1. Sponges nutrition
Holozoicas sponges are basically feed on organic material particles are suspended in
water. As sessile have to filter the water to catch food. Coanocitos flagella of inward
currents create the sponge. The water flowing inside a low pressure, but the volume of
water contained in a sponge is high. When observed in electron microscopy shows that
the collar is formed by a coanocito fibrillar structure similar to Choanoflagellates protozoa.
