Sponges by Sean

This week we in biology we learned about phyla by working on our project. We learned about multiple phyla like porifera which are a aquatic invertebrate animals that comprises the sponges. We also learned that they have no circulatory system and that they are filter feeders that eat tiny floating particles and plankton that they filter from the water that flows by them. The food is collected by specialized cells called choanocytes and brought to other cells by amoebocytes. What i find interesting is that there are so many types of phyla.



Interesting Facts:
            -They don't have spines
            -There are different classes of phyla
Question:

            -Is there phyla around you everyday?
