- - - - filter feeders
        
        most are hermaphrodites, functions as both male and female
        
        lack tissues, but group of similar cells act as functional units
        
        Amoebocytes, totipotent cells, found in the mesohyl, play digestion and manufacture of skeletal fibers roles
        
        Choanocytes, flagellated collar cells, generate a water current through and ingest suspended food
  - - - including jellies, corals, and hydras
        
        carnivores that use tentacles to capture prey
        
        Diploblastic; radially symmetrical; gastrovascular cavity (digestive compartment with a single opening)
        
        Two type of body plan
        
        A medusa ; bell-shaped body with its mouth on the underside
        
        A polyp adheres to the substrate by the aboral end of its body
    - - Lophotrochozoa
        
        Phylum Platyhelminthes
        (Flatworms)
        
        live in marine, freshwater, and damp terrestrial habitats
        
        have gastrovascular cavity, a dorsoventrally flatten body shape
        
        they can be parasites such as trematodes and tapeworms
        
        Lophophorates
        
        Coelomates with lophophores
        (crown of ciliated tentacles around their mouth used for feeding)
        
        Phylum Ectoprocta
        
        Phylum Brachiopoda
        
        Phylum Mollusca
        
        includes snails, slugs, oysters, calms, octopuses, and squids
        
        most of them inhabit marine, some inhabit fresh water
        
        they are soft body animals, but most are protected by a calcium carbonate shell
        
        there are four major classes in molluscs

        Phylum Annelida
        
        divided in to three clades
        
        Polychaeta(polychaetes)
        
        most are mobile marine predators or grazers
        
        have a pair of paddle-like or ridge-like structures called parapodia on each body segment
        
        Oligochaeta(oligochaetes, earthworms)
        
        eat through soil for extracting nutrients, they are hermaphrodites but cross-fertilize
        
        Hirudinea(leeches)
        
        most of them live in fresh water, some are marine or terrestrial
        
        parasites that suck blood, chemical called hirudin to prevent blood clot
