9 PHYLA OF KINGDOM ANIMALIA

1. Phylum Porifera
2. Phylum Cnidaria
3. Phylum Platyhelminthes
4. Phylum Nematoda
5. Phylum Annelida
6. Phylum Arthropoda
7. Phylum Mollusca

1. PHYLUM PORIFERA

 

Leucosolenia sp.  

-Porifera in Latin means "pore bearing"
-Parazoa : Animals that lacking true tissues
-The most primitive multicellular animals
-Among the most abundant animals in the deep ocean

-Sponges are aquatic animal, mainly marine, size ranging from 1-200cm in height
-Lack nerves or muscles
-Mostly are asymmetrical

 

• Reproduce sexually & asexually

• Sexual reproduction: Hermaphroditic (it can produce both eggs & sperm)

• Asexual reproduction: Budding and fragmentation

Sessile filter feeders ????

 

• Sponges are water filtering system
• Water contain food particles enter through pores called ostia , then through spongocoel and finally exits through large opening called osculum.

That's why they are called FILTER FEEDERS !!!!!

 

 

 

UNIQUE CHARACTERISTICS

 

 

                                                                              Amoebocytes
    

•  Wandering the mesohyl

• Take up food from the water and from the 
  choanocytes digest the food carry the nutrient
   to other cells.

Porocytes 

• forming the pores/canals/ostium
