Nominal species treated as members of the genus include:

The type species is Nuclearia delicatula, which may adopt a spherical or a flattened body form.

There is considerable uncertainty as to the identity of species and genera, and this led to the inclusion in Nuclearia of taxa previously assigned to Astrodisculus, Nuclearella, Nuclearina, Heliosphaerium and Nucleosphaerium, and the diversity rendered to 9 clearly distinguishable species with the affinities of Astrodisculus araneiformis, A. minuta and A. marinus remaining unclear [6]

<span class="mw-page-title-main">Nucleariida</span> Order of amoebae

Nucleariida is a group of amoebae with filose pseudopods, known mostly from soils and freshwater. They are distinguished from the superficially similar vampyrellids mainly by having mitochondria with discoid cristae, in the absence of superficial granules, and in the way they consume food.

<span class="mw-page-title-main">Vampyrellidae</span> Family of single-celled organisms

The family Vampyrellidae is a subgroup of the order Vampyrellida within the supergroup Rhizaria. Based on molecular sequence data, the family currently comprises the genus Vampyrella, and maybe several other vampyrellid amoebae. The cells are naked and characterised by radiating, filose pseudopodia and an orange colouration of the main cell body.

<span class="mw-page-title-main">Centrohelid</span> Group of algae

The centrohelids or centroheliozoa are a large group of heliozoan protists. They include both mobile and sessile forms, found in freshwater and marine environments, especially at some depth.

<i>Crassispira</i> Genus of gastropods

Crassispira is a genus of small predatory sea snails with narrow, high-spired shells, marine gastropod mollusks in the family Pseudomelatomidae. They first appeared in the fossil record approximately 48.6 million years ago during the Eocene epoch, and still exist in the present day.

<i>Natica</i> Genus of gastropods

Natica is a genus of small to medium-sized predatory sea snails, marine gastropods in the subfamily Naticinae of the family Naticidae, the moon snails. The genus was erected by Giovanni Antonio Scopoli in 1777.

<i>Fusinus</i> Genus of gastropods

Fusinus is a genus of small to large sea snails, marine gastropod mollusks in the family Fasciolariidae, the spindle snails and tulip snails.

<i>Mangelia</i> Genus of gastropods

Mangelia is a large genus of sea snails, marine gastropod mollusks in the family Mangeliidae.

<span class="mw-page-title-main">Vampyrellida</span> Order of single-celled organisms

The vampyrellids, colloquially known as vampire amoebae, are a group of free-living predatory amoebae classified as part of the lineage Endomyxa. They are distinguished from other groups of amoebae by their irregular cell shape with propensity to fuse and split like plasmodial organisms, and their life cycle with a digestive cyst stage that digests the gathered food. They appear worldwide in marine, brackish, freshwater and soil habitats. They are important predators of an enormous variety of microscopic organisms, from algae to fungi and animals. They are also known as aconchulinid amoebae.

<span class="mw-page-title-main">Taxonomy of Protista</span> Classification of eukaryotes

A protist is any eukaryotic organism that is not an animal, plant, or fungus. The protists do not form a natural group, or clade, since they exclude certain eukaryotes with whom they share a common ancestor; but, like algae or invertebrates, the grouping is used for convenience. In some systems of biological classification, such as the popular five-kingdom scheme proposed by Robert Whittaker in 1969, the protists make up a kingdom called Protista, composed of "organisms which are unicellular or unicellular-colonial and which form no tissues". In the 21st century, the classification shifted toward a two-kingdom system of protists: Chromista and Protozoa.
