Nematode An Entity of Type: EukaryoticCellfrom Named Graph: Bislang wurden mehr als Se conocen vulgarmente como gusanos redondos debido a la forma de su cuerpo en un corte transversal.

Il est commode de les classer selon leur mode de transmission. Folo Nematodi, al contrario dei Platelminti, presentano un vero e proprio tubo digerente dotato di bocca e ano. Er zijn meer dan Ook de aaltjes behoren tot de nematoden.

Nematologie is de wetenschap die de nematoden bestudeert. Veel nematoden leven in de bodem van dode organische stof.

Andere mematelmintos leven als parasiet en veroorzaken plantenziekten zoals aardappelmoeheid of zitten in het darmkanaal van zoogdieren zoals de spoelwormen of de aarswormpjes en worden in het laatste geval dan vaak als draadworm aangeduid. Sommige nematoden kunnen ne,atelmintos 8 meter lang worden, maar de meeste nematoden zijn voor het blote oog onzichtbaar. Ze zijn dan hooguit 1 mm lang en zeer smal. Ze komen overal voor.

Aaltjes worden ook toegepast als natuurlijke vijanden van plaaginsecten of naaktslakken. De soort Caenorhabditis elegans wordt gebruikt als modelorganisme. Het was de eerste meercellige eukaryoot waarvan het genoom volledig in kaart werd gebracht.

Lista de filos de animais

Eram classificados, juntamente com outros grupos, no filo Nemathelminthes nematelmintoshoje obsoleto. They are a diverse animal phylum inhabiting a very broad range of environments.

Nematode species can be difficult to distinguish, and although over 25, have been described, of which more than half are parasitic, the total number of nematode species has been estimated to be about 1 million. Unlike the phyla Cnidarians and Platyhelminthes flatwormsnematodes have nematelmkntos digestive systems with openings at both ends.

Nematodes have successfully adapted to nearly every ecosystem from marine salt water to fresh water, to soils, and from the polar regions to the tropics, as well as the highest to the lowest of elevations. They are ubiquitous in freshwater, marine, and terrestrial environments, where they often outnumber other animals in both individual and species counts, and are found in locations as diverse as mountains, deserts and oceanic trenches. They are found in every part of the earth’s lithosphere, even at great depth 0.

The many parasitic forms include pathogens in most plants and animals including humans. Some nematodes can undergo cryptobiosis. Nathan Cobb, a nematologist, described the ubiquity of nematodes on Earth thus: In short, if all the matter in the universe except the nematodes were swept away, our world would still be dimly recognizable, and if, as disembodied spirits, we could then investigate it, we should find its mountains, hills, vales, rivers, lakes, and oceans represented by a film of nematodes.

The location of towns would be decipherable, since for every massing of human beings there would be a corresponding massing of certain nematodes. Trees would still stand in ghostly rows representing our streets and highways.

The location of the various plants and animals would still be decipherable, and, had we sufficient knowledge, in many cases even their species could be determined by an examination of their erstwhile nematode parasites. Caenorhabditis elegans, a model species of roundworm.
