Flagellated choanocytes
WebSponges are unusual animals that lack definite organs to carry out their various functions. The most important structure is the water-current system, which includes the pores … WebThe flagella of the choanocytes are flexible with slight stiffness at the base. As a result the flagella beat from base to tip creating a water current in the same direction and drive the water from the flagellated chambers to the spongocoel.
