Exempel på hur man kan använda PLANARIANS i en mening

• Planarians (triclads) are free-living flatworms of the class Turbellaria, Their body is populated by adult stem cells called neoblasts, which planarians use for regenerating missing body parts.
• Amphipods and planarians exist under rocks, along with various algaes, chitons, and some gastropods.
• The planarians retained this acquired information after being sliced and regenerated, even after multiple slicings to produce a planarian where none of the original trained planarian was present.
• It is associated with other cave organisms, including the isopod Caecidotea recurvata, the amphipod Crangonyx antennatus, snails (genus Fontigens), and planarians (genus Sphalloplana).
• As part of the soil ecosystem, land planarians feed mainly on other invertebrates, such as earthworms, snails, slugs, nemerteans, velvet worms, woodlice, millipedes, insects and arachnids.
• published both satirical articles, such as "A Stress Analysis of a Strapless Evening Gown", and scientific papers, the most famous of which, "Memory transfer through cannibalism in planarians", was a result of McConnell's RNA memory transfer experiments with planarian worms and was later published in the Journal of Neuropsychiatry.
• The genus Bipalium was initially defined by Stimpson to include land planarians with the head broadened, forming a head plate.
• Continenticola is a clade that includes the land planarians (Geoplanidae) and the freshwater triclads (Dendrocoelidae, Dugesiidae, Kenkiidae and Planariidae).
• In Dugesiidae, the oviducts, which conduct the eggs from the ovaries to the genital atrium, open into the bursal canal, while in other freshwater planarians they open directly into the genital atrium.
• The subfamily Microplaninae was defined by Ogren and Kawakatsu (1988) for land planarians with a short and cylindroid form, an anterior end that is blunt, eyes often small and subepithelial musculature weak.
• These included terrestrial flatworms (planarians) and nemerteans, but the most famous of his animals was the so-called "living fossil" Peripatus.
• The subfamily Geoplaninae was initially defined by Ogren and Kawakatsu (1990) for land planarians which have a broad creeping sole, mouth in the second half of the body, dorsal testes, subepithelial longitudinal musculature well developed and parenchymal longitudinal musculature absent or not well developed.
• In the following decades, several authors, such as Albert Riester and Ernst Marcus, continued to identify most Brazilian yellow planarians with 5 or 7 dark longitudinal stripes as Geoplana marginata.
• Among the phenomena he investigated were nerve compression, plasmolysis in cartilage cells, the electrical conductivity of plasma during coagulation, intestinal respiration in Misgurnus fossilis, respiration in certain gastropod genera (Limax, Helix, Planorbis, Lymnaea), functional particularities of the silk glands of the silkworm and the effect of light upon planarians.
• The genus Geoplana was erected in 1857 by William Stimpson and included most land planarians with several eyes distributed along the body.
• Bolaños has continued her research and is working on comparisons between polyclads, planarians and other types of platyhelminths and their abilities to regenerate.
• The tribe Rhynchodemini is defined as containing land planarians with an elongate, cylindroid form, two eyes near the anterior end and strong subepithelial musculature in which the longitudinal fibers are grouped into large bundles.
• The tribe Anzoplanini contains land planarians with dorsoventral testes, a condition that in land planarians is considered intermediate between a primitive ventral condition and a derivate dorsal condition.
• The name Difroehlichia honors the planarian researchers Claudio Gilberto Froehlich and Eudóxia Maria Froehlich, who made important contributions to the knowledge of Brazilian land planarians.
• It was discovered by inspecting the transcriptomes of the planarian flatworm Schmidtea mediterranea and is the first known RNA virus infecting planarians.
