Triloculina
''Triloculina'' is a genus of foraminifera in the order Miliolida, included in the Quinqueloculininae. The test is three, chambers each a half coil in length. Early chambers, at least in the microspheric generation, in quinqueloculinan arrangement, later becoming triloculine with successive chambers added in planes 120 degrees apart. Only the final three chambers are visible externally. The aperture is terminal, at the end of the final chamber, with a bifid tooth in adult forms. As with the entire order, the test is composed of imperforate, porcelaneous calcite. The Pliocene to Recent '' Cruciloculina'' is very similar, except for having a different aperture, and is a likely derivative. References * Joseph A.

Sigmoilopsis
''Sigmoilinopsis'' is a genus of miliolid Foraminifera, with an ovate test, chambers one-half coil in length, arranged in rapidly changing planes in the early stage resulting in two spiralling series that appear sigmoid in section, gradually becoming planispiral in the adult. Walls are thick, porcelaneous but enclosing a large quantity of agglutinated quartz particles, sponge spicules, and shell fragments; the aperture terminal, rounded, with a small tooth. ''Sigmoilinopsis'' is grossly similar to '' Sigmoilina'' but with less enveloping chambers allowing earlier ones to be externally visible, and in incorporating agglutinated material. ''Sigmoilinopsis'' is included in the Hauerinidae ( Loeblich & Tappan 1988). Previously it was assigned to the Miliolidae ''Miliolidae'' is a family in the superfamily ''Miliolacea'' of miliolid foraminifera Foraminifera (; Latin for "hole bearers"; informally called "forams") are single-celled organisms, members of a phylum or class of ...

Cruciloculina
''Cruciloculina'' is a genus of foraminifers included in the Miliolidae from the Neogene, closely resembling ''Triloculina'' The test is free, chambers one-half coil in length, added in planes 120 deg. apart, as in ''Triloculina''. Tests are rounded to triangular in section; sutures depressed. As with other miliolid, the wall of the test is composed in imperforate, porcelaneous calcite. The aperture is terminal, at the end of the final chamber, but instead of having a distinct tooth, as in ''Triloculina'', ''Cruciloculina'' develops as tri-radiate aperture in the young that becomes cruciform (X-shaped) to dendritic in the adult. Derivation from ''Triloculina'' is apparent. ''Cruciloculina'' is known from the North Atlantic and South Atlantic Oceans and from Japan. Recent species have been found, for example, near the Falkland and South Georgia Islands. References * Alfred R.

Quinqueloculina
''Quinqueloculina'' is a genus of foraminifera in the family Miliolidae. As with all miliolids the test of ''Quinqueloculina'' is composed of imperforate, porcelaneous calcite, often giving them a yellowish tint. As with the Miliolidae, the chambers are arranged in various planes, with two chambers per whorl. In ''Quinqueloculins'' the chambers are in planes set 72 degrees apart, but successive chambers are in planes separated by 144 degrees. The name ''Quinqueloculina'' comes from ''quinque'', the Latin for five. In ''Quinqueloculina'' five chambers are exposed to view on the outside, although the earlier three are sandwiched between the later two, one on one side, two on the other. Chambers are generally long and tubular, normally without integral floors, that function made by the underlying chamber. Some 30 or more species of ''Quinqueloculina'' have been named. ''Quinqueloculina'' is found in abundance around the coasts of the UK. High concentrations of one species of ''Qu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eukaryota
Eukaryotes () are organisms whose cells have a nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard archaea. This implies that there are only two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.3–1.8 billion years ago, during the Proterozoic eon, likely as Flagellated cell, flagellated phagotrophs. Their name comes from the Greek language, Greek wikt:εὖ, εὖ (''eu'', "well" or "good") and wikt:� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siphonaptera (genus)
Flea, the common name for the order Siphonaptera, includes 2,500 species of small flightless insects that live as external parasites of mammals and birds. Fleas live by ingesting the blood of their hosts. Adult fleas grow to about long, are usually brown, and have bodies that are "flattened" sideways or narrow, enabling them to move through their hosts' fur or feathers. They lack wings; their hind legs are extremely well adapted for jumping. Their claws keep them from being dislodged, and their mouthparts are adapted for piercing skin and sucking blood. They can leap 50 times their body length, a feat second only to jumps made by another group of insects, the superfamily of froghoppers. Flea larvae are worm-like, with no limbs; they have chewing mouthparts and feed on organic debris left on their hosts' skin. Genetic evidence indicates that fleas are a specialised lineage of parasitic scorpionflies (Mecoptera) ''sensu lato'', most closely related to the family Nannochor ...

Sigmoilina
''Sigmoilina'' is a miliolid genus, referring to the foraminiferal order Miliolida, characterized by an assymmetricall biconvex test formed by strongly overlapping chambers, one-half coil in length, that form a sigmoid (S-shaped) curve in cross section. The strongly overlapping chambers obliterate earlier ones from view resulting in the compressed biloculine appearance, differing from the squat, depressed biloculine form of '' Pyrgo'' and '' Biloculina''. The test, as for all Miliolida, is porcelaneous and imperphorate, the terminal aperture, with tooth, the only point of egress and ingress for the animal. ''Sigmoilina'' is a protist, or proctoctist according to B.K. Sen Gupta, 1999, included in the miliolid family Hauerinidae ( Loeblich & Tappan, 1988). It was previously assigned to the Miliolidae ''Miliolidae'' is a family in the superfamily ''Miliolacea'' of miliolid foraminifera Foraminifera (; Latin for "hole bearers"; informally called "forams") are single-cell ...
