The document discusses the classification of organisms within the Kingdom Animalia. It describes how Animalia is divided into invertebrates and vertebrates. Several phyla are listed for each group. Specific details are provided about the phyla Porifera and Coelenterata. Porifera includes sponges, which are non-motile marine organisms with pores, chambers, and silicon/calcium skeletons. Coelenterata includes cnidarians like hydra and corals, which are aquatic animals with exoskeletons and internal cavities formed from two cell layers.

8. PHYLUM PORIFERA
 Word meaning : Organisms with pores
 Commonly known as Sponges
 Marine Organisms
 Non-motile animals – attached to a support
 Possess a large cavity inside their body –
spongocoel
 Pores + Spongocoel
 Waste material
 Outer surface is hard ( skeleton )
Water canal system
Osculum
Calcium
and Silicon

11. PHYLUM COELENTERATA ( CNIDARIA )
 Aquatic animals
 Outer surface is hard – Exoskeleton
 There is a cavity in the body
 Body is made up of two layers of cells:
 One makes up cells on the outside of
the body,
One makes the inner lining of the body
 Some lives in colony , some have
solitary life
