WitrynaNematodes comprise many free-living and parasitic species; some are important parasites in man as well as wild and farmed animals including fish, and in agriculture. … The development of distinct tagmata is believed to be a feature of the evolution of segmented animals, especially arthropods. In the ancestral arthropod, the body was made up of repeated segments, each with similar internal organs and appendages. One evolutionary trend is the grouping together of some segments into larger units, the tagmata. The evolutionary process of grouping is called t…
