The sponge was originally a multicellular animal. As the most primitive and simple multicellular animal. Sponges have lived on Earth for at least 600 million years, making them one of the planet's oldest inhabitants.
Sponge cells are mainly composed of calcium carbonate or silicon carbonate and contain a lot of collagen. Sponges have no central nervous system and digestive organs, nor do they have limbs, heads, and tails. But the bulk loofah 6 inch is full of tiny holes and sieve-like rings. There are many flagella in these densely packed pores.
By using the swing of the flagella, the sponge city can inhale seawater, as well as organic debris such as oxygen, bacteria, microalgae, and microphytoplankton organisms in the seawater, and then we filter through a ring to absorb and learn the nutrients in it to survive as a business base, and expel the rest as useless substances.
In people's daily life, sponge is a kind of commonly used thing. The sponges used by people are actually divided into natural hemp sponge and artificial sponges.
