Phylum porifera
Features : No symmetry , hollow body cavity , stationary animal, specialized cells but no tissues,spicules exoskeleton.
examples:Scyon,Hyalonema,Spongilla
Phylum Cnidaria:
features
some stationary polyps and some mobile medusoids , entrance and exist through the same digestive tract,Some have stinging cells.
examples : Hydra ,Physalia,Aurelia.
Phylum Platyhelminthes:
features
Parasites, Simple animals with bilateral symmetry,three tissue no body cavity,tubular mouth at mid body.
example : liver flukes , tape worms.
Phylum nematoda:
features
Tube within a tube arrangement , muscle and nerves developed.
example: round worms, wucheraria brancrofti.
Phylum Annelida:
Features: Setae used for movement, Bilateral phylum with segmentation,complete digestive tract.
examples : Neris , Aphrodite , Megascolex
Phylum Arthropoda :
Features: Has the most species , Exoskeleton present , Hard but flexible bodies with small plates,The first to have jointed legs,The First to fly,Champions of variation in appendages.
example : palemon,Limulus,Lobsters,preying mantis etc.
Phylum Mollusca:
Features:
most have calcium containing shell,Mantle of tissue coverin the body ,Some propel using siphon,Muscular foot used to move,Radula is used to feed.
Examples:Neoplina,chiton, Dentalium, Sepia ,Octopus.
Phylum Echinodermata:
Five part symmetry , Tube feet , Water flows through canals of body,All live in sea,Have spines covered with a thin skin,Stationary animal.
examples
Cucumaria, Ophioderma,Echinus.
Vertebrates:
Internal skeleton,Jaw and skull as part of evolution,all have vertebral coloumn, Humans
