moved to their own subclass, Ceriantharia.
The Trochidae, common name top-snails or top-shells, are a taxonomic family of very small to large sea snails, marine gastropod molluscs in the clade Vetigastropoda.
Neritidae, common name the nerites, is a taxonomic family of small- to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum.
Corallimorpharia is an order of marine cnidarians closely related to stony or reef building corals (Scleractinia). They are mostly tropical, with a narrow column topped with a wide oral disc. The tentacles are usually short or very short, arranged in rows radiating from the mouth. Many species occur together in large groups. In many respects, they resemble the stony corals, except for the absence of a stony skeleton.
Rhytidocystis is a genus of apicomplexans. It is the only genus within the monotypic family Rhytidocystidae. The species of this genus are parasitic protozoa found in marine annelids.
Mesodinium chamaeleon is a ciliate of the genus Mesodinium. It is known for being able to consume and maintain algae endosymbiotically for days before digesting the algae. It has the ability to eat red and green algae, and afterwards using the chlorophyll granules from the algae to generate energy, turning itself from being a heterotroph into an autotroph. The species was discovered in January 2012 outside the coast of Nivå, Denmark by professor Øjvind Moestrup.
Veloxidium is a genus of parasitic alveolates in the phylum Apicomplexa. Species in this genus infect marine invertebrates.
The Platyproteum are a genus of parasitic alveolates in the phylum Apicomplexa. Species in this genus infect marine invertebrates.
Siedleckia are a genus of parasitic alveolates in the phylum Apicomplexa. Species in this genus infect marine invertebrates.
John Ernest "Jack" Randall is an American ichthyologist and a leading authority on coral reef fishes. Randall has described over 600 species and has authored 11 books and over 670 scientific papers and popular articles. He has spent most of his career working in Hawaii.
Corallimorphus niwa is a species of corals in the genus Corallimorphus. It was classified by Fautin in 2011. Corallimorphus niwa lives in marine habitats.
Corallimorphus profundus is a species of corals in the genus Corallimorphus. It lives in marine habitats. This species can be found in the Southern Ocean and in New Zealand.
The Interim Register of Marine and Nonmarine Genera (IRMNG) is a taxonomic database containing the scientific names of the genus, species, and higher ranks of many plants, animals and other kingdoms, both living and extinct, within a standardized taxonomic hierarchy, with associated machine-readable information on habitat and extant/fossil status for the majority of entries. The database aspires to provide complete coverage of both accepted and unaccepted genus names across all kingdoms, with a subset only of species names included as a lower priority. In its March 2019 release, IRMNG contained 490,095 genus names, of which 236,514 were listed as "accepted", 120,194 "unaccepted", 7,391 of "other" status i.e. interim unpublished, nomen dubium, nomen nudum, taxon inquirendum or temporary name, and 125,996 as "uncertain". The data originate from a range of print, online and database sources, and are reorganised into a common data structure to support a variety of online queries, generation of individual taxon pages, and bulk data supply to other biodiversity informatics projects. IRMNG content can be queried and displayed freely via the web, and download files of the data down to the taxonomic rank of genus as at specific dates are available in the Darwin Core Archive (DwC-A) format. The data include homonyms, including both available and selected unavailable names.
