What is another word for parazoan?
Pronunciation: [pˈaɹəzˌə͡ʊn] (IPA) 
"Parazoan" is a term that refers to a group of animals that lack true tissues or organs. Synonyms for this word include "poriferan" or "sponge." These creatures are considered one of the simplest forms of multicellular animals and are known for their ability to filter large amounts of water to obtain food. While sponges themselves are not particularly complex, they are of great interest to scientists because of their ancient evolutionary history that dates back more than 600 million years. By studying these primitive organisms, scientists hope to gain insight into the origins of more complex life forms.
