Summary
[edit]DescriptionAerjalgne.jpg |
Eesti: Aerjalalised on veeloomad nagu enamik vähke. Neid elab massiliselt nii mere- kui magevee kõigis sügavustes, samuti lompides, rabalaugastes ning mõned liigid niiskes samblas ja kõdus. Nende hulgas on ka parasiite, kelle välimus võib olla tundmatuseni muutunud ning kes elutsevad kaladel ja teistel veeloomadel. Vabaltelavad aerjalalised on kõigest mõne millimeetri pikkused (0,5-2mm) ja etendavad tähtsat osa veekogu toiduahelas : nad paljunevad suhteliselt kiiresti, ning toitudes pisikestest mikroskoopilistest organismidest on nad ise pidevalt toiduks suurematele veeloomadele.
Maailmas tuntakse umbes 8500 aerjalaliste liiki, Eestis on neid viimastel andmetel teada 82, oletatakse aga 100 liigi olemasolu.
English: Copepods are aquatic animals like most crustaceans. They live en masse in all depths of both sea and fresh water, as well as in puddles, swamps, and some species in moist moss and wasteland. Among them are also parasites whose appearance can be changed beyond recognition and which live on fish and other aquatic animals. Free-living copepods are only a few millimeters long (0,5-2mm) and play an important part in the water body's food chain: they reproduce relatively quickly, and by feeding on tiny microscopic organisms, they themselves are constantly food for larger aquatic animals. Around 8,500 species of copepods are known in the world, according to the latest data, 82 are known in Estonia, but the existence of 100 species is assumed. |
