Here we have made an attempt to make a comparative study between schiphozoa , nematoda and pollinators along with Gastropoda , Medusa and Ecdysone . `Phyla ' is the equivalent of the word division in Botany and refers to the class of multicellular animals devoid of cellulose cell walls and resources required for photosynthesis . There are about 35 classes of animal phyla which exist today , most of them being invertebrates . The animal phyla are divided according to the nature of the coelom and symmetry

Schiphozoa , Nematoda and Pollinators

One of the oldest

types of phyla , without a coelom is the Cnidaria . The Cnidaria phylum boasts of about 10 ,000 types of animal species . A major part of the underwater world belongs to this category . The Cnidaria is further subdivided into Hydrozoa , Schiphozoa or Scyphozoa and Anthozoa The gastrovascular cavity controls their digestive mechanism . A typical example of the Schiphozoa Cnidaria phylum is the jellyfish or the Medusa . These types of animal phyla are carnivores and move slowly by compressing their flattened and bell-shaped body structure

Apart from the Schiphozoa Cnidaria phylum , the Nematoda is another major category of the animal phyla . They are commonly found in plants animals , water and soil . A common example of the Nematoda is roundworms which mostly live on plant , soil , water and animals . Like the Schiphozoa Cnidaria phylum , the Nematoda also does not have a complete coelom

Like the Schiphozoa and Nematoda Phyla , pollinators or insects are also invertebrates and they belong to the category of Arthopods...
