Most references to " amoebas " or " amoebae " are to amoeboids in general rather than to the specific genus Amoeba.

See: Table of cell sizes — Dense populations of a giant sulfur bacterium in Namibian shelf sediments — Large protists of the genus Chaos, closely related to the genus Amoeba

Members of the genus closely resemble Amoeba, and share the same general morphology, producing numerous cylindrical pseudopods, each of which is rounded at the tip.

The species is now placed in the independent genus Chaos, a sister group of Amoeba.

However, the same research raises questions about the monophyly of the genus Chaos, since Chaos nobile may be basal to a group containing Chaos carolinensis and at least two species of Amoeba

The following year, Cavalier-Smith included the genus with several other " primitive " amitochondriate amoeboids in a new taxonomical group: the Archamoebae.

Gromia is a widespread genus of marine and freshwater amoeboids, closely resembling some foraminiferans.

So we ask what the genus, or general category, of the species is ; the Greeks ( but not the biologists ) would say that the genus is animal.

The greatest innovation of Linnaeus, and still the most important aspect of this system, is the general use of binomial nomenclature, the combination of a genus name and a second term, which together uniquely identify each species of organism.

In essential structural characteristics, as well as in general appearance and habits, all the animals of this genus very closely resemble each other, so whether they should be considered as belonging to one, two, or more species is a matter of controversy among naturalists.

In general, identification to genus can often be accomplished in the field using a local mushroom guide.

* Is existence a genus or general class that is simply divided up by specific differences?

In rare cases, this abbreviated form has spread to more general use ; for example, the bacterium Escherichia coli is often referred to as just E. coli, and Tyrannosaurus rex is perhaps even better known simply as T. rex, these two both often appearing in this form in popular writing even where the full genus name has not already been given.

In general, Magnolia is a genus which has attracted a lot of horticultural interest.

A general consensus exists as to the designation of high, middle, and low families, the makeup of the basic canon of ten cloud genera that results from this cross-classification, and the family affiliation of non-vertical genus types.

* Comma butterfly, the brush-footed butterfly Polygonia c-album ( and related species ; " comma butterflies ": the genus Polygonia in general )

* Informal name for species in the Velociraptor genus of dinosaurs, or members of the family Dromaeosauridae in general

However, the genus did not receive general recognition until 1947 when it was revived by E. E. Cheesman in the first of a series of papers in the Kew Bulletin on the classification of the bananas, with a total of 25 species.

Gentile derives from Latin gens ( from which, together with forms of the cognate Greek word genos, also derive gene, general, genus and genesis ).

The origin of the genus appears to be in the general area of Eastern Siberia / Mongolia.

The general characteristics for this genus are: single-noded pseudobulbs, the basal inflorescence and the mobile lip.

The taxonomy of the swifts is in general complicated, with genus and species boundaries widely disputed, especially amongst the swiftlets.

The close Speckled-GWT relationship suggested by mtDNA data could of course still apply to the taxa in general, not just to sequences in 2 maternally inherited genes in a few individual ducks ( for which it without doubt does apply ), but the overall failure of Johnson & Sorenson to seriously take hybridization into account and their small sample sizes and obsolete conceptions of Indian Ocean biogeography do not help at all to resolve the issue, but in 1999, the methodology and interpretation were reasonable enough and in fact, the study was pioneering in many respects due to dense taxon-level sampling and still represents one of the default references for interpreting the pyhlogeny of the genus.

On a general Riemann surface of genus g, K has degree 2g − 2, independently of the meromorphic form chosen to represent the divisor.

This general term does not mean that the subject is a member of class Bacilli or genus Bacillus.

Pittas are all similar in general structure and habits, and have often been placed in a single genus, although as of 2009 they are now split into three genera, Pitta, Erythropitta and Hydrornis.

Daylily is the general nonscientific name of a species, hybrid or cultivar of the genus Hemerocallis ().

The  genus is a rational number defined for any manifold, but is in general not an integer.

These are the most general features of the genus and can be considered distinguishing characteristics.

At the time both South African and South American plants were placed in the same genus ; subsequently they were separated into two different genera.

However, the tree constructed by the living tree project, a collaboration between ARB-Silva and LPSN where a 16S ( and 23S if available ) tree of all validated species was constructed, the genus Bacillus contains a very large number of nested taxa and majorly in both 16S and 23S it is paraphyletic to Lactobacillales ( Lactobacillus, Streptococcus, Staphylococcus, Listeria, etc.

Colloquially, the common chimpanzee is often called the chimpanzee ( or " chimp "), though technically this term refers to both species in the genus Pan: the common chimpanzee and the closely related bonobo, formerly called the pygmy chimpanzee.

Thus, a ' square ' is a member of both the genus ' rectangle ' and the genus ' rhombus '.

H. floresiensis is intriguing both for its size and its age, being an example of a recent species of the genus Homo that exhibits derived traits not shared with modern humans.

As reported in the journal Science, testing of mitochondrial and nuclear DNA by Warren Johnson and Stephen O ' Brien of the U. S. National Cancer Institute demonstrated that ancient cats evolved into eight main lineages that diverged in the course of at least 10 migrations ( in both directions ) from continent to continent via the Bering land bridge and Isthmus of Panama, with the Panthera genus being the oldest and the Felis genus being the youngest.

In fact, the definition of a square may be recast in terms of both of the abstractions, where one acts as the genus and the other acts as the differentia:

The name of the plant family Proteaceae as well as the genus Protea, both to which P. cynaroides belongs to, derive from the name of the Greek god Proteus, a deity that was able to change between many forms.

This is an appropriate image, seeing as both the family and the genus are known for their astonishing variety and diversity of flowers and leaves.

Ingredients common to both sides include chili peppers ( the genus Capsicum ), maize, beans, tomatoes, tortillas, and beef ( both areas have a strong tradition of cattle ranching ).

Up until the last half-decade, the majority of the scientific community included all the species of both Australopithecus and Paranthropus in a single genus.

In 1912 he gave an algorithm that solves both the word and conjugacy problem for the fundamental groups of closed orientable two-dimensional manifolds of genus greater than or equal to 2,.

Besides the urban cycle there is, both in Africa and South America, a sylvatic cycle ( Forest cycle or Jungle cycle ), where Aedes africanus ( in Africa ) or mosquitoes of the genus Haemagogus and Sabethes ( in South America ) serve as a vector.

( The name wild rice is usually used for species of the grass genus Zizania, both wild and domesticated, although the term may also be used for primitive or uncultivated varieties of Oryza.

Salmon live along the coasts of both the North Atlantic ( the migratory species Salmo salar ) and Pacific Oceans ( half a dozen species of the genus Oncorhynchus ), and have also been introduced into the Great Lakes of North America.

This structure is similar to the dengue fever virus ; both belong to the genus Flaviviruswithin the family Flaviviridae.

" As time passed, Anning's confidence in her knowledge grew, and in 1839 she wrote to the Magazine of Natural History to question the claim made in an article, that a recently discovered fossil of the prehistoric shark Hybodus represented a new genus, as an error since she had discovered the existence of fossil sharks with both straight and hooked teeth many years ago.

When the original name is changed, e. g. the species is moved to a different genus, both Codes use parentheses around the original authority ; the ICN also requires the person who made the change to be given.

Around 1840 – 41, German meteorologist Ludwig Kaemtz added stratocumulus as a mostly detached low-cloud genus of limited convection with both cumuliform and stratiform characteristics similar to upper-level cirrocumulus.

The genus also includes numerous hybrids, both natural and bred by man, such as the loganberry ( Rubus × loganobaccus ).
