$\sf \blue{ᴘᴏʀɪғᴇʀᴀ :-}$

• Sponges, the members of the phylum Porifera are a basal Metazoa (animal) clade as a sister of the Diploblasts.

• They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.

• The branch of zoology that studies sponges is known as spongiology.

• Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process.

• Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes.

• Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals.
