What is the difference between Lophotrochozoans, Edcysozoans and Platyzoans?

There are two primary groups of bilaterian (bilaterally symmetrical) animals: schedules and deuterostomes. They are also called Superfyl, because each contains more animal phyles. Deuterostomes tend to be more complicated and include echinoderms, hemichordates, chords (all vertebrates) and several smaller phyla. Protostomes contain virtually everything else, including arthropods, annelids, flat worms, molluscs, etc. Several small phyles are not classified as. The primary difference between the two groups is how they evolve as an embryos: in the protosities the first opening in the embryo becomes the mouth and in deuterostomes becomes the rectum.

Most scientists recognize at least three superfyles in the schedules - Lophotrochozoa, Edcysozoa and Platyzoa. These superfys were designed in 1995, 1997 and 1998, based on molecular and morphological evidence. Lophotrochozoans ("Animals bearing ridges") are connected by the presence ofophore, the ring of the ciliated tentacle around their mouths, used to grasp particlesfood. Lophotrochozoans, sometimes also called trozozoans, include about a dozen phyles: ENPROCTA, MOLLUSCA, Annelida, Phoronide, Brachiopod, Nemertera, Chaetognatha, Bryozoa, Myzostomid, Acoel and Gnathostomulid. Most of the charm is sea, which makes sense, because the mouth for grabbing food is the most useful underwater.

6 Platyzoans are distinguished either by the absence of coeloma (body cavity) or reduced coeloma called pseudocoel. Platyzoa is on average the simplest of the Support Superfyll, although simple organisms are located between Lophotrochozoans. Platyzoans were previously considered members of Lophotrochozoa, but most scientists now give them their own group.

The latest Superfyl is ecdysozoa, marked by melting their exoskeletons (eCDY). EcDysozoa is the most successful and most widespread of the Superfyll of Protostome and includes arthropods (crustaceans, insects,Chelerates and Myriapodes), Nematodes (Roungorms), Tardigrady, Velvet worms and several smaller phyla. Nematodes are one of the largest animals on Earth that is found in every conceivable environment, including Antarctica, while arthropods contain most species, probably more than 7 million, which represents more than 90% of all biodiversity on Earth. Although there are many other organisms that use some form of shell or external cuticle, EcDysozoa is obviously the most evolutionary effective.
